Embodiment Construction

[0013] Such as figure 1 , figure 2 shown. Both the main motor 19 and the auxiliary motor 18 are variable frequency speed-regulating motors for automobiles, which can be three-phase AC permanent magnet synchronous motors, or three-phase AC asynchronous motors or vehicle frequency conversion speed-regulating DC motors, such as YCVF series automobiles. Speed-regulating three-phase AC asynchronous or permanent magnet synchronous traction motor, only the power of the main motor 19 is greater than the power of the auxiliary motor 18, and the number of poles is different. The main motor 19 is composed of a rotor 20, a stator 8, a casing 4, a front cover 3, a bearing 21, an encoder 2, and a motor shaft 22, and the outer end of the motor shaft 22 is provided with a connecting flange 1. The auxiliary motor 18 is composed of a rotor 17 , a stator 9 , a casing 13 , a rear end cover 14 , a bearing 16 , an encoder 15 , and a motor shaft 22 . The main motor 19 and the auxiliary motor 18 ...

Abstract

The invention provides an on-board generator motor, belonging to the technical field of automobile generator motors. The generator motor mainly solves the problems that the existing generator is not directly connected with the rotation part of an engine in the axial direction and uses a single generator only, therefore, the generation efficiency is low and the generator capability is small. The on-board generator motor is mainly characterized in that the on-board generator motor comprises an on-board variable frequency and adjustable speed main motor and an on-board variable frequency and adjustable speed auxiliary motor, both of which consist of a rotor, a stator, a shell, an encoder and a motor shaft and commonly use the same motor shaft; the shell of the main shell is directly fixedly connected with the adjacent end of the shell of the auxiliary motor; the external end of the motor shaft at the main motor side is provided with a connecting flange. The on-board generator motor has the advantages of high power generation efficiency, reasonable layout structure, large capability of the generator, large power output and generation capability, being able to output by superposing the engine power, and is mainly used for automobile generator motors which are arranged on electric vehicles and used by matching with the automobile engine.

Description

technical field [0001] The invention belongs to the technical field of automobile motors and generators. Specifically relates to a vehicle generator motor which can be axially connected with the rotating parts of the vehicle engine and can be used not only as a generator but also as a motor. Background technique [0002] Existing automobile alternator is connected with engine by belt pulley. Since the generator is not axially directly connected with the flywheel of the engine, it has the disadvantages of low power generation efficiency, easy damage to the belt, small generator capacity and unreasonable structural layout. The Chinese utility model patent has announced a motor for hybrid electric vehicles. The motor for the vehicle is a variable frequency speed regulating motor for vehicles composed of a rotor, a stator, a casing, an encoder and a motor shaft protruding from both ends. The motor shaft of the motor is a motor spline shaft protruding from both ends, and spline...
