Abstract:
1. A method of operation of a laundry treating appliance having a rotatable drum at least partially defining a treating chamber in which a laundry load is received for treatment, and a motor rotatably driving the drum in response to a control signal, the method comprising: rotating the drum with the motor according to a speed profile having at least a constant speed phase, where the drum is rotated at a constant speed, and an acceleration phase, where the drum is accelerated to the constant speed; monitoring power provided to the motor during the acceleration phase; calculating power to be provided to the motor for the constant speed based on the monitored power during the acceleration phase; determining the power provided to the motor during the constant speed phase; and determining an inertia of the laundry load based on a difference between the calculated power and the determined power.
