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.

Overview The reference design demonstrates sensorless control of the 3-Phase Switched Reluctance (SR) motor using 56F80x or 56F83XX Digital Signal Controllers. It can also be adapted to 56F81XX Digital Signal Controllers. The concept of this application is that of a sensorless speed closed loop SR drive using flux linkage position estimation. An inner current loop with PI controller is included. The change in phase resistance during motor operation due to its temperature dependency creates errors in the position estimation and significantly affects the performance of the drive. Therefore, a novel algorithm for on-the-fly estimation of the phase resistance is included. The Digital Signal Controller runs the main control algorithm. Rotor position is evaluated using the sensorless flux linkage estimation algorithm. The actual flux linkage is calculated at the rate of the PWM frequency and is compared with the reference flux linkage for a given commutation angle. When the actual flux linkage exceeds the reference, the commutation of the phases is done; the actual phase is turned off and the following phase is turned on. Flux linkage error is used for estimation of the phase resistance at low speeds (US Patent No.: 6,366,865). The actual speed of the motor is determined using the commutation instances. Based on the speed error, the speed controller generates the desired phase current. When the phase is commutated, it is turned on with a duty cycle of 100%. Then, during each PWM cycle, the actual phase current is compared with the desired current. As soon as the actual current exceeds the desired current, the current controller is turned on. The current controller controls the output duty cycle until the phase is turned off (following commutation). Finally, the 3-Phase PWM control signals are generated. The procedure is repeated for each commutation cycle of the motor.
