Abstract

The invention discloses an oil-cooled motor for calibration test, which comprises a casing, a stator and rotor assembly arranged in the casing, and a front end cover and a rear end cover which are in sealing connection with the casing, and is characterized in that a plurality of screw type temperature sensors are distributed on the cylindrical surface of the casing; the front end cover and the rear end cover are respectively provided with a hollow area, and the front end cover and the rear end cover are respectively provided with a transparent cover plate through screws. A stator oil inlet nozzle is assembled at a position above the front end cover, and a plastic insert is arranged in an inner hole of the stator oil inlet nozzle; a bearing oil inlet nozzle is assembled right above each of the front end cover and the rear end cover; and an oil return nozzle is assembled right below each of the front end cover and the rear end cover. In the performance calibration test process, the oil injection effect of the stator and the liquid level height of the bottom of the motor can be visually observed through the hollowed-out areas on the front end cover and the rear end cover, the inner diameter of the oil inlet hole can be adjusted by replacing the plastic insert, the flow pressure of an oil way of the stator can be adjusted, and detection is convenient.

Description

technical field [0001] The present invention relates to the technical field of motors, and more specifically, relates to an oil-cooled motor used for calibration testing. Background technique [0002] The motor will generate a lot of heat during continuous operation. If the temperature of the motor is too high, it will affect the reliable operation and performance of the motor. At present, the cooling methods of drive motors are mainly divided into two methods: water cooling and oil cooling. Compared with water cooling motors, oil cooling motors have many advantages: high cooling efficiency, the cooling medium is in direct contact with the heat source, eliminating hot spots; good insulation performance, no cooling oil Conductive, non-magnetic, and does not affect the electromagnetic field characteristics of the motor; good thermal stability, compared with water, oil has a higher boiling point and lower freezing point, is not easy to change phases, and has a wider application...
