  • Laundry appliances using search coils to identify motors and their rotors in order to self-tune control of the motor
    Patent number: 9932701
    Abstract: A laundry appliance is provided, comprising a motor and a controller connected to the motor. The controller determines at least one characteristic of the motor, identifies the motor from a plurality of possible known motors based on the at least one characteristic, identifies the rotor from a plurality of possible known rotors based on the at least one characteristic, and configures at least one motor operation parameter based on the identity of the motor and/or rotor. The at least one characteristic may include the resistance of a stator coil and/or a magnetic flux constant.

  • METHOD FOR THE OPERATING CONTROL OF A CLOTHES WASHING MACHINE AND CLOTHES WASHING MACHINE
    Publication number: 20100293722
    Abstract: The method of the invention encompasses the stages of: rotating the basket in a weighing rotation determined by a microprocessor, of a top-loading machine, already containing the load of clothes to be washed; producing signals for a load sensing device, assembled on a suspension rod of a containment drum that holds the basket, of the maximum and minimum loads to which such suspension rod is subject during each spin of the basket, processing the above-mentioned signals in order to define the average load applied to the suspension rods and with this information, the weight of the load of clothes; and determine, through the microprocessor and as a function of the weight of the load of clothes, the weight of the load of water fed into the containment drum. The method in question also allows control over the various operating functions of the machine, through monitoring the load applied to the above-mentioned suspension rod.
