Abstract

Die erfindungsgemäße Handwerkzeugmaschine hat eine Werkzeugaufnahme zum Aufnehmen eines Werkzeugs. Ein Motor ist mit der Werkzeugaufnahme zum Antreiben der Werkzeugaufnahme gekoppelt. Der Motor ist in einem Gehäuse angeordnet. Das Gehäuse hat eine Halterung, die mit einer mechanischen Verriegelung zum lösbaren Ankoppeln eines Batteriepakets und einem Stromanschluss zum elektrischen Verbinden des Batteriepakets mit dem Motor versehen ist. Eine Kommunikationsschnittstelle dient zum Übermitteln von Eigenschaften des Batteriepakets an eine Motorsteuerung. Die Motorsteuerung beinhaltet einen Sanftanlauf, der eine Drehzahl des Motors von einem Stillstand bis zu einer Solldrehzahl mit einer Rate beschleunigt, wobei die Motorsteuerung die Rate in Abhängigkeit einer von dem Batteriepaket übermittelten Eigenschaft des Batteriepakets steuert.

The hand tool of the invention has a tool holder for receiving a tool. A motor is coupled to the tool holder for driving the tool holder. The motor is arranged in a housing. The housing has a holder which is provided with a mechanical latch for releasably coupling a battery pack and a power connector for electrically connecting the battery pack to the motor. A communication interface is used to transmit properties of the battery pack to a motor controller. The engine controller includes a soft start that accelerates a speed of the engine from a standstill to a desired speed at a rate, the engine controller controlling the rate in response to a characteristic of the battery pack conveyed by the battery pack.
