DC-Micromotors

Originally invented by Dr. Fritz Faulhaber Sr. and patented in 1958, the FAULHABER coreless (or ironless) progressive, self-supporting, skew-wound rotor winding is at the heart of every FAULHABER DC-Micromotor.

This revolutionary technology created new possibilities for customer application of DC-Motors where the highest power, best dynamic performance, in the smallest possible size and weight are required.

Features and benefits

No cogging torque · Smooth position and speed control · High efficiency· Low Noise · High torque · Low Weight · Very low rotor inertia · Dynamic start-stop operation · Low torque ripple and EMI
