Abstract

Provided is a stator of a motor. The stator of the motor includes engaged portions in which two adjacent unit yokes are engaged with each other in a folding-type stator core, and each of the engaged portions may include a contact surface in contact with engaged portions of two adjacent unit yokes, and at least one non-contact surface arranged at a height smaller than a height of the contact surface in a circumferential direction not to be in contact with the engaged portion of another unit yoke adjacent in the circumferential direction. Thus, since the at least one non-contact surface is arranged in each of the engaged portions in which two adjacent unit yokes among unit yokes of the stator core configured as a folding-type core are engaged with each other, internal stress that may occur when the two adjacent engaged portions come into close contact with each other while the two adjacent unit yokes are being folded may be attenuated and iron loss caused by the internal stress in the two adjacent unit yokes may be suppressed, thereby improving motor efficiency and motor performance.
