Operating procedure and cooling system mechanism for the motor of an electric powered tool |
摘要 |
An operating procedure for the motor ( 1 ) of an electric powered tool. The operating idle speed of the motor ( 1 ) is set to a value using regulator electronics ( 4 ), and the operating speed is the same as a chosen operating speed (n<SUB>1</SUB>). The motor ( 1 ) runs on a pre-determined and higher idle speed (n<SUB>2</SUB>) for cooling purposes after a specific idle time (DeltaT). while the motor ( 1 ) runs on the pre-determined operating idle speed (n<SUB>1</SUB>). The engine speed is immediately set to the operating speed (n<SUB>1</SUB>) once again, when the motor requires a moment of strain at a certain period of time (T 3 ) to maintain simple and comfortable operating procedures.
