coupling, which has the disadvantages of low efficiency, large size, maintenance of high
workload and noisy running; or direct drive type, that is, the permanent magnet
synchronous motor directly drives the drum, which has the disadvantages of large size,
high cost and large capacity required by the frequency converter.

realized, and the thermal influence between them is reduced; the brake is directly
connected with the output shaft at the other end of the permanent magnet synchronous
motor, so that the braking efficiency of the drive device is improved, and the volume of the brake is relatively small because of direct braking of the permanent magnet synchronous motor, thereby further reducing the volume of the whole device.
