reflection paper on medical terminology - Jan 08, · In a BLDC motor, the MCU must know the position of the rotor and commutate at the appropriate time. The speed control can be closed loop or open loop speed control. Open Loop Speed Control – It involves simply controlling the dc voltage applied to motor terminals by chopping the dc voltage. However this results in some form of current limiting. Brushless motors are not self-commutating, and hence are more complicated to control. BLDC motor control requires knowledge of the rotor position and mechanism to commutate the motor. For closed-loop speed control there are two additional requirements, measurement of the motor speed and/or motor current and PWM signal to control the motor speed.
