Description

Technical Field

[0001] The utility model relates to the technical field of motor drive controllers, in particular to a high-efficiency motor drive control device. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It can be divided into DC motors, asynchronous motors and synchronous motors according to its structure and working principle. A high-efficiency motor is a motor with higher efficiency, and its efficiency should meet the relevant energy efficiency level requirements. A high-efficiency motor needs to be used in conjunction with a drive control device.

[0003] Publication No. CN 206948232 U discloses a motor drive control device, including a housing and a control mainboard built in the housing, with aluminum substrates disposed on both sides of the control mainboard, the aluminum substrates sequentially including an aluminum layer, an insulating layer and a copper layer, the copper layer being disposed inwardly, and a plurality of power tubes being distributed on the copper layer; the aluminum layer being disposed outwardly and attached to the inner side of the housing. The device has good heat dissipation effect, high efficiency and simple production.

[0004] However, the drive control device has the following shortcomings: when in use, the device can improve its overall heat dissipation effect by means of multiple aluminum substrates distributed on the outside of the shell. However, since multiple control mainboards are often installed in some shells to drive multiple high-efficiency motors, this causes more heat to be dissipated inside the shell. The heat dissipation effect of the mainboard itself cannot meet the heat dissipation requirements, and the control mainboard is prone to overheating, which affects its service life.

[0005] Therefore, the utility model provides a high-efficiency motor drive control device to solve the above problems. Utility Model Content
