Twisted Coil Structures for Switched Reluctance Motor Efficiency

The patent applies parameter changes by twisting the wire strands within the coil windings. This physical transformation of the conductor structure modifies electrical parameters such as reducing skin effect and proximity effect, thereby improving electrical efficiency at higher frequencies while maintaining current carrying capacity. The twisting parameter change allows the same coil to perform effectively across a broader frequency range.

The wire twisting parameter change reduces eddy currents and inter-strand circulation within the coil, which are sources of heat generation. By modifying the physical structure of the conductor through twisting, the patent reduces resistive heating effects while maintaining the ability to carry high current, thus resolving the contradiction between current capacity and thermal management.

The patent implements wire twisting during the coil manufacturing process, which is a relatively simple parameter change that can be integrated into existing winding equipment. This twisting modification significantly reduces copper losses and eddy currents by altering the current distribution within the coil, thereby improving electrical efficiency without requiring complex manufacturing process changes.

The wire twisting parameter change creates a coil structure that performs well across a broad spectrum of operating conditions. The twisted configuration reduces frequency-dependent losses, allowing the motor to maintain high efficiency whether operating at low speeds with high current or at higher speeds with lower current, thus expanding the effective operating range of the motor.
