Title: Controller for motor
Inventor: HATTORI MAKOTO
IPC: G01R1/20
Filed: 2002-05-16
Abstract: <P>PROBLEM TO BE SOLVED: To detect a high current by a small and low-cost current sensor.  <P>SOLUTION: A controller for a motor comprises an input part 2 connected to a power supply, and an output part connected to the motor. The current sensor 4 is attached to the input part 2. A bypass part 3 is connected in parallel with the input part 2, and the current sensor 4 is attached to the bypass part 3. Since the bypass part 3 is installed in parallel with the input part 2, a current flowing in the bypass part 3 is smaller than a current (a total current supplied to the motor) to be input to the input part 2. Consequently, even the small and low-cost current sensor sufficiently detects the current flowing in the bypass part 3.  <P>COPYRIGHT: (C)2004,JPO
