Abstract

The invention provides a flywheel motor and its controllable pump oil cooling method, which belong to the field of motor technology and flywheel energy storage technology. Rotately and vertically connected in the base, wherein the rotating shaft arranged at the lower end of the flywheel has a hollow cavity with the opening facing downward; the flywheel motor of the present invention makes the rotating shaft into a hollow shaft, through which the oil is sprayed In addition, considering that when the flywheel rotates at a high speed, if the oil pump continues to run, due to the disturbance of the cooling oil, the vibration of the shaft system may increase, instability may occur, and the rotor or bearing may be damaged. In order to control the timing of fuel injection according to the rotation speed of the flywheel, so as to ensure the normal and stable operation of the flywheel motor.

Description

technical field [0001] The invention relates to the technical field of motors and the technical field of flywheel energy storage, in particular to an adjustable pump oil cooling method for flywheel motors. 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 oil cooling...
