Abstract: <P>PROBLEM TO BE SOLVED: To prevent a drive circuit from being broken by an induced voltage occurring at a motor, in a motor drive system comprising a motor and its drive circuit.  <P>SOLUTION: The upper limit of the number of rotation of a motor is set based on the breakdown strength of a drive circuit, and the rotation of the motor is controlled not to exceed the upper limit. In general, the loadless induced voltage of a motor has a temperature characteristics, and the breakdown strength of the element of a drive circuit has a temperature characteristics as well. So, the upper limit of the number of rotation is set by considering the temperature characteristics. For example, a normal maximum number of rotation N<SB>0</SB>is not allowed but an upper limit number of rotation N<SB>1</SB>is set at a temperature t<SB>1</SB>or below where a loadless induced voltage (62) of a motor exceeds a breakdown strength (60) of an element, and control is performed not to exceed it.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
