DEVICE FOR MONITORING THE ENDURANCE OF AN ELECTRICDEVICE FOR MONITORING THE ENDURANCE OF AN ELECTRIC MOTOR MOTOR

摘要

The proposed device for monitoring the endurance of an electric motor contains a current transducer, an analog-to-digital converter, two pulse counters, timing interval distributor, two AND logic elements, a frequency divider, a pulse generator, a digital comparator, a date register, two adders, a temperature transducer, and an endurance set-point unit. The output of the pulse generator is connected to then input of the frequency divider. The output of the register is connected to the input of the first adder. The device contains additionally a functional converter, four OR logic elements, the device reset circuit, a voltage converter, a unit for setting the motor speed, a unit for setting temperature rate, a differential amplifier, the second analog-to-digital converter, the second timing interval distributor, the second pulse generator, a binary counter for measuring the motor endurance, an OR-NOT logic element, and an amplifier.
