Abstract

The invention provides an air-cooled motor loss separation device and a loss separation method thereof. The device comprises a wind speed detector and a wind temperature detector which are arranged ina motor ventilating duct, a laser and a sonic sensor which are respectively arranged on the inner side and the outer side of a stator slot wedge, a current detector and a voltage regulator which areconnected with a phase winding of a stator, and an analysis device and a display which are arranged on a motor shell, and the wind speed detector, the wind temperature detector, the laser, the sonic sensor, the current detector, the voltage regulator and the display are all connected with the analysis device. Various losses of the air-cooled motor can be measured through the separation device andseparated according to the loss separation method, the accuracy of loss measurement is improved, the loss measurement period is shortened, and an objective basis can be provided for design of an air-cooled motor cooling system.

Description

technical field [0001] The invention relates to the technical field of air-cooled motors, in particular to an air-cooled motor loss separation device and a loss separation method thereof. Background technique [0002] With the vigorous development of the motor industry and people's pursuit of high efficiency and high precision, the industry requires that the measurement methods of various losses of motors be as accurate as possible. The precise separation of the various losses of the motor can provide a theoretical basis for the derivation of the various loss formulas of the motor, and can also provide an objective basis for the design of the cooling system, thereby improving the problem of excessive temperature rise of the motor. [0003] At present, the measurement and separation of various losses of the motor are inseparable from the thermocouple. The limitation of this method is that it can only measure the water-cooled motor, because the thermocouple is directly attache...
