Bison's new motor line consists of variable speed AC motors that run synchronously with an input AC frequency in applications that require synchronized movement across multiple axes. The motor rotors contain magnets that precisely follow the internal rotating magnetic field without the slip commonly seen in general induction motors. As a result, the VFsync PMAC motors are highly effective for applications that require velocity control, with a lower price point than servo counterparts.
The VFsync PMAC motor line fills a gap in the fractional horsepower and integral horsepower market between a simple induction motor and a more complex servo motor. Machine builders looking for energy-efficient motor solutions that draw less power but don’t necessarily require the level of feedback and sophistication found in a servo motor see significant cost and functionality benefits from the VFsync PMAC motors.
