Abstract
An electric motor includes a signal device (5) for the display of at least two different operating conditions. For this, the signal device (5) includes six light diodes (A1-A6) which, with a running motor, are switched in a flashing manner synchronously to one another but shifted in time, so that they represent the rotational movement of the motor.
