Method, apparatus, storage medium and program product for reduced-voltage starting of motor

An apparatus for reduced-voltage starting of a motor, comprising:

• a task module configured to:
• obtain a starting instruction indicating starting of the motor;
• a data processing module configured to:
• determine a line voltage between a first phase and a second phase in a line based on the starting instruction;
• and
• determine a zero-crossing point of the line voltage;
• a control module configured to:
• start a first timing at the zero-crossing point of the line voltage;
• close a first switch of the first phase and a second switch of the second phase in response to the first timing satisfying a first predetermined duration, the first predetermined duration being determined based on the zero-crossing point of the line voltage and closing angle information of the motor;
• start a second timing in response to the first switch and the second switch being closed;
• and
• close a third switch of a third phase relative to the first phase and the second phase in the line in response to the second timing satisfying a second predetermined duration.

A non-transitory computer-readable storage medium having one or more computer instructions stored thereon, wherein the one or more computer instructions are executed by a processor to implement operations comprising:

• determining a line voltage between a first phase and a second phase in a line in response to obtaining a starting instruction indicating starting of the motor;
• determining a zero-crossing point of the line voltage;
• starting a first timing in response to reaching the zero-crossing point of the line voltage;
• closing a first switch of the first phase and a second switch of the second phase in response to the first timing satisfying a first predetermined duration, the first predetermined duration being determined based on at least the zero-crossing point of the line voltage and closing angle information of the motor;
• starting a second timing in response to the first switch and the second switch being closed;
• and
• closing a third switch of a third phase relative to the first phase and the second phase in the line in response to the second timing satisfying a second predetermined duration.
