Abstract
An apparatus and a method of controlling a motor are provided for reducing vibration of an electric vehicle that maximize regenerative energy by limiting a vibration reduction torque at a maximum regenerative braking torque region of a motor. The method includes comparing a battery state of charge (SOC) with a predetermined SOC when a regenerative braking of the electric vehicle is required and calculating a size of vibration component of the electric vehicle when the battery SOC is less than the predetermined SOC. Further, the size of vibration component is compared with a first predetermined value and a vibration reduction torque of a driving direction is limited when the size of vibration component is less than the first predetermined value.
