Abstract
An operating procedure for the motor () of an electric powered tool. The operating idle speed of the motor () is set to a value using regulator electronics (), and the operating speed is the same as a chosen operating speed (n). The motor () runs on a pre-determined and higher idle speed (n) for cooling purposes after a specific idle time (ΔT). while the motor () runs on the pre-determined operating idle speed (n). The engine speed is immediately set to the operating speed (n) once again, when the motor requires a moment of strain at a certain period of time (T) to maintain simple and comfortable operating procedures.
