Abstract

The vehicular motor for starting and producing electricity consists of stator, rotor, windings and drive controlling circuit. It features the rotor iron core comprising symmetrical permanent magnet with 2 or 3 pairs of slot wedge holes, cage-shaped winding guide strip, non-magnetic inner ring and shaft hole structure. The guide strip serves as starting winding for the starter, and the permanent magnet provides DC magnetic field to interact with the alternate magnetic field of the stator winding to produce torque. During producing electricity, the permanent magnetic rotor provides exciting magnetic field. The drive controlling circuit includes great-power switching transistor, inverter circuit, triphase bridge rectifier and automatic igniting switch. The vehicular motor is simple in structure and universal, has great output power and can prolong the service life of accumulator.

Description

technical field [0001] The invention relates to a starter and generator multiplexing motor for a vehicle. Background technique [0002] At present, the starting system and power generation system of a car are started and generated by their own motors respectively. The above-mentioned device has the following disadvantages: 1. The existing power supply system can only provide 1-2KW and a single 14V output voltage, which affects the power of the vehicle; 2. The two types of motors form separate systems, making the mechanical structure complex and the failure rate high , Difficult to maintain; 3. Poor versatility, unable to adapt to various models of cars; 4. Close to the engine, high ambient temperature. Contents of the invention [0003] The invention provides a starting and generating multiplex motor for a vehicle, which can solve the problems of high power and multi-level voltage power supply, integration of starting and generating, and universality. [0004] The invent...
