Abstract

The invention provides a motor balance control method and system, and relates to the field of motor balance. The method is applied to a multi-motor system. The multi-motor system comprises a first motor and a second motor; the Hall interrupt numbers of the first motor and the second motor are acquired, and an absolute value of a difference value of the Hall interrupt numbers of the first motor andthe second motor is calculated, so that whether the rotation between the first motor and the second motor is different or not can be known; the absolute value of the difference value is compared witha preset threshold value, so that whether the motion states of the first motor and the second motor on respective tracks can be balanced or not can be obtained; and if the motion states of the firstmotor and the second motor are not balanced, the current frequency of the first motor and the current frequency of the second motor are adjusted, so that the first motor and the second motor tend to rotate synchronously, the motion trails of the first motor and the second motor on the respective tracks tend to be parallel, and the multi-motor system can be in a motor balance state.

Description

technical field [0001] The present disclosure relates to the technical field of motor balance, in particular, to a motor balance control method and system. Background technique [0002] The balance control of the motor is between multiple motors. Since the speed of each motor is different, the movement conditions between the motors are also different, so it will cause the imbalance of multiple motors in the process of motion. [0003] In the prior art, a current frequency threshold is given to all motors, and when the current frequency of one or more motors is greater than or less than the current frequency threshold, the current frequency of one or more motors is adjusted so that the current frequency tends to Current frequency threshold, so as to achieve a balanced motion state among multiple motors. [0004] However, due to the influence of problems such as the load of each motor and the friction of the internal rotor of the motor, when the current frequency of each moto...
