We use modern electronic means nowadays to protect power tools from overload damage through improper use. Sensors supervise the motor power consumption and turn off the power tool if it is permanently overloaded. This can also happen in reaction to the motor temperature. Temperature sensors have the same function; they initiate the cutout process if a critical temperature, for example in the exitor winding, is exceeded. Often this critical condition is signalled to the user by a warning light (display) either just before or after the circuit is broken.
