LINEAR STEP MOTOR (VERSIONS) Russian patent published in 2013 - IPC H02K41/03 

FIELD: electricity.

SUBSTANCE: in a linear step motor (LSM) an element moving a movable part is a system of driving elements - levers of forward and reverse travel driven by electromagnets connected to a control system installed in a body. On the inner part of the body there are sliding bearings. There are sensors to monitor the position of the movable part of the motor connected to the control system. According to the first version there are return springs arranged coaxially with levers. On the movable part there are hooks. According to the second version, the control system is installed in the body, levers and control systems are arranged on the movable part, and hooks - accordingly on the body. Levers are arranged with a pull-in core. The difference of the third version from the second one consists in the fact that levers have a hinged mechanism, are arranged inside the body in one transverse plane and are arranged in the form of sectors. Movement of the movable part happens along rollers. The body is movable, and the movable part is fixed on the stationary mechanism.

EFFECT: expansion of functional and technological capabilities of a linear step motor and its simplified design due to application of levers as a driving element.
