Abstract:
A motor control apparatus that controls a stepping motor includes a calculation unit configured to determine a time with respect to a distance based on a theoretical formula expressing a parameter in an acceleration period or deceleration period of the stepping motor. The calculation unit includes a first calculation unit and a second calculation unit. The first calculation unit is configured to apply an iterative root-finding procedure to a distance which is a function of a time included in the theoretical formula to determine the time with respect to the distance of the n-th step expressed using a reciprocal of a derivative of the function. The second calculation unit is configured to apply the iterative root-finding procedure to the reciprocal of the derivative to determine the reciprocal of the derivative at a time when the first calculation unit determines the time with respect to the distance of the n-th step.

Claim (Index 11):
The motor control method according to  claim 10 , wherein, in the calculating, the step time is calculated as a difference between the time with respect to the distance of the n-th step and a time with respect to a distance of (n\u22121)th step.
