AC motor

asynchronouspermanent magnet

The motors included in this series are normally used for spindles, lathes, grinders, milling cutters, conveyors, roller ways, pumps and centrifugal fans, in the textile industry, etc. With optimised operating functions, this series of motors for inverter duty has been developed focusing on the design of the magnetic circuit built with low-loss magnetic laminations and on the configuration of the magnetic circuit. The windings are designed with special features that eliminate the inverterinduced harmonics that generate disturbance for the machine. Fed with voltage that varies in relation to the frequency, the motor runs at constant torque up to the rated frequency. Instead, for higher frequencies it operates at constant power. The windings are built with a leading brand wire with double enamel, class H insulation made with high-temperature resistant polyesterimide resins. Insulation between the phases and to earth is optimised by the excellent insulating materials used, such as Mylar and pure Nomex.
