Speed control. Following the commutation sequence in a given order helps in ensuring the proper rotation of the motor. Motor speed, then, depends upon the amplitude of the applied voltage. The ...
Small, high-speed BLDC motors usually have very low inductance compared to a conventional BLDC motor. In this case, the bipolar PWM cannot be used. A solution can be achieved with higher frequency, ...
Precise setting of a speed profile can be programmed into the built-in non-volatile memory (NVM). Operating from a supply voltage ranging from 5.5 to 27V, the device includes selectable closed loop or ...
