Abstract

The embodiment of the invention, which relates to the field of automatic control, discloses a self-learning method of a motor pole-pairs number and a driver. The method comprises: a motor rotor is rotated to be at a 0-degree electric angle position by field oriented control (FOC); a fixed electrical angle value is given to the motor at the 0-degree electric angle position, so that the motor rotorshakes in a reciprocating manner at the 0-degree electric angle position according to the fixed electrical angle value; according to the fixed electrical angle value and the number of times of reciprocating shaking of the motor, a total electric angle value is calculated, and a total mechanical angle value is calculated according to a mechanical angle that is fed back by an encoder when the motorshakes in a reciprocating manner to the fixed electrical angle value each time; and on the basis of the total electric angle value and the total mechanical angle value, the motor pole-pairs number isobtained. Therefore, even when the motor pole-pairs number can not be obtained from a motor production manufacturer, learning is carried out automatically by the driver to obtain the pole-pairs numberof the motor, so that the motor obtains an optimal output effect successfully.

Description

technical field [0001] The embodiments of the present invention relate to the field of automation control, and in particular to a method for self-learning the number of pole pairs of a motor and a driver. Background technique [0002] Field Oriented Control (FOC) technology is a mathematical transformation method used in the field of DC motor and AC motor control. Because FOC has the potential to improve control performance and reduce energy consumption, it has increasingly become the focus of the motion control industry. The FOC technology is superior to the standard trapezoidal wave commutation technology of the brushless DC motor based on the Hall sensor, and can provide a wider speed regulation range for the motor through a more complex and advanced sine wave commutation technology. When the FOC technology is applied to the motor, it is necessary to know the electrical angle of the motor rotation, so that the d-axis excitation component and the q-axis output component i...
