Abstract

The present invention relates to a torque position coding device for a brushless motor, comprising a motor position encoder, a controller, a code selector and a PWM drive circuit. The motor position encoder is connected to a motor for measuring the angular displacement of the motor rotor to generate a UVW signal and an ABI signal. The controller is used to estimate the position angle of the motor rotor. The code selector is connected to the UVW signal and ABI signal of the motor position encoder for receiving a switching signal output from the controller when the motor starts, and selecting the UVW signal to be sent to the controller. When the controller judges that the UVW signal is in a specific interval, the code selector receives the switching signal output from the controller and selects the ABI signal to be transmitted to the controller. It can quickly and accurately calculate the current position angle of the motor rotor so that the controller can drive the motor rotor to operate according to the torque control. The PWM drive circuit is connected to an output end of the controller and a stator coil winding of the motor for receiving a torque control from the controller and driving the motor rotor to operate according to the torque control. The UVW signal output from the motor position encoder is to divide a 360-degree rotation of the motor rotor into six sections, each of which is 60 degrees. The UVW signal is set to a commutation point when converted to the specific interval. When the motor starts, the switching control terminal outputs the switching signal to the code selector, and controls the code selector to select the UVW signal to be transmitted to the input end of the controller for reading the UVW signal and judging whether the motor rotor turns to the commutation point.
