Document Type and Number:
Japanese Patent JP2015006062
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent a loss of synchronism of a pulse motor when performing initial phase matching, even when a load of the pulse motor is varied or even when the load of the pulse motor is light.SOLUTION: A control method of a pulse motor comprises: a controlling step for setting an excitation current for exciting each phase exciting coil of the motor by a control part; and a driving step for supplying the set excitation current to a drive part.
