Abstract
Disclosed is a core including a plurality of core layers in a laminated structure formed through one-directional press shearing and having an insulating layer formed on the surface thereof prevented from being damaged by burrs formed through the press shearing when a winding coil is wound on and around the core, and a motor having the core. The core for a motor includes: a plurality of core plates having a laminated structure formed through one-directional press shearing; and a chamfered portion formed on at least some of the corners of a face opposed to one face of the core plate to which force is applied by the press shearing.

A core for a motor, the core comprising:
- a plurality of core plates having a laminated structure formed through one-directional press shearing;
- and
- a chamfered portion formed on at least some of the corners of a face opposed to one face of the core plate to which force is applied by the press shearing,
- wherein the chamfered portion is formed on each of the plurality of core plates.
A motor comprising:
- a core including a plurality of core plates having a laminated structure formed through one-directional press shearing and a chamfered portion formed on at least some of the corners of a face opposed to one face of the core plate to which force is applied by the press shearing, and having a winding coil wound thereon;
- and
- a rotor including a magnet interacting with the coil to generate an electromagnetic force and rotating a shaft,
