Induction motor drive for battery vehicle
A 9 phase transistor inverter fed induction motor for a battery vehicle with direct wheel drive is discussed. A new method of motor voltage control by pulse, width modulation, where the phases are interlaced in a manner to conserve continuity of the supply current, is described. In addition to …

Vector controlled induction motor drive systems
Over the years, dc motors have been widely used for variable speed drives for numerous industrial applications despite the fact that ac machines are robust, less expensive, and have low inertia rotors. The main disadvantage of the ac machines is the complexity in control and the cost of the related …
