Frameless Direct Drive Torque Motors

Compact, Fully-integrated motor with improved dynamic performance.

Widely used for applications like Gimbals, Robot arms, Index tables and many such high precision applications, Torque motors from Pranshu comes with Large through holes and low profile motors.

Frameless torque motors consist of a separate rotor and stator which are assembled directly inside the machine. 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.

Compact, precise, and smooth motion are key features of these motors.
