Abstract

The present invention discloses a multi-stator rotor structure axial direction permanent magnet brushless traction machine, and relates to the elevator device technology field. The machine comprises a spindle, a plurality of rotor modules fixedly arranged on the spindle and a stator, the stator is arranged between two adjacent rotor modules and there is a gap between the stator and the rotor modules, the stator is a printed circuit board module, the printed circuit board is provided with a plurality of coil sets, the coil sets comprise a 3-phase winding unit, the coiling unit are connected with and connected in series with wires arranged at the inner ring and the outer ring of an internal connection layer of the printed circuit board to form a winding loop, and one end of the 3-phase winding unit is connected in the internal connection layer of the printed circuit board to form neutral points. Through adoption of the structural design, the printed circuit board replaces a traditional metal wire winding to allow the structure of the traction machine to be simpler, effectively reduce the quality of the whole machine, improve the reliability of the work of the traction machine and reduce the elevator load.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to an axial permanent magnet brushless traction machine with a multi-stator-rotor structure. Background technique [0002] The elevator traction machine is the power equipment of the elevator, also known as the elevator host, and its function is to transport and transmit power to make the elevator run. The traction machine is composed of electric motor, brake, coupling, reduction box, traction wheel, frame, guide wheel and auxiliary turning hand wheel, etc. The electric motor is the key component of the traction machine. [0003] In the prior art, there is no significant change in the structure of the motor of the traction machine. The rotor mainly adopts radial pole segmented permanent magnets, and the stator is composed of coils wound in laminated silicon steel sheets. The quality of the laminated silicon steel sheet accounts for about one-third of the total mass of th...
