Disclosed is a motor control system of an eco-friendly vehicle and a method thereof. The motor control system of the eco-friendly vehicle according to an embodiment of the present invention comprises: a motor which rotates a driving shaft by rotational force generated by using electricity to drive the eco-friendly vehicle; a bearing which supports the driving shaft in a motor housing and includes magnetic lubricant injected in a closed space inside a bearing housing in which a plurality of bearing balls are disposed; a controller which varies degree of lubrication of the magnetic lubricant through current control based on a motor rotational speed or a vehicle speed. The motor control system varies the degree of lubrication based on the motor rotational speed or the vehicle speed to improve durability.
