Problems solved by technology

In the middle and late stages of the life, after the stepper motor has been running for a long time, the output torque required for the normal rotation of the motor will increase due to the volatilization of the solid lubricant and the reduction of the electromagnetic efficiency of the system.
However, it is not possible to fix the output torque of the motor at an excessively high level at the initial stage of orbiting, because although the high torque can ensure that the motor can continue to be driven at the end of its life, it consumes a lot of power and aggravates the vibration and wear of the motor

Abstract

The invention discloses a stepping motor adaptive torque adjusting method based on position closed-loop control. The stepping motor adaptive torque adjusting method comprises the following steps: S1, setting a position sensor to monitor the out-of-step number of a stepping motor in real time; and S2, the control system adjusts a driving pulse of the stepping motor according to the out-of-step number to realize adaptive torque adjustment of the stepping motor. The driving torque can be automatically adjusted according to motor resistance and load change conditions, waste and motor loss caused by using high power are avoided, and the service life of the motor is prolonged.

Description

technical field [0001] The invention belongs to the field of motor control, and in particular relates to a position-based closed-loop control adaptive torque adjustment method of a stepping motor. Background technique [0002] In the initial stage of satellite space operation, the stepper motor drive system has low running resistance and can maintain its normal operation with a small output torque. In the middle and late stages of the life, after the stepper motor has been running for a long time, the output torque required for the normal rotation of the motor will increase due to the volatilization of the solid lubricant and the reduction of the electromagnetic efficiency of the system. However, it is not possible to fix the output torque of the motor at an excessively high level at the initial stage of orbiting, because although the high torque can ensure that the motor can continue to be driven at the end of its life, it consumes a lot of power and aggravates the vibratio...
