Product Overview
Mid-Size Module. Full-Size Physics.
Most levitating gifts and retail displays weigh far less than people expect — a collectible figure, a perfume bottle, a small sculpture, a product sample. The PU500G was built for exactly that range. It floats up to 500g on a 29mm cushion of air, centers whatever you place on it automatically, and runs 24/7 on a simple DC 12V supply. It covers the payload range we see most often in custom display projects.
500g rated payload · 800g peak — the sweet spot for collectibles, figurines, cosmetics, small electronics and retail displays
Mid-size module in the PU series — hides 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 PU500G 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.

Smallest magnet, highest float — for light pieces where height matters most
Rule of thumb: the heavier the object, the larger the magnet diameter you need. D80×12 (standard) is recommended for payloads approaching 500g; D50×12 is for lighter display pieces where float height matters most. Custom magnet configurations on request.
How to Choose the Right Magnet
1. Tall objects (over 10 mm), irregular shapes (center of gravity off the geometric center), or payloads over 250 g — go with the D80 for maximum stability. If magnet size is not a constraint, choose D80 directly — it is the most stable option.
2. Very light objects (under 50 g) with regular shapes — spheres, cylinders, square boxes — the D50 works: the smallest magnet in this series, easiest to hide inside your product. The trade-off is lower stability — please test thoroughly and evaluate the risk before ordering.
3. D70 and D60 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 Configuration 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 PU500G 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 PU500G 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 stays in the fraction-of-a-watt class, roughly a fifth of pull-up designs. Less power in means less heat out: the small module runs cool through 24/7 retail operation, with float height determined by payload and magnet configuration.
Everything is developed in-house: PCB design, control circuitry, magnetics and coil winding, by Gleagle's 15+ R&D engineers. No outsourced core technology.
Collectibles, figurines, cosmetics, small decor, retail displays
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 — under no-load conditions, the balance point can reach approximately 33mm above the base surface, depending on configuration.
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 PU500G can levitate?
800g peak, 500g rated. For the best visual height and long-term stability we recommend staying within 250g — roughly the 50% load rule. At light loads you get the full 29mm float gap; at reduced payload the extended configuration reaches 35mm.
What kinds of products is the PU500G best for?
Anything regular-shaped, non-ferromagnetic and up to 500g — collectible figures, cosmetics jars, small sculptures, trophies, decor objects, and product samples. It is the module behind most compact levitating gift and counter-display projects we ship.
How is the PU500G 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 PU500G 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 PU500G. 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 PU500G 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.
Which magnet should I use for a large or irregular object around 360g?
Start with the D80×12 for better stability and lateral resistance, especially for a large or top-heavy object. Keep the center of gravity low and aligned with the system's vertical axis. The final float gap depends on the complete object and magnet setup, so confirm it with an actual prototype test rather than a generic estimate.
Can you specify the side-push resistance of the PU500G?
There is no reliable universal newton value. Side-push resistance depends on payload, magnet size, object geometry, center of gravity and float gap. We test it with the actual assembly; quoting a number without that test would be a guess.
Can I use a ring magnet with a center hole?
Not as a standard drop-in option. A center hole changes the magnetic field and may weaken the field where the sensor needs to detect it. Feasibility depends on hole diameter, magnet size and the final assembly. A prototype test is required; do not assume that a smaller hole automatically guarantees compatibility.
Safety
Safety Warnings & Prohibitions
⚠ Warning

From Our Inbox: Customer Questions
Q"I want to float a superhero action figure — which magnet should I choose?"— Mr. M., United States
AFor a small figure — under 100 g and below 100 mm tall — the D70 configuration is a good starting point. If the figure is over 150 mm tall or over 150 g, go straight to the D80: 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 configuration 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.
