Abstract

The invention provides a flywheel motor and an adjustable and controllable pump oil cooling method thereof, and belongs to the technical field of motor technology and flywheel energy storage, wherein the flywheel motor comprises a base and a flywheel; the interior of the base is suitable for keeping vacuum; and the two ends of the flywheel are rotatably and vertically connected into the base through rotating shafts, wherein a hollow inner cavity with a downward opening is formed in the rotating shaft arranged at the lower end of the flywheel. According to the flywheel motor, the rotating shaft is made into the hollow shaft, and the temperature of the shaft system is reduced by spraying oil into the rotating shaft; moreover, in consideration of the problems that when the flywheel is at a high rotating speed, if an oil pump continues to operate, due to the disturbance effect of cooling oil, shafting vibration is possibly increased, instability occurs and a rotor or a bearing is damaged, the oil spraying time is controlled according to the rotating speed of the flywheel, and thus normal and stable operation of the flywheel motor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of motors and the technical field of flywheel energy storage, in particular to a flywheel motor and an adjustable pump oil cooling method thereof. Background technique [0002] In order to reduce the friction loss during the operation of the flywheel energy storage system shaft system, a certain degree of vacuum is usually maintained in the flywheel sealed housing. [0003] However, this prevents the heat generated by the flywheel motor from being transferred out through convection, but can only be dissipated in the form of heat radiation, thus causing the motor shaft temperature to be too high during high-speed, high-power operation. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the shafting temperature of the flywheel motor in the prior art is too high, so as to provide a flywheel motor and its controllable pump oi...
