Embodiment Construction

[0027] See Figure 1 and Figure 2, each single-phase rotary transformer is composed of a stator part (stationary) 1 and a rotor part (rotating) 2, the stator part 1 is composed of a stator core 3 and a stator winding 4, and the rotor part 2 is composed of a rotor core 5 and rotor winding 6. Its structure and principle are as follows: the closed iron core 7, primary winding 13 and secondary winding 14 of an ordinary single-phase transformer are divided into two parts in the form of an air gap 10, and one part is the primary winding 13 and the core 8. Part of it is the secondary winding 14 and the iron core 9. Under the premise of maintaining the working principle of the transformer, it is deformed according to the form of the motor stator and rotor. The iron core 9 is transformed into the rotor core 5, the secondary winding 14 is transformed into the rotor winding 6, and the iron core 8 is transformed into The stator core 3, the primary winding 13 is transformed into the stator w...

Abstract

This invention relates to alternating synchronous motor, alternating coil rotor motor and its adjusting device based on three phase rotation transducer in machine process and power electrical technique field, which comprises the following parts: three phase rotation transducer fixed on the motor socket inner axis or motor shell outer axis between static three phase alternating power and motor rotation rotor to send power to take place of original slide ring and brush. This invention alternating synchronous motor and its adjusting device realizes transducer speed adjusting.

Description

technical field [0001] The invention relates to a novel, brushless AC synchronous motor and an AC winding rotor motor, belonging to the field of motor manufacturing. Background technique [0002] Early DC excitation AC synchronous generators and synchronous motors with brushes and slip rings, DC generators and motors with brushes and commutators, and AC wound asynchronous motors with brushes and slip rings. Because of the reasons for the direction device, there are large maintenance workload, poor reliability, and lack of electric sparks. It is a model that is phased out. [0003] Now brushless AC synchronous generators have been widely used. The main structure and principle of the brushless AC synchronous generator is to install a set of DC windings on the stator to generate a magnetic field with a constant size and direction, and to install a three-phase AC winding on the rotor. Since the rotor rotates at a synchronous speed, the rotor on the The three-phase AC winding o...
