Frameless torque motor
Leroy-Somer’s frameless torque motors consist of a separate rotor and stator which are assembled directly inside the machine. The result is a compact, fully-integrated motor with improved dynamic performance.
The rotor and stator can be modified to match your machine and the motor winding can be customized to adapt the motor speed to the application. Various encoder solutions, solid and hollow shafts are available to ensure the rotor speed and motor position.
