PROBLEM TO BE SOLVED: To provide a method for operating an electric motor in a work apparatus with which a user can work at a stable operating point at an arbitrarily rotation number over a wide operating range of the electric drive.SOLUTION: An electric motor is operated using a power characteristic curve 30, 31, 32, 33 between a lower rotation number of the electric motor and an upper rotation number of the electric motor, where the power characteristic curve is configured to cause a power characteristic to have a pronounced maximum M and an operating plateau AP within an operating rotation number range of the work apparatus. In this operation, the position of the operating plateau AP can be shifted in accordance with the rotation number n of the electric motor. |
