    摘要: A device and method for matching the rates of speed at which an electric motor that is drivingly connected to a worm gear raises and lowers a window in an automobile power window assembly. By axially displacing the motor's armature, and/or by varying the thread and tooth profiles of the worm and the gear, the amount of torque produced by the motor and transmitted through the worm gear can be altered. In order to compensate for the effect of gravity on the motor load and on the window's speed of ascent and descent, more torque is provided when the window is being raised and less torque is provided when the window is being lowered.

    摘要: A control system for a brushless DC motor, preferably used in a power steering system in a vehicle. Presently delivered torque is computed without measuring currents in the motor. A demanded torque signal is received, and a torque error signal is produced. The torque error signal is modified by an inertial torque component, if the motor is accelerating. In response to the modified error signal, the control system first attempts to increase motor torque by increasing motor voltage, if that is possible, without increasing magnetic field which is parallel with the magnetic field of the rotor. If that is not possible, then motor voltage is held fixed, and the magnetic field just mentioned is increased.

    摘要: A powered apparatus includes a driven component that is movable along a path and a drive motor that moves the driven component along the path. A motor speed detector monitors an instantaneous speed of the drive motor at each position along the path. An electronic control unit operates the drive motor and includes load profile data representing a number of motor loads associated with respective positions of the driven component along the path. A calculating component determines a calculated final rest position of the driven component by adding a current position of the driven component along the path and an adjustment coefficient representing an additional distance of travel along the path based on the instantaneous speed of the drive motor and a respective motor load associated with the additional distance of travel. A non-volatile memory component stores the calculated final rest position of the driven component.

    摘要: A control system for an electric motor used to provide mechanical power to a power steering system in a vehicle. The motor is of the two-phase type with an independent winding for each phase, or of the three-phase type with two independent stator windings. Two inverters are provided, one for each winding. Each inverter provides AC current to run the motor. If a fault is detected in an inverter or its stator winding, current is terminated to that inverter, and the motor is run using the other winding. In addition, if the vehicle battery is installed with incorrect polarity, components within the inverters can be destroyed. The invention detects the incorrect polarity, and blocks current to the inverters.

    摘要: An apparatus and method for controlling sinusoidal currents in inductive loads during zero-crossing to reduce distortion. The apparatus and method utilizes first and second PWM signals during a single PWM cycle to apply opposite voltage signals to obtain a net desired voltage across the inductive load. The voltage applied to the load is compared with a threshold and, when the applied voltage is greater than the threshold, normal PWM signals are applied to the load, and when the applied voltage is less than the threshold, an adjusted voltage formed of first and second PWM signals is applied to the load.

    摘要: A control system for an electric motor. Field Oriented Control, FOC, uses a digital control system, and attempts to maintain the rotating stator magnetic field ninety degrees ahead of the rotor field, in order to maximize torque. However, if a three-phase motor is used, which is very common, large amounts of computation are required, to convert from a three-phase coordinate system to an orthogonal coordinate system. The invention replaces the three-phase motor with a two-phase motor, which has been found to impose certain additional costs, but also provides benefits.
