This report describes the performance test of pony motor system mounted on the MONJU primary prototype pump. The test was conducted under various operation modes, and the following results were obtained: (1)The transition from the main motor to the pony motor was achieved very smoothly. (2)The transmission of the pony motor system worked well with its speed and torque kept constant. (3)start-up of a pump with a pony motor was accomplished very smoothly. (4)Apony motor current was about 6365% of it rated operation. (5)A characteristics of pony motor system in high temperature atomosphere remained as same as that in the room temperature. (6)The amplitude of pony motor bearing vibration during operation was a little.
