Title:
PERMANENT MAGNET SYNCHRONOUS GEARLESS TRACTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/196501
Kind Code:
A1
Abstract:
Disclosed is a thin type permanent magnet synchronous gearless traction machine, comprising: a holder (1), a stator (3), a rotor (7) and a base (14); a cantilever spindle (11) stretches from a front surface of the holder (1); the spindle (11) extends in a backside direction of the holder (1); the rotor (7) is mounted on the spindle (11); the stator (3) is a concentrated winding and is disposed and fixed on the holder (1); the stator (3) is at the same time located at an outer circumferential side of the rotor (7) to form a radial magnetic field; a traction wheel (5) on the rotor (7) is disposed at one side of the front surface of the holder (1); and a permanent magnet (6) is mounted on an outer surface of the rotor (7) that is adjacent to the stator (3). The machine has small axial dimension, the magnetic pulls of an electromotor in a radial magnetic field are circumferential symmetric and can be offset between each other; and the machine has strong bearing capability, is reliable in operation, and has high efficiency and low noise.
