Abstract
PURPOSE: To perform conveyor maintenance quickly and positively by measuring the motor load rate easily and accurately by the use of the primary current of a conveyor driving motor.
CONSTITUTION: An instrumental transformer 22 which induces the primary current of a motor 10 for having the same represent the load rate of the motor is connected to a converter 24 converting alternating current into direct one. The converter 24 is connected to an operator 28 through an integral circuit 26 which suppresses rapid load variations of the motor 10. The operator 28 is connected to a function converter 30 which converts the curved relationship between the voltage and the load into a linear one. The function converter 30 is connected to a load rate indicating circuit 32.
