<P>PROBLEM TO BE SOLVED: To easily control a motor with high accuracy, while taking individual difference of the motor into account. <P>SOLUTION: An exterior unit 4 includes a drive circuit 41 for driving the motor body 10, and a fan 5 is driven to rotate by being fitted to the motor body 10. An interior unit 3 includes a drive circuit 31 for sending and receive a signal between the circuit and the drive circuit 41. The motor 1 includes the motor body 10 and an information-holding portion 11. The information-holding portion 11 holds efficiency information K. The efficiency information K is information regarding inherent motor's efficiency η<SB>M</SB>, based on the individual difference of the motor body 10. The efficiency information K is written onto the drive circuit 31, before the motor 1 is fitted to the exterior unit 4. <P>COPYRIGHT: (C)2007,JPO&INPIT |
