Abstract : Global warming and noise pollution are serious ailments plaguing today's world. This paper deals with the electric scooter in which a Brushless DC(BLDC) motor is incorporated at the rear wheel of the scooter. The controlling of BLDC motor is done by a Motor Control Unit(MCU) in which the motor rotates based on current commutation. With the hall sensor outputs at each position of rotor there will be a switching scheme of six different states. Start stop and speed control of vehicle are controlled by the MCU. A 60V,1000W BLDC Motor is selected to drive the vehicle. The mathematical modelling of BLDC motor is implemented in matlab simulink. Also the closed loop speed control of BLDC motor is done in matlab. Hardware control of motor is done using Arduino uno development board in which Atmega 328 microcontroller is embedded. Corresponding pulses are obtained to drive each switch at different commutation states. © Research India Publications.
