More Information
Summary:The present invention includes an auxiliary coil (20) for the electric machine (16) capable of being accommodated in a two-wheeler or a three-wheeler (11). Said coil is wound around the stator (15) tooth or teeth and voltage induced in the auxiliary coil (20) is used to control the switches (s101, s102) used for winding reconfiguration, thus saves energy and controller modifications. The voltage induced in the coils depends on the speed of rotation for a given number of turns. To operate the reconfiguration switches (s101, s102), the voltage has to be above a threshold which is achieved above a rotational speed. The switches (s101, s102) for reconfiguration are arranged such that they are normally in one configuration giving rise to standard motor speed-torque characteristics, and when energized gives rise to another winding configuration, resulting in changed motor characteristics.
