摘要： A voltage mode control method and apparatus for extending speed range operation from a sinusoidally excited permanent magnet motor is described. The method includes a determination of a maximum value from a first set of parameters with each parameter having a known maximum value as well as a reading of a second set of parameters. A computation of a first derived angle using the first set of parameters and the second set of parameters is then performed. A computation of amplitude of phase voltage and a second derived angle using the first derived angle follows. A resultant output comprising a set of derived command voltages for controlling a power circuit is created whereby the power circuit can achieve required torque levels with lower currents for power switches.

摘要： An exemplary embodiment of the invention is a method for torque control of a PM synchronous machine. The method includes obtaining a torque command signal and a machine speed and determining an operating mode in response to the torque command signal and the machine speed. The operating mode includes a first operating mode and a second operating mode. In the first operating mode, a stator phase voltage magnitude is computed and an angle between the stator phase voltage and a stator phase back emf is determined in response to the stator phase voltage magnitude. In the second operating mode, the stator phase voltage is set to a predetermined magnitude and the angle between the stator phase voltage and the stator phase back emf is determined in response to the predetermined magnitude.

摘要： A rotary position sensor featuring a magnetized rotor which produces a magnetic flux density that varies sinusoidally with respect to the angular position of the rotor, which may be either a selectively magnetized ring or disk. The magnetic flux density produced by the rotor is measured by a sensor that responds in a linear fashion to the magnitude of the radial component of the magnetic flux density. Typical embodiments would use magnetic flux density sensors, as for example either linear Hall sensors or magnetoresistive type sensors. The measured magnetic flux densities are then used as in a traditional resolver to compute position or used to directly generate control signals to operate, for example, a motor.

摘要： A magnetic sensor provides an output voltage range having first and second linear slopes. Proper selection of magnetic sensor dimensions enables changes in magnetic flux density upon the passage of at least one tooth and one slot of a target wheel past the magnetic sensor to be represented as a linear magnetic sensor output comprised of at least one linear range whereby linear interpolation of position is possible with appropriate signal processing algorithms.

摘要： A method for assembling a permanent magnet ring on a rotor body for an electric motor or generator where the body has a higher coefficient of expansion than the permanent magnet ring includes the steps of sizing the internal diameter of the ring for the greatest thermal expansion of the rotor and introducing longitudinal grooves in the rotor surface uniformly spaced about its circumference to accommodate the expansion of the adhesive used to bond the ring to the rotor.

摘要： A rotary actuator for a vehicle having an electric/hydraulic motor that is used to rotate a strut tube. The motor is mounted inside the suspension spring and around the tubular portion of the strut tube. A first shaft receives the output of the motor and transfers it to a gearbox that reduces the speed. A second shaft receives the output of the gearbox. A torque rod is attached to the opposite end of the second shaft and transfers the rotation of the second shaft through a semi-circular slot in the spring seat to a annular member. The annular member is further attached back to the strut tube, thus when the motor is energized, the rotation is transferred through the assembly to the strut tube causing it to rotate and steer the road wheel to which it is attached.

摘要： A combination starter-generator system for use in a vehicle is provided. The vehicle has an internal combustion engine and a battery. The system includes a starter-generator electrically coupled to the battery to generate a current and to start the internal combustion engine. A drive mechanism connects the starter-generator machine and the internal combustion engine. The starter-generator machine generates the current by receiving a charging torque from one side of the drive mechanism and starts the internal combustion engine by imparting a starting torque to a different side of the drive mechanism. The charging torque or the starting torque is a greater torque. A passive tensioning system cooperates with the drive mechanism to tension the drive mechanism only at the side of the greater torque.
