Abstract

The invention provides a motor starting buffering method. In the method, a solenoid drive rotating fluid self-modulation resistor is adopted. The method is characterized by mainly comprising a containing cavity, a conducting liquid, a magnetic field, a first resistor body and a second resistor body. The containing cavity is filled with the conducting liquid, and the volume of the conduction liquid is lower than the effective volume of the containing cavity; the first resistor body is located in the center of the containing cavity and makes contact with the conducting liquid, and the first resistor body is partly exposed to the interior of a spare cavity body of the containing cavity; the second resistor body is located in the containing cavity, and makes contact with the conducting liquid; the first resistor body and the second resistor body form an electrical closed circuit through the conducting liquid; the magnetic field has a component in the direction perpendicular to the liquid surface of the conducting liquid between the first resistor body and the second resistor body. According to the motor starting buffering method, the structure is simple, the solenoid drive rotating fluid self-modulation resistor is not prone to damage, the cost is low, and the solenoid drive rotating fluid self-modulation resistor is durable.
