This patent describes a three-phased reluctance motor () of stepper type with six coils placed in six slots (-) in a stator (), n*6 teeth () in rotor () where n is an integer equal to or larger than 3, typically 8-16 and were the teeth () in stator () are shifted unsymmetrical so the motor () can produce torque at every angle between rotor () and stator ().

Three phased balanced or unbalanced asymmetric reluctance motor

A self lock mechanism for rotating actuators, which allow rotation from one side while deny rotation from the other side, comprising sets of rollers arranged between a housing and a valve connection part, configured with a special shape to cause locking if the mechanism is attempted twisted from the valve side, a motor connection part to press rollers out of locking position and release the locking before the motor connection part makes contact with the valve connection part and start transferring torque. The rollers may be separated and kept in place by a wing on the valve connection part or by springs.
