premo^® SP Line

Name: premo® SP Line
Brand: WITTENSTEIN group

Servo actuator

The premo^® SP Line servo actuator impresses with its low weight and short overall length – ideal for moving axes and fast cycle times. The output shaft variants (smooth, feather key or splined shaft) enable a flexible mechanical connection. The motor encoder is equipped with a resolver as standard, other encoder options are available.

16 – 100

Ratio

32 – 315 Nm

Max. torque

≤ 3 – 5 arcmin

Backlash

Higher efficiency

The low moment of inertia and high power density result in improved utilization of the energy supplied

Smaller footprint

The short installation length of the servo actuators helps to make the machine design more compact

Increased productivity

The increased rigidity and dynamics achieve a higher output in your machine
