Title:
CURRENT MEASURING APPARATUS
Document Type and Number:
Japanese Patent JP2008215949
Kind Code:
A
Abstract:
To provide a compact and low-cost current measuring apparatus used for a motor.
The current measuring apparatus 4 for measuring current flowing in the motor 1 is equipped with: a diode D1 being connected in series with the motor 1 on the low-potential side of the motor 1 in a circuit including the motor 1 and a battery 3 for supplying a power to the motor 1, and connected in a forward direction in which the current flows from the battery 3 to the motor 1; and a current calculating means 6 which is connected in parallel with the diode D1, measures a voltage applied to the diode D1 and calculates the current flowing in the motor 1 based on a measured voltage.
