The present invention may provide a motor including a stator, a shaft having a hollow and disposed inside the stator, and a magnet disposed on an outer circumferential surface of the shaft, wherein the shaft includes protrusions in contact with the magnet, and the protrusions include first faces protruding from the outer circumferential surface of the shaft and second faces concavely disposed in an inner circumferential surface of the shaft.

Motor

The present invention may provide a motor including a housing, a stator disposed in the housing, a rotor disposed inside the stator, and a shaft coupled to the rotor, wherein the stator includes a stator core, a first insulator disposed on the stator core, and a coil disposed on the first insulator, the first insulator includes a body on which the coil is disposed, a guide extending from one side of the body and including an opening, and a holder extending from one portion of the guide and including a groove, and one portion of the coil is disposed in the opening of the guide and the groove of the holder.

Motor having stator with guide and holder

The present disclosure provides a motor router comprising: an annular body having a first coil guide; and a guide part formed to protrude from the body, and having a second coil guide to which the first coil guide is connected, and thus the present invention reduces the number of parts and has a simplified configuration, thereby providing an advantageous effect of reducing manufacturing processes and manufacturing costs.

Provided is a commutator of a motor including a body and hooks forming coil-receiving spaces between the body and inner surfaces of the hooks, wherein the hooks include recesses concavely formed on the inner surfaces of the hooks, and coils are seated on the recesses. Thus the present disclosure provides an advantageous effect of increasing fixing force of the hooks.

Commutator of motor having hooks and a plurality of recesses and motor having the same

A motor is provided, the motor including an insulator body coupled to a stator core wound with a plurality of coils applied with an electric power having mutually different polarities to prevent the coils and the stator core from being short-circuited, a terminal housing coupling unit integrally constituted with the insulator body, protruded to a circumferential direction and coupled to a terminal housing supplying an external electric power, a terminal housing coupled to the terminal housing coupling unit to supply an electric power to the motor, a fixing unit position-fixing the terminal housing to the terminal housing coupling unit, and a regulation unit mounted on the fixing unit to regulate a rotation angle of the terminal housing.
