Abstract

The invention discloses a motor controller which is used for driving a motor. The motor controller is provided with a driving circuit, a control unit, an operational amplifier, a comparator, an inverter, a multiplexer, a first resistor and a second resistor, wherein the first resistor and the second resistor are arranged on a printed circuit board. The driving direction of the motor can be changed by changing the resistance value of the first resistor and the resistance value of the second resistor.

Description

technical field [0001] The present invention relates to a motor controller, in particular to a motor controller capable of changing the driving direction of the motor. Background technique [0002] A general motor controller includes a Hall sensor, and the Hall sensor is a sensor for measuring the magnitude of a magnetic field based on the Hall effect. Once the circuit structure of the motor controller is determined, the follow-up processing of the Hall signal generated by the Hall effect can only make the motor drive have a single output mode. Contents of the invention [0003] In view of the foregoing problems, the object of the present invention is to provide a motor controller capable of changing the driving direction of the motor. [0004] According to an embodiment of the present invention, a motor controller for driving a motor is provided. The motor controller has a drive circuit, a control unit, an operational amplifier, a comparator, an inverter, a multiplexer,...
