Example Embodiment

[0077] Example 1: Please refer to Figure (1-4).

[0078] Step 1. The specific assembly step, the overall assembly of the magnetic levitation flywheel energy storage motor generator assembly 115.

[0079] Step 2. Assemble the stator core winding 125 of the motor / generator with the hollow shaft 133 of the stator core: the inner convex key slot of the stator core winding 125 of the motor / generator is aligned with the outer circle of the hollow shaft 133 of the stator core Concave keyway, press in to lock.

[0080] Step 3. Assemble the two stator core windings 123 of the magnetic bearing motor with the hollow shaft 133 of the stator core: the inner convex key slots of the two stator core windings 123 of the magnetic bearing motor are aligned with the outer circle of the hollow shaft 133 of the stator core The concave key slot is pressed in and locked, and placed on the stator core winding 125 of the motor / generator for two symmetrical measurements.

[0081] Step 4. Assemble the stator co...

Example Embodiment

[0097] In another embodiment 3: flywheel energy storage and super capacitor energy storage hybrid bus.

[0098] It is mainly composed of bus wheel hub drive motor module, super capacitor energy storage module and flywheel energy storage module. The hub drive motor is 100 kW, two sets of super capacitor energy storage modules are 16 kWh, and the magnetic levitation flywheel energy storage motor generator set is 96kWh. Each maglev flywheel energy storage motor generator 2kWh is 180mm long, 230 mm in diameter, 23kg in mass, and 200,000 r / min. The total weight of 48 maglev flywheel energy storage motor generators is 1052 kg. The total energy storage of the flywheel group is 96kWh, placed on the chassis of the bus vehicle, can make the 16-ton flywheel energy storage and supercapacitor energy storage hybrid bus travel 250 km at a speed of 1000km / h, eliminating the need for charging piles at each bus station. Conducive to the mobility and popularization of hybrid buses with flywheel ene...

Abstract

The invention discloses a magnetic suspension flywheel energy storage motor generator, which is provided with an integrated disposable heat dissipation system of a vacuum shell, a flywheel, a rotor, astator core, a stator shaft and an auxiliary bearing, under the condition of not depending on an external power supply, flywheel energy storage is operated in a standby mode and a power generation mode to supply power to a magnetic suspension bearing, so that a flywheel rotating shaft is self-suspended, and independent operation and transportation transfer of flywheel energy storage are facilitated; the turbine vane pump rotor self-vacuumizing device reduces the energy consumption of a flywheel energy storage system, and the power density of the flywheel energy storage system is improved.

Description

technical field [0001] The invention belongs to the technical field of flywheel energy storage motors, generators and new energy sources, and relates to a magnetic levitation flywheel energy storage motor generator. Background technique [0002] Trains and automobiles, this kind of vehicle is driven by a mixture of internal combustion engine and electric motor, and the flywheel battery is charged quickly and fully discharged, which is very suitable for vehicles driven by hybrid energy. The flywheel battery is charged when the vehicle is in normal operation and braking, and the flywheel battery provides power to the vehicle during acceleration or climbing to ensure that the vehicle runs at a stable and optimal speed, which can reduce fuel consumption. Consumption, air and noise pollution, engine maintenance, extending engine life. [0003] Supercapacitor energy storage buses are driven by on-board capacitors, and the mileage of a 30-second "second charge" charge is only 8-10...
