Abstract

The invention provides a motor power generator, which is characterized in that a main power supply circuit of a dual-power-supply converter is connected with a battery pack, and a standby power supplycircuit is connected with a DC-DC step-down constant-current constant-voltage output end; a motor starting power supply is powered by the battery pack and supplies rated voltage to a motor driving module through a boosting module; a motor drives a planetary gear to force the power generator to rotate at an increased speed; a power generator stator winding generates induction current, the currentis connected with the input end of a DC-DC converter through rectification and voltage stabilization, and constant-current and constant-voltage output to a bus standby power supply circuit is realizedthrough DC-DC conversion voltage reduction; when a driving motor reaches a rated rotating speed, the dual power supply is converted into the standby power supply circuit to output rated voltage to the driving motor while the main power supply circuit of the dual-power-supply converter is automatically switched off, and the DC-DC voltage reduction constant-current constant-voltage parallel outputsupplies power to the load motor; and voltage circulation, conversion and recombination of the motor generator are formed.

Description

technical field [0001] The invention relates to the technical field of motors, generators and new energy sources, in particular to a motor generator which becomes a renewable power source. Background technique [0002] The accompanying energy security and environmental pollution are two of the most thorny bottlenecks. Petroleum security, resource shortage, and harmful substances emitted by the exhaust of automobiles during driving damage the environment and human health. [0003] However, electric vehicles have hybrid, plug-in hybrid, fuel cell, pure electric vehicles and other modes, limited by the level of power battery technology and charging technology, there are energy density, cruising range, charging speed, construction of charging stations, etc. Restricting factors have become the bottleneck in the development of pure electric vehicles. In view of this, there is an urgent need for a renewable power source to generate electricity to solve the pollution of the environm...
