According to Micromo, its compact Series 2057 BHS brushless linear motors are fast and resistant to vibrations and overheating. The motors will be used to power small hand-pieces for sensitive applications such as dentistry and surgery. Speeds up to 40,000 rpm can be controlled by the user, and the motors will withstand intermittent overload for short-term dynamic applications. Preloaded ball bearings allow for maximum 22 N radial loading and 75 N axial loading. Replacement of the front bearing extends the service life of the motor. Standard motors employ digital Hall sensors for commutation; optionally, analog hall sensors can be used for slow speed operation. To complete the drive system, gearheads, magnetic and optical encoders, and drive electronics are available.
