Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The rotary induction motor of claim 1 , further comprising: a stator bearing connected to the housing and configured to rotate a rotation axis of the stator. 3. The rotary induction motor of claim 1 , further comprising: a rotation sensor adhered to an internal side of the housing and configured to sense rotation amount of the rotator. 4. A rotary brushless direct current electric (BLDC) motor having a hall sensor, the rotary BLDC 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, and 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. 5. A rotary alternating current (AC) servo motor having a hall sensor, the rotary BLDC 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, and 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 is formed by 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.
