<P>PROBLEM TO BE SOLVED: To provide a motor driving apparatus capable of highly accurately detecting the wobbling of a motor even when variation occurs in motor production. <P>SOLUTION: The motor driving apparatus includes a driving motor 1 for generating a rotation driving force; a container 12 provided on the driving motor 1 and rotating on the basis of rotation driving force of the driving motor 1; a magnetic pole detecting portion 2 for detecting the magnetic pole of the driving motor 1; a specific position detecting portion for detecting the specific position of the magnetic pole of the driving motor 1; a RAM 8 for storing an inter-magnetic pole distance time obtained based on the output of the magnetic pole detecting portion 2 and used as a time required for rotation for the inter-magnetic pole distance of the driving motor 1; and a ROM 9 for storing an inter-magnetic pole distance correcting time for correcting the inter-magnetic distance time. The wobbling of the driving motor 1 to be generated due to deviation of contents put into the container 12 is detected using the inter-magnetic pole distance time and the inter-magnetic pole distance correcting time. <P>COPYRIGHT: (C)2008,JPO&INPIT |
