Abstract

The invention provides an electric driving device having a current equalizing function, and electrical equipment. The electric driving device is arranged in the electrical equipment and is used for driving the electrical equipment. The electric driving device comprises a multiphase motor, a direct current (DC) power supply, a command sending part, a current sensor, an output sensor, a controller, a driver and a power converter, and is characterized in that a winding of the multiphase motor is provided with j multiphase winding units which are independent of one another; the power converter is provided with j power conversion units which are respectively connected with the j multiphase winding units in a way of one-to-one correspondence and are independent of one another; the controller comprises j control units which are used for outputting motor control signals and are independent of one another; the driver is provided with j driving units which are respectively connected with the j power conversion units and are independent of one another; j is a positive integer greater than 1.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to an electric driving device and electric equipment with a current equalizing function. Background technique [0002] In today's society, the requirements for environmental protection are getting higher and higher, and the environmental protection standards of various equipment are also increasing. In order to better protect the environment, the state has issued various policies and vigorously promoted new energy and renewable energy. [0003] At present, using electric energy as the driving force of various equipment has become the mainstream of equipment development. Electric equipment such as electric vehicles and electric forklifts that use electricity as energy are increasingly favored by manufacturers and consumers. Electric equipment not only has less pollution and can provide electric energy through renewable energy, but also has the advantages of high energy utilization...
