The compact, fully-integrated torque motors from Pranshu deliver enhanced dynamic performance and precise motion control for demanding applications. Commonly used in gimbals, robotic arms, index tables, and other high-precision systems, these motors feature large through-holes and a low-profile design that enable flexible integration and optimal performance.
Frameless torque motors consist of a separate rotor and stator, which are assembled directly into the machine for maximum mechanical efficiency. Both components can be customized — the motor winding, in particular, can be tailored to match the required speed and torque characteristics of your application.
Key Features:
- Compact and low-profile design for space-limited systems
- High dynamic performance with precise, smooth motion
- Frameless configuration for direct integration into the machine
- Customizable rotor, stator, and winding for application-specific optimization
- Ideal for: gimbals, robot arms, index tables, and precision automation
