DC-Micromotors

Precious Metal Commutation

Micro motor features

The main difference between FAULHABER DC micro motors and conventional DC motors is in the rotor. The rotor does not have an iron core but consists of a self-supporting skew-wound copper winding. This featherweight rotor has an extremely low moment of inertia, and it rotates without cogging. The result is the outstanding dynamics of FAULHABER motors. For low power micro motors, commutation systems using precious metals are the optimum solution because of their low contact resistance.

FAULHABER precious metal commutated motors range in size from just 6 mm to 22 mm in diameter.

FAULHABER completes the drive system by providing a variety of additional hightech standard components including high resolution encoders, precision gearheads, and drive electronics. FAULHABER specializes in the modification of their drive systems to fi t the customer’s particular application requirements. Common modifications include vaccuum compatibility, extreme temperature compatibility, modified shaft geometry, additional voltage types, custom micro motor leads and connectors, and much more.

Micro motor benefits

  • Ideal for battery operated devices
  • No cogging
  • Extremely low current consumption – low starting voltage
  • Highly dynamic performance due to a low inertia, low inductance winding
  • Light and compact
  • Precise speed control
  • Simple to control due to the linear performance characteristics
