Stepper Motors

Our many years of comprehensive experience in developing and manufacturing hybrid stepper motors have resulted in an extensive range of standard and specialized models, which are also primarily manufactured at the production site in Sömmerda. All of MICROSTEP's drives are characterized by:

a high level of reliability
the use of high-energy magnetic materials
the fundamental use of precision ball bearings
high dynamics due to the use of laminated rotors
excellent suitability for microstepping operations.

The hybrid stepper motors are organized into the following sizes:

Step angle [°]	0,9	1,8	1,8	5
Motor size [mm]	39 x 39	39 x 39	56 x 56	44 x 44

All of the standard types can be adapted for individual customer requests at short notice, where technically possible.

The stepper motors are organized into the following main groups, according to structural design.
