Title:

A motor controlling device and the De tone state judging method of a stepping motor

Document Type and Number:

Japanese Patent JP5936883

Kind Code:

B2

Abstract:

There is provided a motor control device configured to control an energization state of a coil of each phase for driving a stepping motor having multiple phase coils. The motor control device includes a measuring unit configured to measure a back electromotive voltage induced at a coil of a phase for which energization is stopped, among the multiple phase coils, an acquiring unit configured to acquire temperature information on temperature of the stepping motor or on temperature corresponding to the temperature of the stepping motor, and a detecting unit configured to detect whether the stepping motor is out of step or not based on a result obtained by the measuring unit and the temperature information acquired by the acquiring unit.
