Embodiment Construction

[0051] The controller of the oil pump motor refers to the control of the oil pump motor. It mainly uses computer programming to control the motor to make it work according to the set direction, speed, angle or response time. The inventor of the present invention found that, on the one hand, although there are many differences in the hardware form of the controller of the oil pump motor, the controller of the oil pump motor with a simple structure and easy operation is rare.

[0052] Software algorithms play an important role in motor control. Therefore, for the controller of the oil pump motor, the research and development of the controller of the oil pump motor with an efficient speed measurement algorithm and logical operation processing software is an important achievement obtained by the inventors of the present invention in their work.

[0053]The present invention is described in detail below, and examples of embodiments of the present invention are shown in the accompan...

Abstract

Embodiments of the invention provide a control method, a controller and a control system for an oil pump motor. The controller of the oil pump motor includes: a rotational speed sensor, a temperature sensor, a memory, a control box and at least two control switches. This control method mainly compares the obtained oil temperature value and rotating shaft speed value with the preset oil temperature reference standard and rotating shaft speed reference standard respectively, and determines the theoretical target state of the oil pump motor according to the comparison results. The corresponding state control value is output to control the operating state of the oil pump motor to be consistent with the theoretical target state. Using this method, the controller of the oil pump motor can collect temperature signals completely independently of the main control, and accept the speed signal input by the speed sensor, and control the corresponding control switch and contactor to achieve a good technical effect of controlling the operation of the oil pump motor.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular, the invention relates to a control method, a controller and a control system of an oil pump motor. Background technique [0002] As the main power equipment, the pump motor is usually used to drive pumps, fans, compressors and transmission machinery. The motor controller is an integrated circuit that controls the motor to make it work according to the set direction, speed, angle or response time. At present, the integrated motor controller is common in the market, and the controller of the gear oil refueling pump motor independent of the main control has not been found yet. At present, in the field of electromechanical control technology, on the one hand, most of the motor speed measurement hardware uses a rotary encoder, that is, the rotary encoder is used to measure the speed and cooperate with PWM (Pulse Width Modulation Technology) to adjust the speed. The ha...
