SRM energy storage box operation principle

How does a SRM drive system work?

For a SRM drive system to operate and generate energy,\ it must meet three conditions. First, there must be external mechanical energy inputting to the rotor shaft of the motor. Second, the stator winding must be energized in the proper given order to provide excitation.

How does SRM Work?

SRM follows the operation principle that the flux is always closed along the path of minimal reluctance. Tangential force could be generated between the two adjacent stator and rotor poles if the stator pole is excited, and thus reluctance torque is formed smoothly when each phase is turned on and off sequentially.

What is the basic principle of SRM motor?

This is the basic principle of the SRM motor. Consider the phase windings of this stator be AA’, BB’, CC’. When we energized the phase winding A, Then rotor tries to align along with this phase. The A phase will be de-energized and phase B will be energized. Now the router tries to align along phase B.

Why is SRM a good choice for electric drive systems?

As a potential candidate, SRM has high fault tolerance due to its simple structure. The large starting torque, the correspondingly small current, and the ability of four-quadrant operation are suitable for the requirements of the electric drive system.

How does a flywheel storage drive (SRM) Work?

In the variant under consideration, the phases of the SRM are powered by unipolar current pulses [ 16, 17 ]. Each phase is connected to a half-bridge self-commutate voltage inverter (A1 - A3), as it is showed in the Fig. 2. Structural and functional diagram of the control system of the SRM of the flywheel storage drive

What are the structural parameters of SRM?

The structural parameters of an SRM (Switched Reluctance Motor) are listed in Table 1.1. According to these parameters, the finite element model of the SRM is established, as shown in Fig. 1.19. Magnetic flux lines, magnetic density distribution, inductance, mutual inductance, and electromagnetic torque can be obtained by the FEA (Finite Element Analysis).
