We design BLDC and PMSM motors from the torque–speed curve up — then prototype them, prove them on the dyno, and take them to production. Need the gearbox and a sealed housing around it too? That's one drive unit, one team.
Not a factory. Your engineering partner, on your side of the table.
Every supplier vetted, every quote pushed, every result measured against your spec — because the work answers to you, not to a production line that needs filling.Motor, gearbox and sealed housing — designed together as one unit, or any single part on its own. From a sketch on a napkin or a spec you already have, the path is the same: hardware that meets the number, made repeatably, at a price that holds.
Electromagnetic and mechanical design of brushless motors built around your real constraints — torque, speed, envelope, voltage, thermal and cost. Start from a requirement, or hand us a design to refine and make manufacturable.
Gearheads designed and matched to the motor, not bolted on after. Planetary, spur or right-angle reductions sized for the torque, ratio, backlash and life your application needs — delivered as one integrated drive.
Housings engineered to the job — any size, the right material, sealed to your environment. Compact brackets through fully enclosed assemblies; machined or cast in aluminium, steel or polymer, with ingress protection up to IP68.
Finite-element analysis before metal is cut — electromagnetic, thermal and structural. We see flux density, torque ripple, losses and hot-spots on screen and design them out early, where changes are still cheap.
Short-run prototypes assembled and instrumented in our own space, then characterised — not just built. Bench and dyno data put against the spec so you know what you actually have before any money goes into tooling.
Sourcing matched to your part, not our convenience — suppliers vetted, samples qualified, pricing negotiated hard. We manage the certification path so the part that ships is the part that passed. Cost-driven manufacturing across Asia, with US and EU options when speed, IP or compliance call for it.
Finite-element analysis turns guesswork into evidence. We model the magnetics, the heat and the stresses, read the problems off the screen, and design them out while a change still costs an afternoon — not a tooling run.
Scroll to pull a brushless motor apart — shaft, end bells, rotor and magnets, stator windings, finned case. These are the parts we design, simulate, prototype and source, one at a time.
Five stages, one person accountable across all of them. You always know which stage you are in and what proves you are ready for the next.
We pin the numbers that matter — load, duty, envelope, supply, cost — and agree what "done" measures as.
Magnetics, windings, rotor and housing designed to hit the target with margin, not luck.
Short run assembled and instrumented. You get real hardware in hand, fast.
Dyno and bench data against the spec. We iterate on evidence, not opinion.
Vetted supplier, qualified samples, certification, negotiated price — into series.
An American engineer trained at the University of South Florida in Tampa, with over 15 years focused exclusively on brushless motors. George Motor Design pairs that hands-on BLDC expertise with an in-house assembly space and vetted supply-chain partners across Asia — design, simulation and sourcing under one roof.
We keep the roster deliberately small, so every program gets an engineer's full attention rather than a queue position. Close enough to the factories to walk the floor; native to the way Western teams work.
Fifteen-plus years specialising in brushless motors — and nothing but brushless motors. Drones or appliances, power tools or robots, a coin-sized fan or a traction drive: if it runs on BLDC, it's what we do all day.
The power range we design across — micro fans to traction drives
You pay for the engineering you actually need — billed transparently and quoted up front, per project. No bloated retainers, no surprise invoices, no paying agency rates for a junior's time.
Certain design and drafting work starts as low as $40 an hour. You get senior BLDC know-how on the hard parts and efficient rates on everything else.
Before any work starts you get a clear, fixed-scope number for the stage ahead — feasibility, design, prototype or sourcing. You decide with the price in hand.
Prototypes are priced at cost plus a fair build fee, and production is negotiated hard on your behalf. We make money on the engineering, not by marking up your motors.
*Hourly rate varies by role, scope and complexity; senior simulation, magnetics and certification work is quoted accordingly. Every project gets a clear number before a single hour is billed.
Plain-spoken writing on motor design, validation and getting a brushless part into production without the usual surprises.
No-load spin tells you almost nothing. Here's what loaded testing reveals — and why it's the cheapest insurance you'll buy.
Read →EMC, low-voltage, machinery — which directives bite, when they apply, and how to avoid finding out the hard way.
Read →What really happens between "I need a motor" and a qualified production part — stage by stage, with the parts that slip.
Read →A message with the rough torque, speed and size you need is plenty to start — WhatsApp is fastest. You'll talk to an engineer, not a sales desk.
Send the basics — what the motor drives, rough torque, speed and voltage, size limits, and target volumes. Gaps are fine; we'll fill them in together.
