ROTEK motor Germany ROTEK model ROTEK price

ROTEK motors are permanent magnet motors commutated or controlled by electronic circuits or current. Permanent magnet brushless motors come in two types: sine wave drive and square wave drive. Those with rectangular wave drive current are commonly referred to as permanent magnet brushless DC motors, while those with sine wave drive current are commonly referred to as permanent magnet AC servo motors. Based on sensor type, they can be classified into sensor-equipped motors and sensorless motors. The ROTEK motor operating principle involves two windings: a starting winding and a running winding. These two windings are spatially displaced by 90 degrees. A capacitor with larger capacitance is connected in series with the starting winding.
