There is a great demand for efficient, quiet, reliable, and cost-effective motor drives for propulsion systems in hybrid and plug-in hybrid electric vehicles. Owing to a rigid structure and the absence of magnetic source on the rotor, a switched reluctance machine (SRM) is inherently robust and cost effective. In spite of these advantages, several challenges in the control of this machine remain an...
Switched reluctance motor (SRM) drives have gained considerable popularity for automotive, defense and aerospace applications which desire ruggedness, high speed capability, and fault tolerance. In spite of significant progress in the development of advanced control strategies over the past two decades, high levels of torque pulsation and acoustic noise in SRM drives still present a major shortcoming...
This paper discusses a configuration of switched reluctance machine (SRM) that has novel relationship between the number of stator poles and rotor poles. Such a stator/rotor pole combination presents an SRM design with minimal torque ripple, acoustic noise and higher continuous rated power density. Further, the machine topology realizes these attributes while presenting attributes highly suitable...
With an increasing need for energy-efficient automation, majority of applications have sought after innovative solutions that can deliver high-grade performance over a wide range of speeds and can operate under harsh operating conditions. Propulsion and generation systems for vehicular, aerospace, and military applications are some of the typical areas that resent such demands for electric machines...
This paper presents a digital control technique for trapezoidal brushless DC (BLDC) motor drives. This novel digital control treats BLDC motor as a digital system and regulates speed with the help of two predefined state variables, state-1 designed for high-speed operation and state-2 defined for low-speed operation. A comparator compares actual speed with set speed and then switches between appropriate...
