Custom drive systems from Sömmerda
MICROSTEP GmbH Schrittmotoren, Steuerungen, Bewegungssysteme, based in Sömmerda, Thuringia, develops and manufactures custom stepper motors, linear actuators, controls and complete mechatronic motion systems for industrial applications. The portfolio includes hybrid, hollow-shaft, permanent-magnet and geared stepper motors, lead screws, encoders, brakes and integrated controllers (SmartStep) with PSC2 software. Manufacturing covers automated stacking of stator and rotor laminations made of electrical steel, winding technology using copper (flyer, needle and flat wire windings), contacting and connection technologies, as well as the assembly of complete systems combining motor, mechanics, electronics and software. Application areas include valve controls, dosing systems, positioning drives and compact automation solutions, especially where standard motors reach their limits – for example at high temperatures, in humid conditions, under vibration or in restricted installation space. Customers come from industries such as mechanical engineering, medical technology, HVAC, valve technology, special machinery, laboratory automation and environmental technology. According to the company profile, products are delivered worldwide.

Materials and processes
Electrical steel (stator/rotor laminations)
Laminated rotors and stator laminations with single-side varnish insulation form the magnetic heart of the hybrid stepper motors.
Copper (wire and flat wire)
Used for flyer, needle and flat wire windings of the stator windings.
High-energy magnetic materials
Used in rotors and high-temperature variants for high efficiency and temperature resistance.
Brass (nuts)
Nuts for in-house lead screws with good emergency-run characteristics.
Bronze (nuts)
Nuts for lead screws, designed for service life and friction behavior.
Plastic (nuts)
Special plastic nuts for low-maintenance linear actuators without additional hardening.
Stainless steel (sleeve)
Sleeve for stepper motors, especially for medical technology applications.
