Motor controlling method involves driving tool of battery driven machine tools, and continuous monitoring of motor current and battery voltage takes place and continuous comparison of battery voltage takes place with threshold value

摘要

The method involves driving a tool (12) of a battery driven machine tools (10) in an on-position of motor switch (21). An electronic device (22) initialises a control device (20) and a motor (11) is switched-on. A continuous monitoring of a motor current and a battery voltage takes place. A continuous comparison of the battery voltage takes place with a threshold value, which is stored in a memory of the electronic device. An independent claim is also included for a machine-tool with a control device which has an electronic unit.
