Special Solutions

Starting with our extensive standard range of motors and actuators, we worked with our customers to develop and complete a large number of customized, tailor-made drive solutions.

In particular, you benefit from our competence and experience when it comes to using our drives in extreme environmental conditions. A particular focus here is on refrigeration and air conditioning technology.

The maximum operating ambient temperature for standard motors is 55° C. Special structural measures allow us to design every 0.9° and 1.8° stepper motor with a #39 flange dimension as a high-temperature motor. These motors are certified for a constant ambient temperature of over 100° C, depending on their overall length.
The drives described here are just a few examples of our specialized solutions; the idea is to awaken your interest so we can work with you to make new ideas a reality, and help secure your competitive advantage with innovative new products. Give us a challenge.

Hohe Temperaturen

The standard stepper motors of the MICROSTEP series are generally approved for an ambient temperature during operation in the range of +5° to +55°C. Use in the freezing range is safely possible down to -20°C if the customer has ensured by design that no condensation can enter the motor. In most cases, use at higher temperatures is more critical. For this reason, we have developed stepper motors that can be used up to an ambient temperature of 90°C by means of a special design and by optimizing the materials used. With a suitable electrical design of the motor and adaptation to the control system, even ambient temperatures of over 100°C are possible.


In many areas of industry, drives must also be used in ambient conditions characterized by moisture, wetness, dust exposure or even aggressive media. Here, standard stepper motors with a degree of protection of IP 30 or IP 40 are no longer suitable. For this reason, MICROSTEP GmbH has developed stepper motors that are additionally provided with a special housing and thus offer effective protection against external environmental stresses.


The double stepper motor generates two independent rotary motions in one axis, with the usable shaft ends arranged directly behind each other.


  • Mounting a dual motor in the application is easier than mounting two separate motors.
  • The adjustment required to align the rotor shafts with each other is no longer necessary.
  • Independently controllable rotary movements on one axis with regard to direction of rotation, speed and torque.

Wherever little space is available or a high torque-to-volume ratio is required, the use of a double stepper motor can often make more sense than two separate stepper motors. The operating conditions correspond to those of normal stepper motors.


The stroke/rotation actuator is designed for applications in which both a rotary and a stroke movement are to be implemented in the smallest possible space. Both movements can be executed independently of each other, as both axes are driven by two separate stepper motors.
