Abstract

The invention provides an electronic multi-gear variable-speed motor of the electric vehicle and a control system thereof. The electronic multi-gear variable-speed motor of the electric vehicle and the control system are characterized in that a field effect transistor or an IGBT tube is used for controlling switching among different connection modes of three-phase connection mode, six-phase connection mode, star-shaped connection mode, triangular connection mode, polygonal connection mode, serial connection mode, parallel connection mode, single connection mode, single-tap connection mode and double-tap connection mode; the equivalent impedance of a motor winding is changed for realizing gearshift speed change; the electronic multi-gear variable-speed motor is used for a DC permanent-magnet brushless motor which is controlled by a multiphase winding and multiple phase, a DC permanent-magnet synchronous motor, a switched reluctance motor, an AC motor, a main driving motor and a hub motor; wherein a multiphase winding and multiphase control are used in the motors; and through speed control software, in-gear speed control is slowly performed at the end switching part and the starting switching part of each speed gear through speed control software, thereby realizing switching without vibration.

Description

1. Technical field [0001] The invention relates to an electric vehicle and an electric vehicle motor and a control system, in particular to an electric vehicle and an electric vehicle multi-speed variable speed motor and a control system. 2. Background technology [0002] At present, electric vehicles and electric vehicles widely use DC brushless permanent magnet synchronous motors, DC brushless permanent magnet motors, switched reluctance motors and AC asynchronous motors. They essentially adjust the power to achieve speed regulation and torque regulation. The motor needs a large torque during start-up and climbing, which can reduce the speed; normal driving requires a high speed, which can reduce the torque; these all require the realization of electric vehicle gear shifting on the basis of constant total power. The existing motor and control system do not have the function of gear shifting. When starting and climbing, the power is increased to increase the torque; when dr...
