Abstract:
A method for measuring sensorless brushless-DC motor load, adapted to a home appliance, including: accelerating, through the use of a driving circuit, a BLDC motor from an initial rotational speed to a first rotational speed; disabling, through the use of a control circuit, the driving circuit; obtaining, through the use of a detecting circuit, phase voltage information corresponding to each phase of the BLDC motor when the BLDC motor is decelerated from the first rotational speed to a second rotational speed; obtaining, through the use of the control circuit, a first time period during which the BLDC motor decelerates from the first rotational speed to the second rotational speed according to at least one piece of the phase voltage information; obtaining, through the use of the control circuit, a first predicted weight of a load according to the first time period and a first lookup table.

Claim (Index 16):
The apparatus as claimed in  claim 15 , wherein:\n the flash memory further comprises a second lookup table; the driving circuit is further configured for accelerating the BLDC motor at a predetermined torque from the initial rotational speed to a third rotational speed, the control circuit is further configured for measuring an acceleration time period during which the BLDC motor accelerates from the initial rotational speed to the third rotational speed and obtains a second predicted weight of the load according to the acceleration time period and the second lookup table; and the control circuit is further configured for calculating counter-electromotive force information corresponding to the BLDC motor according to the phase voltage information, obtaining the rotational speed information of the BLDC motor according to the counter-electromotive force information, and obtaining the first time period according to the rotational speed information.
