Embodiment Construction

[0017] The content of the present invention will be further described below in conjunction with the accompanying drawings, but the practical application structure of the present invention is not limited to the following embodiments.

[0018] Referring to the accompanying drawings, the stand-alone multi-drive multi-winding motor system of the present invention is composed of a parallel multi-winding motor 1 and a driver 2. The driver 2 includes a core controller main board 3 and no less than two independent circuits. Parallel drive units.

[0019] The parallel multi-winding motor in the accompanying drawings of the present invention takes a three-phase asynchronous motor as an example. There are multiple sets of independently working windings arranged in parallel on the stator of the motor. The power connection method of a single winding is consistent with that of a single winding motor. The parallel windings of the motor work independently, and their power supply terminals are...

Abstract

The invention provides a single-machine multi-drive and multi-winding motor system, consisting of a parallel multi-winding motor and a driver, wherein a plurality of sets of mutually-independent windings are arranged on a stator in the parallel multi-winding motor in parallel; the driver comprises multi-path parallel driving units, multi-path parallel output units and a main control unit; the multi-path parallel driving units are used for generating motor driving signals corresponding to motor windings in a one-by-one manner; the multi-path parallel output units are used for monitoring the working state of the corresponding windings and transmitting the driving signals generated by the multi-path parallel driving units to the corresponding motor windings; the main control unit is used for acquiring and analyzing working state monitoring signals of all the windings and the multi-path parallel driving units, coordinating and controlling signal output of all the parallel driving units according to the monitoring signals and realizing parallel driving of different windings. In the single-machine multi-drive and multi-winding motor system, the problem that when a certain winding or driving unit in the existing motor system fails, other windings or driving units cannot work completely is overcome, so that the reliability of the motor is improved. The single-machine multi-drive and multi-winding motor system has the advantages of simple structure, high reliability and fast response and the like.

Description

technical field [0001] The invention belongs to the technical field of motor application and relates to a multi-winding motor system. Background technique [0002] The reliability requirements of equipment (such as armored vehicles, tanks, electric vehicles, etc.) under complex working conditions are very high, so the reliability of the motor system used in the equipment is also put forward higher requirements. The traditional medium and high power system motor drive system often adopts two configuration methods, one is to form a system by a single medium and large capacity driver and a traditional single winding medium and high power motor, and the other is to use multiple small capacity drivers and traditional single Winding medium and high-power motors constitute the system. [0003] In the first method, the driver is directly connected to the motor, and the structure is simple, but because the traditional motor has a single winding structure, the reliability of both the...
