The invention discloses a driving method of a reactive type stepping motor. The method comprises the steps that a control signal sent by a controller and a detection signal which is sent by a position detection device and contains real-time position information of a rotor in the reactive type stepping motor are received; whether an actual control speed value of the control signal is smaller than the set control speed value or not is judged, if yes, the reactive type stepping motor is controlled to operate in a pulse mode according to the control signal, and if not, the reactive type stepping motor is controlled to operate in a voltage mode according to the control signal and the detection signal. According to the driving method, the reactive type stepping motor can be not only applicable to a low-speed working environment, but also applicable to a high-speed working environment and can provide larger torque in various working environments, and the applicability of the reactive type stepping motor is improved. The invention further discloses a driver of the reactive type stepping motor and a reactive type stepping motor driving system including the driver of the reactive type stepping motor.
Description
technical field [0001] The invention relates to the technical field of electromechanical control, in particular to a driving method of a reactive stepping motor. In addition, the present invention also relates to a driver of a reactive stepping motor and a driving system of a reactive stepping motor including the above-mentioned driver of a reactive stepping motor. Background technique [0002] The current reactive stepper motor drive system includes components such as a driver, a reactive stepper motor, and a position detection device. The driver, the reactive stepper motor and the position detection device form a closed-loop system. When the reactive stepper motor is running, the pulse signal is received, and the pulse signal is distributed in a ring and the power is amplified, so as to drive the reactive stepper motor winding to be energized in a certain order, and drive the reactive stepper motor to run. Wherein, the position detection device can detect the actual displ...
