Two quadrants control of the switched reluctance motor drive for application in electric drive bicycle

The paper presents the principles of two quadrants control, such as the traction control and regenerative braking control. The configuration of the switched reluctance motor drive for an electric drive bicycle, the schematic diagram of the system, the motor, the rotor position detector, the control logic for the operation at two quadrants and the two quadrants control scheme, are given. A comparison is given of the two types of the three-phase motors, such as the 12/8 and 6/8 structure motors, at the same average electromagnetic torque in the turn numbers of per stator pole coil, the resistance of the stator phased windings, and the basic output frequency of the power converter. Tested results of the developed prototype with the three-phase 12/8 structure motor, in the travel course with once charging, in the velocity, in the output torque, in the output power, in the systematic efficiency and in the peak value of phase current, are presented.
