Abstract
A method for determining an updated rotor speed for a motor is provided. The method obtains, by a processor, a current rotor speed of the motor; determines a current mode for the motor, based on the current rotor speed, wherein the current mode comprises a low-speed mode, an intermediate speed mode, or a high-speed mode; detects one or more Hall events associated with a plurality of digital Hall Effect sensors coupled to the motor, based on the current mode; calculates, by the processor, a new rotor speed for the motor, based on the one or more Hall events and the current mode; and transmits the new rotor speed as a motor speed feedback signal, for digital speed control of the motor.
