What are the components of a direct-drive frameless motor kit?

A direct-drive frameless motor kit includes a stator and rotor, without a housing or other mechanicals such as bearings and strain-wave gears. The stator consists of an iron stack, which provides rigidity and an end to the magnetic circuit, a copper winding (3-phase AC in case of our Omni+ Series of motors), and can also include optional features such as Hall-effect and temperature sensors. The rotor includes an even number of permanent magnets, alternating polarity, and typically includes a backiron – completing the magnetic circuit.
