An electric motor and an elevator system. The electric motor includes: a casing; a stator supported by the casing, the stator including a stator yoke and stator teeth, and a winding being wound around the stator teeth and generating a magnetic field when energized; and a rotor which rotates under the action of the magnetic field; wherein at least a portion of the stator yoke is formed as a moving plate which is movable between a first position and a second position; and when the winding is energized, the moving plate is capable of moving from the first position to the second position under the action of the magnetic field, and in the second position, the moving plate is separated from the rotor; and after the winding is de-energized, the moving plate is moved from the second position to the first position under the action of a spring force.
