Abstract

An electromagnetic field shield system of a motor controller of an electric automobile is provided with a plurality of power supply surge protectors and signal line protectors and control line protectors mounted in an external layer shield body. Currents sensed by an external strong electric field on the external layer shield body of the motor controller of the electric automobile, power lines, signal lines and a cooling water tank are unloaded and absorbed, so that electronic devices in the motor controller of the electric automobile are not destroyed by the external strong electromagnetic field, and the electric automobile is protected to be safely driven at a high speed according to a design demand. A cooling water cooling system can keep the temperature of the motor controller of the electric unchanged when the electric automobile climes continuously or runs under a large load. With the above technologies, the electric automobile has part technology base which can be popularized. After wide popularization, the electric automobile can replace the prior automobile taking gasoline and diesel as fuel, so that the environment pollution can be treated thoroughly.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an electromagnetic field shielding system for an electric vehicle motor controller that prevents the electric vehicle motor controller from being interfered by an external strong electromagnetic field. Background technique [0002] 1. In electric vehicles, the motor controller is the key component to realize the DC power supply of the battery and the AC power conversion of the motor, and realize the driving operation of the motor. It belongs to the core power component of the electric vehicle, and it must be able to operate continuously and reliably. There are many types of motor controllers, but the layout structure is similar, and there are some problems in reliability and durability verification, such as poor heat dissipation of the drive module, which affects the life of IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) and The overall efficiency of t...
