WebThere are several different methods useful for causing an AC induction motor to brake, or slow down: DC injection Dynamic braking Regenerative braking Plugging DC injection … 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.
