Problems solved by technology

However, due to the limitation of the position detection method (such as position sensor (photoelectric sensor) detection), the existing method of starting two phases at the same time is very easy to generate negative torque during start-up, resulting in poor improvement. The starting torque of the switched reluctance power, and the detection accuracy is poor, and the stability is poor

Abstract

The invention relates to a switched reluctance motor and a starting method thereof, and a multifunctional food processer, and the starting method comprises the following steps: obtaining a conduction current when the switched reluctance motor is started; determining a current sector of the switched reluctance motor and a rotation direction of the switched reluctance motor; according to the breakover current, the current sector and the rotation direction, determining a breakover phase of double-phase starting; setting conduction time according to the opening phase and the set rotating speed; and controlling the turn-on phase to be turned on based on the turn-on time and the turn-on phase. According to the switched reluctance motor, the conducting current when the motor is started is detected, and the conducting two phases are determined by combining the position and the rotation direction of the motor, so that the position of the motor rotor is determined through the current to conduct the corresponding two phases, and the purpose of improving the starting torque of the switched reluctance motor is achieved; and the starting performance, the stability and the reliability of the switched reluctance motor are improved.

Description

technical field [0001] The invention relates to the field of motor control, and more specifically, to a switched reluctance motor, a starting method thereof, and a multifunctional cooking machine. Background technique [0002] The switched reluctance motor has good starting performance. In the existing scheme, in order to increase the torque of the switched reluctance motor, a common method is to start two phases at the same time to increase the torque of the switched reluctance motor. However, due to the limitation of the position detection method (such as position sensor (photoelectric sensor) detection), the existing method of starting two phases at the same time is very easy to generate negative torque during start-up, resulting in poor improvement. The starting torque of the switched reluctance power has poor detection accuracy and poor stability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a switched r...
