Synchronous Servo Motors

With the EZ and EZHD synchronous servo motors, STOBER is offering brushless, permanent magnet and electronically commutated motors with different power profiles. The stator and rotor components have an optimized design in relation to energy for extremely low torque ripple and a high power density in various forms.

The World’s Toughest Gearboxes

STOBER’s motors are dynamic and powerful. Direct mounting reduces inertia by up to 75%, plus you experience higher torque density and stiffness.

These motors are plug ‘n play with a variety of manufacturers, including B&R, Beckhoff, Bosch, Kollmorgen, Rockwell, and Siemens.

KSS: For the toughest environments

The EZ series utilizes a shaft for connecting.

It is extremely compact and dynamic, providing measurably better performance.

K/KL: For right angle applications

The EZHD series is a revolutionary hollow bore motor. It’s ideal for passing media through the center of the motor.

It is extremely compact and has a flange output for easy mounting.
