Title:
MONITOR FOR PLURALITY OF MOTORS
Document Type and Number:
Japanese Patent JPS60190196
Kind Code:
A
Abstract:
PURPOSE:To automatically correct an average vector upon varying of the number of operating motors by combining in parallel the outputs of individual vector detectors through resistors and switches to obtain the average vector, and cooperating the switch with switches for separating the motors from the power source. CONSTITUTION:The vectors of the individual currents flowed to motors 5-1-5-n are combined in parallel through resistors 9-1-9-n to obtain an average vector of the currents flowed to the many motors. Since the combination of the individual vectors of the motors during stopping is separated by switches 8-1a- 8-na cooperated with motor switches 8-1-8-n, the correction of the average vector upon varying of the number of motors can be automatically performed.
