AC Synchronous Servo Motors

Intact supplies brushless, rotary current, synchronous servo motors with three phase windings for demanding servo applications. These motors have permanent magnets in the rotor. The neodymium magnet material and the low inertial moment contribute significantly in making these motors highly dynamic and allow them to have a very high specific power, low cogging, bearing high overload without any risk of demagnetization. The robust, compact motors with high power density are available in various sizes and fine graduations, whereby customization is possible. Motors are available in a wide range of torques.
