MANUALLY OPERATED WORK DEVICE HAVING A CONTROL CIRCUIT FOR AN ELECTRIC MOTOR THAT DRIVES OSCILLATING TOOLS

The tool (1) has a control device provided in a drive circuit for operation of an electromotor (M) two rotation directions. The control device independently determines a selected rotation direction of the electromotor for a next operating cycle depending on a control variable. The electromotor is st...

Zusammenfassung:	The tool (1) has a control device provided in a drive circuit for operation of an electromotor (M) two rotation directions. The control device independently determines a selected rotation direction of the electromotor for a next operating cycle depending on a control variable. The electromotor is started in the rotation direction that is assigned with a value of the control variable at a starting operation of the electromotor, where the value of the control variable is independently redetermined for the next operating cycle.
