Double-stator variable frequency speed regulation asynchronous motor

Abstract

The invention provides a double-stator variable frequency speed regulation asynchronous motor and solves the problems that a current load motor used for a testbed is large in power and wide in constant power range. The motor is a dual independent coil, namely independent stators and independent rotors, the independent stators and the independent rotors share a motor seat, double overhead draught fans force ventilation and cooling, an ejection wire box structure is used in common, import bearings are adopted, a velocity measurement encoder is installed at the non-transmission end of the motor, and the motor bearings and the coil are each provided with a temperature sensor. According to the motor, by selecting the electromagnetism parameters and mechanical structure of the motor reasonably, the requirements of large power (2 * 1200 kW) and wide constant power range (41.6 - 106 Hz) are satisfied, the load capacity of the motor at a high velocity section is improved, the operating environment requirements of the experimental motor are satisfied, and relevant technological standards of the asynchronous motor are satisfied. The motor has a certain potential market, and by referring to the designing and manufacturing experience of the motor, certain economic benefits can be obtained by applying the experience to other fields.

Description

technical field [0001] The invention relates to an asynchronous motor with large power and wide constant power range, in particular to a double-stator asynchronous motor with frequency conversion and speed regulation. Background technique [0002] At present, the load motor equipped in the HXD2C electric locomotive electric transmission joint debugging test station has certain defects. The load motor reduces the test capacity of the test bench, the test preparation process is cumbersome, the space of the test bench is limited, and the equipment manufacturing cost is high.
