Abstract

The invention discloses a motor controller, and relates to the technical field of controllers, the motor controller comprises a protection box and a transmission belt, the inner cavity of the protection box is fixedly provided with a motor controller body, the top of the protection box is hinged with a sealing cover, the top surface of the sealing cover is provided with an upper heat exchange hole, and the inner cavity of the upper heat exchange hole is provided with a first filter screen; and the top surface of the first filter screen is flush with the top surface of the sealing cover. According to the motor controller, the motor controller body is protected through the protection box and the sealing cover, dust is prevented from falling on the surface of the motor controller body to affect heat dissipation of the motor controller body, and in addition, the joint of the motor controller body and a data connecting line on a new energy automobile is arranged in an inner cavity of the protection box; according to the motor controller, the problem that a joint of the data connecting line and the motor controller body is arranged outside, moisture in humid air easily enters the joint, and faults are brought to the joint is solved, and the working quality of the motor controller is improved.

Description

technical field

[0001] The invention relates to the technical field of controllers, in particular to a motor controller. Background technique

[0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technologies and new structures. With the continuous maturity of new energy vehicle technology, new energy vehicles driven by electricity can be seen everywhere. The new energy vehicles driven by electricity use electric power to drive the motor to rotate, and the motor drives the vehicle to drive. The controller controls the operation of the motor.

[0003] The motor controller on the existing new energy vehicles has no protective measures outside, and the dust attached to the surface will affect its heat dissipation ef...
