Abstract: Devices and methods to adjust the operation of a washing machine based on system modeling include a motor, a control board, a heater, a number of sensors, and an electronic controller. The controller receives a selected wash cycle program and determines an operating condition of the selected wash cycle program, using data from the sensors. The motor may be used as a sensor. Based on the operating condition, the controller predicts an operational parameter of the washing machine using a system model. The controller may adjust the wash cycle program to keep the operational parameter in bounds or increase efficiency. The operational parameter may be temperature, electrical current consumption, wash efficiency, or energy consumption. The wash cycle program may be adjusted by modifying the duty cycle of the motor or the heater. The system model may be recalibrated upon use to adapt to the particular characteristics of the washing machine.

Abstract: The present application relates to an anticipatory control system and method for electric motor applied to cyclic loads, said system including an electric motor (10), at least an electronic control unit (20), at least an electronic power unit (30), and at least an electric position-monitoring device. The electric motor (10) is electrically driven by the electronic power unit (30), the electronic power unit (30) is electrically controlled by the electronic control unit (20), the system includes an average speed controller and a device for monitoring the position of the electric motor, both implemented by the electronic control unit (20).

Abstract: Reciprocating laundry treating appliances are disclosed. An example laundry treating appliance includes a motor to rotate a drum about the horizontal axis of rotation and an axial drive mechanism to reciprocate the drum relative to the horizontal axis of rotation. The drum may be reciprocated to distribute laundry within the drum. The rotation and reciprocation may be independent and/or simultaneous.

Abstract: A method for controlling and protecting electric motors, specially permanent magnet motors electronically actuated by a control system. The system includes a three-phase inverting bridge, in which the position of the rotor can be monitored by using a position detector physically attached to the axle or through the tension induced in the coils by the magnet, in order to correctly control actuation by the control system. The present invention is also directed to a system for controlling electric motors and an electric motor system. The system includes continuously reading the position detector until a minimum expected time has passed. After the minimum expected time has passed, there is continuous reading of the position detector until a maximum expected time has passed to detect if a position change of the rotor is sensed.

Abstract: A method of producing the core of an electric motor by providing a stack of laminations of magnetic material. Windows are formed in the laminations for one or more magnetic elements to be placed in each window. Each window has an end edge portion (17) which is to be at the peripheral edge (18) of the lamination of the finished version of the rotor. The laminations originally have an annular radial extension (60-61) and after the core is assembled with end caps, the annular radial extension (60-61) is removed so that the window end edge portions (17) are at the periphery (18) of the laminations. There is a polar peripheral portion (20) between each window and the periphery (18) of the lamination and an intermediate peripheral portion (40) between two adjacent polar peripheral portions, with such intermediate polar portions having reduced electrical conductibility and reduced magnetic permeability.

Abstract: A process for magnetizing the permanent magnets of an electric motor rotor and a process for assembling a hermetic compressor motor, whose stator (30) carries a plurality of coils (40), said rotor being operationally positioned with a determined relative angular position in relation to the stator (30) prior to the energization, from an external current source, of a determined number of coils (40) of said stator (30) with a current pulse having a required intensity to generate a magnetic field which produces a homogeneous magnetization transversely oriented in at least one magnetic sector, said current pulse being maintained during a shorter time than that which impairs the coils of said stator (30).
