Brushed DC motors
DC-Micromotors with precious metal commutation
Originally invented by Dr. Fritz Faulhaber Sr. and patented in 1958, the System FAULHABER coreless (or ironless) progressive, self-supporting, skew wound rotor winding is at the heart of every System FAULHABER DC Motor. This revolutionary technology changed the industry and 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.
The main benefits of this technology include no cogging torque resulting in smooth positioning and speed control, higher overall efficiency than other DC Motor types, extremely high torque and power in relation to motor size and weight, and a linear relationship between load to speed, current to torque, and voltage to speed. The very low rotor inertia results in superior dynamic characteristics for starting and stopping and the motors exhibit extremely low torque ripple and EMI.
