8/6 switched reluctance motor drive

A battery-fed 1.5 kW SRM drive with hysteresis current control and a speed loop.

Rotor speed, torque, phase currents and battery current through a load step
1000 rpm with a 2 → 8 N·m load step
Inductance profile, flux-linkage curves and static torque of the 8/6 SRM
Machine characterisation

Aim

Build a 4-phase 8/6 SRM drive with an asymmetric half-bridge converter, saturating flux-linkage tables, angle commutation and an outer speed loop, then test a load step.

What you’ll learn

  • Inductance and flux-linkage profiles of an SRM, with saturation
  • Asymmetric half-bridge converters and hysteresis current control
  • Turn-on and turn-off angles
  • Speed control through a load step
