Abstract: Systems, methods, and apparatus, consistent with principles of the present invention, allow an unmodified device, for example, dc starter motor (230), that normally operates at a first voltage (108) to function in an electrical system providing a second voltage (109), which is different from the first voltage, and received from the power source (105). A device actuator (135), such as a solenoid, is controlled using the second voltage (109). The first voltage (109) is produced and supplied to the device (130) in response to a first action of the actuator, for example, to the device (130) in response to a second action of the actuator (135), for example, upon solenoid retraction after engine cranking.

Abstract: A system for controlling the torque of a sinusoidally excited permanent magnet motor (12). The system includes a rotor position encoder (14), speed measuring circuit (16), controller (18), power circuit (20) and power source (22). The position and speed signals (24, 26) and a torque command signal (28) are applied to the controller (18). The torque command signal (28) is indicative of the desired motor torque. The controller (18) determines a voltage amplitude (30) required to develop the desired torque by using the position, speed, and torque command signals (24, 26, 28) and other fixed motor parameter values. The controller (18) transforms the voltage amplitude signal (30) into three phase signals by determining phase voltage command signals (Va, V

Abstract: A controllable switching mechanism (100) integrally housed within a motor (100) to optimally couple the windings (112, 114, 116) of an AC motor for improved torque-speed characteristics. The switching mechanism (100) includes a plurality of double throw switches (121, 123, 125) each with a first and second closed position. The first closed position results in connecting the windings (112, 114, 116) of the AC motor (102) in one configuration for improved torque at lower rotor speeds. The second closed position results in connecting the windings (112, 114, 116) of the AC motor (102) in another configuration for improved torque at higher speeds. The winding configurations may be wye for lower speeds and delta for higher speeds. An accompanying controller (104), based on various inputs, optimally senses the best time for switching between configurations and sends appropriate control signals to the switching mechanism (100) housed with the AC motor (102).

Abstract: A motor control system for a two-phase brushless DC motor (11; 111) uses measured EMF voltage (17; 117) from the passive set of stator coils (113, 114) to control commutation (19; 119) . A microcontroller (101) receives the EMF voltage measurement (16; 103) and compares it to a threshold voltage value, which may be speed-dependent for advance commutation at high motor speeds. A match of the EMF voltage measurement with the threshold value triggers commutation of the drive to the opposite set of stator coils. The microcontroller also has an up-down counter timer (105) whose count value is compared to an external speed reference (13; 109) . Each match of the count value triggers a transition in a pulse-width modulated (PWM) drive signal. The duty cycle of the PWM signal establishes an average drive voltage that controls motor speed.

Abstract: A digitally adaptive controller circuit (100) for commutating a brushless, sensorless, DC motor (110) in either of two directions adapted to receive digital back electromotive force (BEMF) detector (130) signals. The digital circuit is driven by an input clock that is adjustable to configure the motor controller for use with a broad range of DC motors. The circuit includes commutational logic that decodes a current commutational state and a user-definable binary direction input into logic levels for digital control signals for controlling motor drive switches. The circuit also includes a signature analyzer to compare logic levels in the BEMF detector (130) signals with expected logic levels based on an expected rotor position and direction of rotation. The digital circuit commutates the motor (110) if the logic levels in the BEMF detector (130) signals are at the expected logic levels. The digital circuit is compact and simple enough to be deployed onto a single programmable logic device.
