Problems solved by technology

At present, most motor manufacturers use a special test board to communicate with the motor to calculate the angle of rotation after the motor is installed, and then perform zero calibration by changing the parameters of the software. This method is extremely unfavorable to the motor. mass production

Embodiment Construction

[0014] Such as figure 1 As shown, install the resolver rotor 2 on the motor shaft 1, such as figure 2 As shown, the resolver stator 3 is installed on the motor end plate 5 through the pressure plate 4, the resolver stator is provided on the pressure plate, and the threaded hole for fixing the resolver stator and the motor end plate is provided on the pressure plate, the The set screw is tightened so that the resolver stator can turn.

[0015] Decode the output signal of the resolver, output the decoded rotor position signal to the data analysis equipment, compare and process the back electromotive force waveform output by the motor to obtain the rotor phase difference that needs to be compensated, and input the difference to the fork motor After adjusting the position of the resolver stator through the fork motor, tighten the screws to fix the rotating stator and complete the zero point calibration of the motor.

Abstract

The invention relates to a rotation motor zero calibrating method for hybrid and electric automobile, suitable for batch production of motors. The rotation motor zero calibrating method for hybrid and electric automobile is characterized in that: a rotation rotor is mounted on a motor axle and a rotation stator is mounted on the end plate of the motor and then pre-screwed up; the difference value of the two signals are input into a shifting yoke motor, after detecting the motor rotor position signal and the motor stator position signal and the rotation stator is rotated by the shifting yoke motor to perform the difference value compensation and then the rotation stator screw is screwed up and fixed to calibrate the motor zero.

Description

technical field [0001] The invention relates to a method for calibrating the zero point of a resolver motor used in hybrid power and electric vehicles. Background technique [0002] In recent years, due to energy shortage and environmental pollution, the development of the automobile industry has encountered unprecedented challenges. In order to solve these two major problems, the development of a new generation of clean and energy-saving vehicles has become an inevitable trend. Therefore, major automobile manufacturers have participated in the research and development of hybrid and pure electric vehicles, so that motors have been widely used in automobiles. [0003] Due to the obvious advantages of simple structure, reliable operation, small size, light weight, and flexible shape and size, permanent magnet synchronous motors have become the first choice for vehicles. The permanent magnet synchronous motor needs to detect the position of the motor rotor in real time, inclu...
