METHOD AND CIRCUIT FOR ANALYZING INDUCED VOLTAGE OF EXCITINGCOIL FOR STEP MOTOR

Document Type and Number:

Japanese Patent JPS5947998

Kind Code:

A

Abstract:

A method is described for analysing the voltage induced in an exciter coil (1) of a stepping motor. After energization the exciter coil (1) is loaded by a low impedance (5) so that the induction voltage can produce a current. Subsequently, it is attempted to maintain the current through said coil equal to zero by periodically connecting said coil to a positive or negative voltage (4). The pattern of consecutive polarities of these periodic energizations is analysed.
