WebRached Dhaouadi. This paper describes the design and analysis of a regenerative braking system for a permanent magnet synchronous motor (PMSM) drive for electric vehicle (EV) applications. First ... WebSince this motor is rated for 24-Volts, the battery terminal voltage would be 24-Volts. To generate 24-Volts from the motor (or higher voltage), the motor should run at a speed of 3,400 RPM or higher. Hence we have to figure out ways to boost the back EMF generated by the motor so that even at lower speeds, the motor can work as brake.
