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.

This clutch includes an annular clutch housing, a rotationally driven drive-side rotating body, a driven-side rotating body, a rolling body, and a support member. The clutch is configured such that, when the drive-side rotating body starts to rotate when driven, the drive-side rotating body comes into contact with the support member in a rotational direction and presses the rolling body in the rotational direction through the support member, thereby releasing the rolling body from gripping effected by the clutch housing and the driven-side rotating body. The support member includes a load generation section for generating a load which makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts to rotate when driven.

Controlling a door latch of a cooking appliance is provided. A controller monitors motor current of a motor driving a door latch during a locking operation of a door of the cooking appliance. The controller deactivates the motor responsive to the motor current reaching a closed door threshold amount of current. The controller indicates the door being in a closed state responsive to the current draw over time matching a predefined current draw curve.

A generator system having a dynamo that contains an armature, a stator and a housing. The armature rotates about a first axis of rotation. The stator is concentrically positioned around the armature. Both the armature and the stator are free to rotate in opposite directions about the first axis of rotation. The housing of the dynamo is connected to a motor that can rotate the dynamo around a second axis of rotation. There is an angle of inclination between the first axis of rotation and the second axis of rotation. This angle of inclination is selectively altered during operation. By changing the angle of inclination between the two axes of rotation, a precession can be created that adds rotational energy to both the armature and the stator. This increases the output of the dynamo and creates a highly efficient electrical generator.

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.

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.
