Hide pole self-adapted brushless synchronization electrode rotor winding unit

Abstract

The invention provides a hidden-pole self-adaptive brushless synchronous motor rotor winding which is characterized in that the rotor of a main motor is of a hidden-pole type lower line structure. The invention relates to a special winding that AC and DC can work simultaneously. The winding of the rotor of the main motor consists of five sets of windings, including four sets of three-phase symmetrical AC windings and the fifth set of single-phase DC winding. No electric electronic switch device is arranged in the rotor, the reliability is high. The structure of the motor integrates the four functions of starting, damping, exciting, and compound exciting into one, and causes that the structures of the generator and the motor rotor are uniformed and simplified, and can be used commonly.

Description

The rotor winding of self-adaptive brushless synchronous motor with hidden poles technical field The invention relates to a rotor winding of a brushless synchronous motor, in particular to a rotor winding of a hidden pole self-adaptive brushless synchronous motor. Background technique Coaxial brushless synchronous generators with AC exciters have been widely used, but brushless synchronous motors with similar structures have more complex rotor structures than generators due to starting problems, synchronous problems and stable operation problems, and generally need to increase power electronic switches etc. The cost is increased, the length of the motor is increased, and the reliability is reduced. Brushless synchronous generators and motors of this structure are generally manufactured separately, and are rarely made into universal types. Contents of the invention The purpose of the present invention is to provide a hidden pole self-adaptive brushless synchronous moto...

AI Technical Summary

Problems solved by technology

Coaxial brushless synchronous generators with AC exciters have been widely used, but brushless synchronous motors with similar structures have more complex rotor structures than generators due to starting problems, synchronous problems and stable operation problems, and generally need to increase power electronic switch etc.

Increased cost, increased motor length, reduced reliability

Brushless synchronous generators and motors of this structure are generally manufactured separately, and rarely made into general-purpose ones.
