Frameless Torque Motor

Description:
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.

Direct Drive Technology:
1.High torque with low speed for maximum precision
2.Increased motor stiffness for dynamic operation
3.Short motor lengths
4.Less vibration for quiet operation
5.Increased efficiency
6.No need for mechanical transmission elements (gearboxes etc)
