Description

Technical Field

[0001] The utility model relates to the technical field of motor control, in particular to a motor controller. Background Art

[0002] A motor controller is a device or system used to control the operation of an electric motor. It usually includes a series of electronic components, sensors, and software to monitor the operating status of the motor, adjust the speed, direction, and torque of the motor, and ensure that the motor operates within a safe and efficient operating range. Motor controllers can be applied to a variety of different types of motors, including DC motors, AC motors, and stepper motors. In the fields of industry, transportation, and household appliances, motor controllers play a vital role in achieving precise control and regulation of motor operation and improving the performance and efficiency of equipment.

[0003] However, the conventional motor controllers still have many shortcomings. For example, a motor controller disclosed in Chinese patent document CN104780736B uses phase change materials to absorb heat, slowing down the temperature rise and giving the outer surface of the housing more time to dissipate heat, but still has the following technical disadvantages:

[0004] (1) When the motor controller is used for a long time, the electronic components inside the motor controller are easily damaged. When the internal electronic components need to be repaired, it is inconvenient for the staff to disassemble the motor controller, and the disassembly process is cumbersome and inconvenient for the staff to operate;

[0005] (2) When the motor controller is in use, there is no temperature alarm device. Since temperature has a great impact on the motor controller, if the staff is not reminded in time, it is easy to cause damage to the motor controller. Utility Model Content
