Overview
PU300G Key Specifications
The PU300G is the smallest module in Gleagle's push-up lineup — and our best-selling one. Same self-developed control architecture as the 3kg flagship, scaled into a footprint that disappears inside a display base.

* Extended float (25mm) requires payload reduction to ~50% of rated max. Measured at 25°C, no-load, tolerance ±2mm.
Most levitating gifts and retail displays weigh far less than people expect — a watch, a ring box, a perfume bottle, a coin, a sample jar. The PU300G was built for exactly that range. It floats up to 300g on an 18mm cushion of air, centers whatever you place on it automatically, and runs 24/7 on a simple DC 12V supply. That is why it ships more units than any other module we make.
300g max payload — the sweet spot for jewelry, watches, coins, cosmetics, collectibles and product samples
Smallest module in the PU series — hides easily inside custom bases, packaging and point-of-sale displays
Passive + active hybrid design — the magnet ring carries the load passively on Z with zero holding power; the correction electronics handle only X/Y centering
Slow-servo MID bias system — clamps the coil operating point mid-scale while floating, then drifts it back to zero current when idle — fully in-house slow-servo design
Over-temperature auto-shutoff — on-chip sensor protects the circuitry during continuous operation
Full OEM/ODM — housing, magnet size, float gap, firmware and branding, all customizable
This electromagnetic suspension system requires a little practice to operate — first-time users should practice finding the magnetic balance point. Once mastered, the PU300G delivers reliable, energy-efficient 24/7 levitation for retail, gifting and exhibition environments.
Please read the operating instructions carefully before first use. Proper handling ensures a successful first levitation and prevents equipment damage.
Mechanical
Dimensions & Mounting
A Ø100 mm body with four mounting ears — the module drops into any custom base with four screws. All dimensions in millimeters.
Four Ø3.05 mm through-holes on 107 mm centers (4 ears equally spaced at 90°). Overall footprint Ø114 mm × 18.8 mm — 19.30 mm with the wireless transmitting coil option. STEP files and DXF drawings available on request.
Options
Magnet Stack Options
The base magnet is a multi-layer stack, not a single disc. Four standard configurations trade float height against stability and load capacity — heavier objects want a larger diameter, lighter objects can float higher.

Highest float, reduced stability — best for small, light objects
Rule of thumb: the heavier the object, the larger the magnet diameter you need. D50×12 is recommended for payloads approaching 300g; D30×12 is for featherweight display pieces where float height matters most. Custom stacks on request.
How to Choose the Right Magnet Stack
1. Tall objects (over 10 mm), irregular shapes (center of gravity off the geometric center), or payloads over 150 g — go with the D50 series for maximum stability. If magnet size is not a constraint, choose D50 directly — it is the most stable option.
2. Very light objects (under 50 g) with regular shapes — spheres, cylinders, square boxes — the D30 works: the smallest magnet, easiest to hide inside your product. The trade-off is lower stability — please test thoroughly and evaluate the risk before ordering.
3. D40 and D35 are the middle grounds — choose mainly by the space available inside your product. Rule of thumb: within the space you have, go as large as you can — a larger diameter means better stability, a wider controlled field area, and a broader sensing range.
Wireless Power Option
If You Need Wireless Power Transmission
Add a spiral planar coil pair: a transmitting (TX) coil in the base and a receiving (RX) coil on the floater. It powers LEDs or other small loads on the floating object — no battery, no wires across the gap. Two placement rules decide how much power you actually get.
TX · BASE SIDE
Transmitting Coil
Mount the transmitting coil directly on the system's magnet ring — flush against it. No standoff, no offset: the coil face sits on the ring.
RX · FLOATER SIDE
Receiving Coil
Mount the receiving coil at the bottom face of the floating magnet — or at minimum, level with the magnet's bottom face. Never recessed above it.
The closer the two coils, the higher the received power — and the brighter your wireless LEDs. Coil distance follows your float gap — see Magnet Stack Options above.
Wireless power transfer is a complex system that demands extensive testing and tuning. Every product shape — and every coil mounting position — shifts the resonant frequency. Only at the optimal resonance point does the system run at its lowest power draw while delivering maximum received power — and the brightest LEDs. This is precision engineering: if you want the absolute best result, send us your product and our engineers will tune the resonance for you.
Rule of thumb: for display applications where visual height matters, stay within 50% of rated max load. Full specs & pricing: Levitation Modules · Not sure which size? Read the Module Guide
Technology
Flagship Control, Compact Footprint
Like poles repel — the PU300G turns that one line of physics into a hybrid levitation architecture. A magnet ring carries the load passively on the vertical axis: pure permanent-magnet repulsion, zero circuits, zero power. Active electronics are reserved for the one thing passive physics cannot do — centering. Fully differential sensing channels watch the floater on X and Y, and an in-house slow-servo MID control loop nudges it back before any drift becomes visible.
1. Passive Z Stability
The magnet ring holds the load with zero holding power — physics, not electronics.
2. Differential Sensing
Fully differential X/Y channels cancel thermal drift by construction.
3. Slow-Servo MID Centering
Real-time correction by Gleagle's in-house MID control — centered means zero coil current.
4. Slow-Servo MID Bias
Clamps the operating point under load, drifts back to zero current at idle — standby in the fraction-of-a-watt class.
Ultra-Low Power by Architecture, Not by Throttling
A compact base has far less thermal headroom than a large one — heat has nowhere to go. Generic small modules fight this by throttling power, which costs you float height and stability. The PU300G barely makes heat in the first place: the load rides passively on the magnet ring, so the coils draw current only while correcting — and sit at zero current once centered. Static draw is around 0.25W, roughly a fifth of pull-up designs. Less power in means less heat out: the small module runs cool through 24/7 retail operation, without giving up its 18mm float gap.
Everything is developed in-house: PCB design, control circuitry, magnetics and coil winding, by Gleagle's 15+ R&D engineers. No outsourced core technology.
1. Levitation height tolerance: ±2mm. 2. Maximum height is measured under no-load conditions at 25°C. 3. Height decreases proportionally as payload increases — expect roughly the rated gap at light loads and about half near rated maximum.

Guide
Operating Instructions
From the official Gleagle user manual. A few attempts and you will find the balance point with ease.
1
Set Up the Base
Place the base on a flat surface free from ferromagnetic materials. Connect the DC 12V adapter and turn on the power.
2
Find the Balance Point
Hold the magnet disc over the base at about 15cm (6 inches), aligned with the center. Slowly move it downward — the balance point sits approximately 18mm above the base surface.
3
Release Gently
When the magnet feels almost weightless — neither falling nor pushed away — release it gently. If it falls, start over from Step 2.
4
Place Your Object
Once the disc floats stably, gently place your object on it, centered vertically. If the disc drops, protect the base with foam padding and try again.
— From the User Manual: TIPS It might require some practice to operate correctly initially. Do not be discouraged; try again. You will soon find the balance point with ease.
The magnet disc may detach and strike the base forcefully — consider placing a soft plate on the base while practicing. Auto-shutoff: the built-in temperature sensor cuts power if the base exceeds the safety threshold. If levitation fails after several attempts, wait at least one minute before retrying.

Frequently Asked Questions
What is the maximum weight the PU300G can levitate?
300g maximum. For the best visual height and long-term stability we recommend staying within 150g — roughly the 50% load rule. At light loads you get the full 18mm float gap; at reduced payload the extended configuration reaches 25mm.
What kinds of products is the PU300G best for?
Anything regular-shaped, non-ferromagnetic and up to 300g — jewelry and ring boxes, watches, coins and collectibles, perfume and cosmetics jars, small figures, lightweight decor, and product samples. It is the module behind most compact levitating gift and counter-display projects we ship.
How is the PU300G different from the bigger PU modules?
Same control architecture — in-house slow-servo MID control with near-zero power draw — in the smallest footprint of the series. You trade payload and float height for easier integration, lower cost per unit, and a base that disappears inside your product housing. For heavier objects, see the full lineup up to the 3kg PU3000G.
Module or finished product — which do I need?
The PU300G is the bare levitation module: you integrate it into your own base, packaging or product. If you want a ready-to-use display out of the box, look at our finished products — for example the Programmable LED Levitating Display Stand, which adds world-exclusive wireless LED lighting to the same push-up platform.
Can I order a single sample?
Yes. MOQ is 1 unit for the standard PU300G. Evaluation samples can ship as fast as 24 hours via DHL/FedEx/UPS. We encourage testing a sample with your actual product before placing bulk orders.
Do you offer OEM/ODM customization?
Yes — magnet disc size, float gap, load tuning, coil winding, housing, PCB layout, firmware and branding. Custom projects typically require 7–15 business days, depending on complexity and the agreed production scope.
What certifications does the PU300G have?
Gleagle is ISO 9001:2015 certified. Available compliance documents depend on the exact module, configuration and destination market; please confirm the applicable documents before ordering, and each unit undergoes burn-in testing before shipment with individual calibration. Third-party factory inspection is accepted.
Is PU300G the right choice for a 200–300g standing figure?
Usually no. A standing figure is often top-heavy, so weight alone does not determine stability. For a 200–300g figure, we normally recommend the PU500G for extra headroom. Lower the center of gravity, add weight near the feet, or consider a seated pose.
Can the PU300G be used in a school exhibition?
Yes, for supervised display inside a closed cabinet or protective enclosure. It is not a toy and is not intended for children to operate. Adults should handle installation. The main foreseeable risk is mechanical: if a student touches or disturbs the floater, it may detach and fall.
Which magnet, power adapter and wireless receiving coil does the PU300G use?
D50×12 is the largest standard magnet option and the preferred choice for maximum stability near the upper payload range. A country-specific power adapter is included. Check your country → With the wireless power option, the planar receiving coil sits at the bottom of the floating magnet and can be nearly flush with its lower face; the final stack depends on your configuration.

From Our Inbox: Customer Questions
Q"I want to float a superhero action figure — which magnet stack should I choose?"— Mr. M., United States
AFor a small figure — under 100 g and below 100 mm tall — the D40 stack is a good starting point. If the figure is over 150 mm tall or over 150 g, go straight to the D50: the larger magnet keeps tall, top-heavy objects noticeably more stable. If you are not sure, send us the figure’s weight and dimensions and we will confirm the stack before you order. — Mr. Luo, Chief Engineer, Levitation Systems
Q"Can the rotation be controlled precisely?"— Mr. K., Japan
ANot by the base — and that is by design. The magnetic field is rotationally symmetric, like a frictionless perfect bearing: it neither drives nor brakes the spin. But the object you place decides 90% of it — center the weight and use regular shapes for a near-still display, or keep a touch of deliberate asymmetry for a slow, elegant rotation.
