A prestressing structure for rotationally balancing a motor includes a motor stator, a motor rotor, a magnetically conductive member and a balancing magnet. The motor stator has an axial hole and an axial tube extending therethrough. An end of the axial tube provides with the magnetically conductive member. The motor rotor has an inner surface and a shaft seat mounted thereon. A top portion of the shaft seat provides with the balancing magnet which has at least one surface successively attracting at least one surface of the magnetically conductive member for stabilizing rotary movement of the motor.
