Flywheel energy storage disc type motor structure

A flywheel energy storage device is a new energy storage device. A motor is the key component of a flywheel energy storage device. The motor has the following strict technical requirements: 1, the motor can store energy and discharge adjustable direct-current electric energy in a simple mode; 2, storage time should be short, and energy loss should be small, when the motor discharges energy, the speed of energy discharge should be slow, so that the energy can be economized and used for a long time, and energy consumption should be extremely small; 3, the structure of the motor is simple, and the motor is convenient to use and maintain, and the motor is suitable for the elderly and juveniles; and 4, the motor is durable and reliable, and has a long service life. The invention provides two kinds of flywheel energy storage device motor schemes, namely, a disc type double-phase and double-speed squirrel cage motor (see Figure 1) which is applicable to a sinusoidal wave variable-frequency power source, and a disc t
