/> Frameless high torque motors by Rozum Robotics

Frameless AC Motor Kits 

FMI by Rozum Robotics is a series of compact enhanced performance brushless motors. FMI is a rotor plus stator kit—a three-phase brushless motor can be encapsulated into any housing of your choice. The direct drive brushless motor has no bearing, or shaft, or endbells. The motor is directly integrated into the rotating shaft of the machine. The hollow-shaft design allows for easy integration. 



Models available

FMI brushless motors are basically compact high torque frameless motor kits. Whether you choose a smaller modification or larger one, torque density is higher compared to that of other AC brushless motor manufacturers. Detailed technical characteristics are given below.

Where to Apply:

When designing FMI AC frameless motor kits, we kept in mind projects where compact size and high power density matter most. As a result we developed direct drive brushless motors - small in size but with high power-to weight-ratio. Still, FMI is a safe kit: it is a low voltage 48V brushless motor. Typical industries where FMI is used:

  • medicine
  • robotics projects
  • industrial equipment
  • moving elements
  • pumps, compressors, etc.
