Problems solved by technology

[0002] Electronic pump control circuit boards currently on the market include embedded microprocessors (single-chip microcomputers), motor pre-driver integrated chips, and motor drive circuits independent of motor pre-driver integrated chips. The motor drive circuit is composed of some discrete electrical components. Circuits composed of components, these discrete electrical components occupy a lot of space on the one hand, and on the other hand these discrete electrical components also cause a lot of energy consumption

Abstract

The invention discloses an electronic pump, which includes a controller; the controller includes a power input terminal, a printed circuit board, a motor driver and a single-chip microcomputer; the power input terminal, the single-chip computer and the motor driver are separated by a certain electrical gap and fixedly connected to the printed circuit board respectively, The single-chip microcomputer and the motor driver are electrically connected through a printed circuit; the motor driver drives the motor to rotate according to the driving control signal from the single-chip microcomputer; between the motor driver and the motor, the controller is not provided with discrete components on the printed circuit board for driving the motor to rotate Composed motor drive circuit; the application of the invention saves the setting of peripheral discrete components and reduces energy consumption.

Description

【Technical field】 [0001] The invention relates to an automobile part, in particular to a part of an automobile thermal management system. 【Background technique】 [0002] Electronic pump control circuit boards currently on the market include embedded microprocessors (single-chip microcomputers), motor pre-driver integrated chips, and motor drive circuits independent of motor pre-driver integrated chips. The motor drive circuit is composed of some discrete electrical components. A circuit composed of components, these discrete electrical components occupy a lot of space on the one hand, and on the other hand, these discrete electrical components also cause a lot of energy consumption. [0003] Therefore, it is necessary to improve the existing technology to reduce the power consumption of the water pump control system and improve its reliability and compatibility. 【Content of invention】 [0004] The object of the present invention is to provide an electronic pump with low e...
