Abstract
A rotary motor capable of reducing repulsive force is disclosed. The rotary motor comprises a housing, a stator located in the housing and configured to have a shape of a cylinder on which a central part is penetrated, and a rotator configured to rotate in the stator. Here, the stator rotates clockwise or counterclockwise.
Claims5
A rotary induction motor comprising:
- a housing;
- a stator located in the housing and having a shape of a cylinder on which a central part is penetrated;
- a rotator located in the central part of the stator and configured to rotate based on a direction of an axis of the cylinder;
- a base configured to support the housing;
- and
- at least one displacement limitation member configured to connect the housing to the base, wherein the at least one displacement limitation member reduces vibrations transmitted to the base,
- wherein the stator is configured to rotate in a direction opposed to a rotation direction of the rotator based on the direction of the axis of the cylinder,
- wherein the at least one displacement limitation member includes a torsion spring and a damper, and
- wherein the at least one displacement limitation member dissipates a repulsive torque generated by the rotation of the rotor, and only a torque of the at least one displacement limitation member smaller than the repulsive torque is transmitted to the base.
