摘要: A method of determining an airflow parameter in a vacuum cleaner comprising a motor-fan assembly comprises receiving one or more signals relating to one or more operational parameters of the motor. The method further comprises determining a torque of a rotatable shaft of the motor based on the one or more operational parameters. The method also comprises determining an airflow parameter based on the determined torque of the rotatable shaft of the motor.

摘要: A power tool comprising: a motor; a fastener gripping portion operatively coupled to the motor for causing movement of the fastener gripping portion between a home position and a retracted position to set a fastener; a home position sensor for generating output indicative that the fastener gripping portion has reached the home position during a reset stage of operation in which the fastener gripping portion is moved towards the home position; and a controller for receiving motor turn information indicative of the number of turns of the motor and for monitoring the position of the fastener gripping portion based on the motor turn information and the output generated by the home position sensor.
