<p>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 on the dragging machine seat(18). The alternate current permanent-magnet synchronous motor(14) is fixed on the dragging machine seat(18) through a motor end cover(17), the spigot end of the dragging wheel(1) is provided with an end cover(4) with an inner splined sleeve, the inner splined sleeve of the end cover(4) is engaged with a spline on the end of a motor shaft(16), a brake disc(8) of the clasping brake system(9) is fixed on the side of the dragging wheel(1), the brake disc(8) and the dragging wheel(1) are put together on a hollow dragging shaft(7) through an inner embedded bearing(2), the hollow dragging shaft(7) is fixed with the dragging brake machine seat(18), a clasping brake coil and a brake body of the clasping brake system(9) are put together on the dragging machine seat(18).</p> |
