New energy motor experiment table

Abstract

The invention relates to the field of a motor experiment and aims to provide a new energy motor experiment table. The new energy motor experiment table comprises a base, a motor, an electric dynamometer, a first controller, a second controller, an AC / DC power module, a first DC / DC power module, a second DC / DC module, a coupler, a revolving speed torque sensor and an industrial computer; the motor and the electric dynamometer are fixedly arranged on the base; an output shaft of the motor, the revolving speed torque sensor and an input shaft of the electric dynamometer are successively coaxial connected through the coupler. The new energy motor experiment table has the beneficial effects that the buses of the first DC / DC power module and the second DC / DC module are shared, the harmonic wave of the plant power grid is reduced, the internal recycling of the electric quantity is reduced, the power consumption of the plant is reduced, the dual DC / DC power module is adopted, the power utilization and control of the first controller and the second controller are not mutually interfered and the stability is increased.

Description

technical field [0001] The invention relates to the field of motor experiments, in particular to a new energy motor experiment platform. Background technique [0002] As environmental protection measures around the world become more and more stringent, there are more and more alternatives to fuel engine vehicles, such as hydrogen energy vehicles, fuel cell vehicles, electric vehicles, etc. But at present, the most practical and commercial operation model is electric vehicles. Electric vehicles are increasingly attracting people's attention, and have gradually entered people's lives. However, as an electric vehicle drive system, its powertrain transmission assembly replaces the engine of a traditional vehicle with components such as a motor in the drive chain, so it is extremely important to test the performance and reliability of the motor and motor controller. [0003] With the decline of government subsidies in the new energy industry, manufacturers of new energy systems...
