Pole-changing motors SENSE EXPERIENCE EXPERIENCE VISION

Pole-changing motors Drives for industry, craft trades and agriculture Pole-changing motors Versatile, reliable and efficient Pole-changing motors are designed for drives with constant torque characteristics and drives with quadratically rising torque because of the torque characteristics of the working machine. The motors can be calculated only for one rated voltage, for example 230 V, 400 V or 660 V. They are generally designed for direct starting by using the different poles. 60-Hz-design or special volt­ ages according to IEC-38 are available as option. The pole-changing is done by › two...
