Electric motor suffers from the increased demand will always be accompanied by a reduction in its speed
When the electric motor suffers from the increased demand will always be accompanied by a reduction in speed. Overloading the electric motor makes it raised the largest amount of electric current and this will cause the temperature of the windings at a very dangerous level.
If this situation persists in the electric motor, the electric insulating material of the electric motor is broken and thus short-circuits will be developed. When the electric motor suffers from the overhead is high, the electric motor insulation can burn and the windings and the core may also suffer severe damage.
The resistive temperature sensors are in electric motor to detect excess heating. The PLC in turn, there resistive temperature sensors and, if required, the electric motor is turned off based on RTD readings. https://www.mrosupply.com/hydraulics-and-pneumatics/hose-reels/2516620_sh-n-350_coxreels/
