Kind Code:
A1
Abstract:
An unloading alternate current permanent-magnet synchronous dragging machine
comprises a dragging machine seat(18) and alternate current permanent-magnet
synchronous motor(14) with an encoding device(15), a dragging wheel(1), a drum-typed
or plate-typed clasping brake system(9) and a turning gear. The alternate current
permanent-magnet synchronous motor(14), the ragging wheel(1), the drum-typed
or plate-typed clasping brake system(9) and the turning gear are all arranged
