Technical Field
The utility model belongs to the technical field of the oil pump motor is used, concretely relates to three-phase asynchronous motor.
Background
The oil pump is a light and compact pump, and has three major types, i.e., an in-line type, a distribution type and a single type. The oil pump can be operated only by a power source, and a camshaft at the lower part of the oil pump is driven by a crankshaft gear of the engine.
An Electric machine (also known as "motor") refers to an electromagnetic device that converts or transmits Electric energy according to the law of electromagnetic induction. The motor is represented by a letter M (old standard is represented by a letter D) in a circuit, the motor mainly plays a role of generating driving torque and serving as a power source of electrical appliances or various machines, the generator is represented by a letter G in a circuit, and the generator mainly plays a role of converting mechanical energy into electric energy.
A three-phase asynchronous motor is a kind of induction motor, and is a kind of motor powered by 380V three-phase alternating current (phase difference of 120 degrees) which is simultaneously switched in, and because the rotor and the stator of the three-phase asynchronous motor rotate in the same direction and at different rotation speeds, and have slip ratio, the motor is called a three-phase asynchronous motor.
The three-phase asynchronous motor for the oil pump with the existing structure has low power, high noise and unstable operation, and can not meet the high-standard use requirement of the oil pump.
Based on the problem, the utility model provides a three-phase asynchronous motor.
