A drive system thermal temperature rise test and compensation system. The system has an optical non-contact type sensing head mounted on a main shaft of a machine tool, and a sensing center is formed in the center of the sensing head. A platform driven by a transmission device of the machine tool is provided with plural ball lens devices, and a temperature sensor for transmitting temperature data externally is further provided on the transmission device. After the machine tool sequentially records an original point coordinate for each ball lens center by using the sensing head, the sensing head is cyclically and sequentially moved to the original point coordinate of each ball lens, so as to measure a displacement error between the sensing center and the ball lens center resulted from thermal shifts of the transmission device, as well as capable of measuring multiaxial errors and using various axial temperatures for compensation.
