MICROMO’s New FAULHABER 2057…BHS Brushless DC Servo Motor Robust, High Speed Motors for Medical and Dental Handpieces

The new FAULHABER 2057…BHS Brushless DC Servo Motors are designed to address the specific requirements of the medical and dental hand piece markets.

The new FAULHABER 2057…BHS Brushless DC Servo Motors are designed to address the specific requirements of the medical and dental hand piece markets. While remaining cool to the touch, the high efficiency, slotless design features smooth speed control with a wide continuous duty speed range up to 40,000 rpm. The motors are capable of handling intermittent overload conditions to address highly dynamic motion over shorter cycle times. Low vibration, which reduces user fatigue, and low audible noise are ideal for long periods of use in sensitive medical and dental patient environments.


The new motors come standard with digital hall sensors, and analog hall sensor feedback is available
on request. This option is ideal to eliminate the need for an additional encoder for slower speed
operation for dental implant or endoscopic positioning applications, which can also significantly reduce
cabling complexity within the handpiece itself. Preloaded ball bearings insure that the motors are able
to withstand the radial (22N) and axial loads (75N) in a hand piece. The extremely long service life can
be extended further through the simple replacement of the front bearing.

A wide variety of high precision gearheads, high resolution magnetic and optical encoders and drive electronics are available to complete the drive system. Contact a MICROMO Engineer today to learn more.
