Description

The principle factor of volume size of motor is torque rather than power. The torque density of general permanent magnet synchronous motor is 20~50kNm/m3, and when in high torque density, need take special cooling measure. If use general permanent magnet synchronous motor replacing induction machine, belt pulley, gear box, and drive beam pumping unit, the volume of motor will exceed mechanism reduction gear box with same torque specification. The permanent magnet integrated motor can use general no code transducer to control.
