Title:
HIGHLY ACCURATE DETECTOR FOR MOTOR CURRENT
Document Type and Number:
Japanese Patent JP2018132341
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a current detector which reduces a resistance value added exclusively for detecting a current and has a high precision.SOLUTION: The current detector includes a motor 1, a motor driving circuit 2, and conduction path means for attaining conduction to the motor, and calculates a current value by detecting the voltage of a current flowing in the motor 1 by a current detection resistor 4 and operating the current by a detection circuit. The current detection resistor 4 has the conduction path means for attaining conduction to the motor.SELECTED DRAWING: Figure 3
