Overview Small high-speed BLDC motors have a very low inductance, which is different from conventional BLDC motors. When PWM control is applied to the phases of a small high-speed BLDC motor, the current follows the rectangular PWM voltage shape. This change of current magnetizes and demagnetizes the motor iron at a frequency equal to the PWM frequency, which can cause the motor to become hot enough to be damaged. To prevent this, special techniques are required to control this type of motor. The method used in this reference design consists of a DC/DC inverter that generates the desired voltage for the motor. The motor then uses a conventional 3-phase inverter for commutation.
