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 15):
An apparatus for measuring sensorless brushless DC motor load of a home appliance, comprising:\n a BLDC motor; a flash memory, including a first lookup table; a driving circuit, configured for accelerating the BLDC motor from an initial rotational speed to a first rotational speed; a detecting circuit, configured for detecting phase voltage information corresponding to each phase of the BLDC motor; and a control circuit, configured for obtaining 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, and obtaining a first predicted weight of a load according to the first time period and the first lookup table.
