COTS Rotors & Stators.
Rotor and stator sets designed to meet the high power-density requirements of today's industrial and mobility devices. Available as standard, modified (mCOTS), and fully customized products.
Built for power density.
Configurations that drop into your existing design.
Our line of COTS stator and rotor sets covers diameters from half an inch to 36 inches and power levels from 0.5 W to 150 kW. Every set is offered in configurations that facilitate integration into existing designs — frameless as standard, with housed configurations available.
When a catalogue part is close but not exact, the same sets are available as modified COTS (mCOTS) or fully customized products to meet a wide variety of application requirements.

Why designers spec them.
Lightweight, high power density
Maximum output from minimum mass and volume — the defining requirement of modern industrial and mobility devices.
Extreme shock and vibration tolerant
Built to keep running in environments that destroy lighter-duty parts.
High stiffness, low rotor inertia
High mechanical stiffness with low rotor inertia for efficient control and smooth, accurate motion.
Easy integration
Frameless sets sized to drop into existing designs without re-engineering the surrounding assembly.
Standard sets, on the shelf.
The following standard rotor and stator sets are in stock. Many other options are available on demand.
