Problems solved by technology

Although the use of an external drive circuit board for the motor can effectively improve the working environment of the circuit board and facilitate the improvement of product functions, however, the control box of the controller is usually a closed structure, resulting in the inability of the internal power devices of the controller to perform good heat dissipation. And then affect the service life of the drive circuit board

Abstract

The invention discloses a motor driving controller and a direct-current pump with the motor driving controller; the motor driving controller comprises a controller box and a motor circuit board positioned in the controller box; the controller box comprises a box body and a box cover; an inlet port and an outlet port electrically connected with the motor circuit board are arranged on the side wallof the box body; the motor driving controller further comprises at least one power device arranged on the lower surface of the motor circuit board; a lug boss corresponding to the power device is arranged on the inside surface of the bottom of the box body; and the surface of the power device is appressed to the lug boss. The controller is specifically connected with the controller box through thepower device in the circuit board; the controller box is used as the radiator of the power device; the heat dissipation effect of the power device is effectively ensured; and the service life of thecircuit board is prolonged easily.

Description

technical field [0001] The invention relates to the technical field of fluid control, in particular to a motor drive controller for driving and controlling a DC pump and a DC pump provided with the motor drive controller. Background technique [0002] Traditional water pumps are mainly direct-driven AC pumps. AC pumps need to be equipped with frequency converters or change the power supply voltage to achieve speed regulation. Compared with DC pumps, it is easier to operate while greatly improving efficiency. Realize precise and fast control. [0003] In actual use, many DC pumps are used in high-temperature environments, such as pumping high-temperature liquids, etc. When DC pumps are used in high-temperature environments, the heat in the high-temperature environment will be conducted to the drive circuit board through the motor, plus The heating of the controller power device itself makes the components on the circuit board work in a high temperature environment. Although...
