摘要： A control circuit is applied to a system provided with a rotary electric machine, a power converter electrically connected to a winding of the rotary electric machine, a power source, a cutoff switch provided on an electrical path that connects the power source and the power converter, and a storage unit. The control circuit is provided with a failure determination unit that determines whether a failure occurs in the system and a regeneration prevention unit that prevents a power regeneration, where a current flows from a rotary electric machine side towards a storage unit side, from occurring. In the case where the failure determination unit determines that a failure occurs in the system, the cutoff switch is turned OFF after the regeneration prevention unit prevents an occurrence of the power regeneration.

摘要： An electric machine includes a stator and a rotor energizable by magnetic fields produced by the stator when receiving a stator current to produce relative motion between the rotor and the stator. A controller is configured to send the stator current through the stator at a current angle measured from the closest one of a pole of the rotor, determine a desired operational output of the electric machine, and determine a desired rotor motion corresponding to the desired operational output of the electric machine. The controller is further configured to calculate a vector control modulation applied to the stator that elicits the desired rotor motion, and adjust the current angle of the stator current based on the vector control modulation to cause the rotor to perform the desired rotor motion and achieve the desired operational output of the electric machine.

摘要： An induction machine with integrated magnetic gears is disclosed. The machine comprises two rotors and two stators. An outer stator has ferromagnetic material, producing a rotating magnetic field with a defined number of pole pairs synchronized with a supply frequency. A high speed rotor has ferromagnetic material and a combination of rotor bars and permanent magnet pole pieces selected so that the permanent magnet pole pieces do not interact with the outer stator magnetic field. The high speed rotor rotation is asynchronously coupled to the outer stator magnetic field. An inner stator has ferromagnetic steel segments that modulate the field produced by the high speed rotor permanent magnets. A low speed inner rotor has ferromagnetic material and permanent magnet pole pieces, the low speed inner rotor counter-rotating to the high speed rotor. The low speed inner rotor is synchronously coupled to the high speed rotor using modulation harmonics.

摘要： Technical solutions are described for a motor control system, such as one used in a steering system, the motor control system including multiple controllers. In an example, the motor control system includes a first arbitration module associated with a first controller, and a second arbitration module associated with a second controller. The first arbitration module generates a first arbitrated input signal based on a first input signal directed to the first controller, and a second input signal directed to the second controller. The second arbitration module generates a second arbitrated input signal based on the first input signal and the second input signal. The first controller generates a first control output using the first arbitrated input signal, and the second controller generates a second control output using the second arbitrated input signal.

摘要： It is an object of the present invention to provide a technology capable of reliably suppressing a surge voltage even in a case where noise having a small pulse width is generated. A drive protection circuit that drives and protects a switching element includes a gate driving circuit that drives the switching element in response to a gate driving signal and an overcurrent protection circuit that operates a soft cutoff circuit upon an overcurrent of the switching element, the soft cutoff circuit causing the switching element to transition from ON to OFF at a switching speed slower than that of the gate driving circuit. In the drive protection circuit, in a case where a pulse width of ON of the gate driving signal is less than or equal to a response time of the overcurrent protection circuit, the drive protection circuit operates the soft cutoff circuit to cause the switching element to transition from ON to OFF, regardless of the overcurrent.

摘要： A motor controlling apparatus includes a first target torque value calculator, a frequency detector, a second target torque value calculator, a torque command value calculator, a torque limiter, and a controller. The first target torque value calculator calculates a first target torque value, which is a target value of an output torque of a motor. The frequency detector detects a motor rotational frequency. The second target torque value calculator calculates a second target torque value based on the rotational frequency. The torque command value calculator mathematically combines (e.g., adds) the first and target torque values to calculate a torque command value. The torque limiter sets the signs of the first target torque value and the torque command value to be equal to limit the torque command value according to the first target torque value. The controller controls the motor based on the limited torque command value.
