Unimotor HD and FM
Unimotor servo motors deliver maximum performance for both continuous duty and pulse duty servo applications.
With a stall torque range from 0.72 to 136 Nm and a wide choice of options and accessories, the Unimotor range can be configured to meet your specific requirements.
For specialized applications, we also provide custom-built servo solutions.
To optimize performance, we segment our servo motors by the duty required for the application:
Pulse Duty
Unimotor hd – High dynamic applications requiring hard accelerations and decelerations. Examples are pick-and-place, flying shear and other cut-to-length machines. These applications are characterized by high peak (e.g. 400% overload) and moderate RMS torque.
Continuous Duty
Unimotor fm – High-precision over an extended duration requiring lower acceleration and deceleration rates. Examples include printing, winding and machining. These applications are characterized by moderate peak and high RMS torque.
