Abstract
An embodiment relates to a power terminal and a motor including the same, the power terminal comprising: a body; a pin portion extending upward from the body; a coupling portion formed at one end of the body and coupled to an end of a coil; a first protrusion protruding downward from the body; and a second protrusion protruding downward from the body, wherein the second protrusion is arranged to be spaced inward or outward form the body. As a result, the power terminal can improve the productivity through process simplification while satisfying a true position geometric tolerance.
