Embodiment 1

[0077] Example 1: See Figure (1-4).

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

[0079] Step 2. The stator core winding 125 of the motor / generator is assembled with the hollow shaft 133 of the stator core: the inner circular convex keyway 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 Recessed keyway, press in and lock.

[0080]Step 3. Assemble the two stator core windings 123 of the magnetic suspension bearing motor with the hollow shaft 133 of the stator core: the inner circular convex key grooves of the two stator core windings 123 of the magnetic suspension bearing motor are aligned with the outer circle of the hollow shaft 133 of the stator core The concave keyway is press-fitted and locked, and is placed on the stator core winding 125 of the motor / generator symmetrically.

Embodiment 2

[0091] Example 2: Please refer to Figure (5-6).

[0092] The power controller system of the magnetic levitation flywheel energy storage motor generator assembly has four working modes: energy storage charging mode, energy maintaining operation mode, energy releasing and discharging mode and shutdown mode.

[0093] The ECU control uses a 64-bit computer to receive voltage, current, pressure, Temperature, rotational speed, and rotation angle sensor information; according to this information, the calculated results are transformed and output as control signals, and the comparison and calculated results are used to control the magnetic suspension magnetic force of the magnetic bearing motor and the magnetic bearing disc motor, and the motor / generator required Control of torque, power, pressure and temperature.

[0094] The control core component of the magnetic suspension bearing motor M1, M2, M3 magnetic suspension bearing system is the external power supply HVECU or Sc super ca...

Embodiment 3

[0097] In another embodiment 3: flywheel energy storage and supercapacitor energy storage hybrid electric bus.

[0098] It is mainly composed of three parts: the bus hub drive motor module, the super capacitor energy storage module and the flywheel energy storage module. The hub drive motor is 100 kW, the second set of super capacitor energy storage modules is 16 kWh, and the magnetic levitation flywheel energy storage motor generator set has 96kWh energy storage , each maglev flywheel energy storage motor generator 2kWh is 180mm long, 230 mm in diameter, 23kg in mass, and rotates at 200,000 r / min. A total of 48 maglev flywheel energy storage motor generators weigh 1052 kg in total, and the total energy storage of the flywheel group is 96kWh, placed in the chassis of the bus, can enable the 16-ton flywheel energy storage and supercapacitor energy storage hybrid bus to travel 250 km at a speed of 1000km / h, without the need to set up charging piles at each bus station. It is ben...

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...
