    • The invention relates to an electric motor having a stator and a rotor. The electric motor also comprises a controller, wherein the controller is connected to the stator and/or rotor, and is designed for applying current to the stator and/or rotor for rotating the rotor. According to the invention, the controller comprises a pulse width modulator designed for controlling a power output of the electric motor, in order to generate a predetermined number of different current application patterns. The current application patterns each represent a power output of the electric motor, and preferably comprise a time sequence of current pulses, each having a current pulse duration. The controller is designed for applying current to the electric motor according to at least two different current application patterns for actuating the electric motor during a time interval of actuation, such that a power output of the electric motor in the time-based average of the time interval of actuation, in particular from the beginning to the end of the time interval, is different from the power outputs represented by the current application patterns in the time interval of actuation.

    • The invention relates to a method for producing a micromechanical component (100) that comprises at least one cavity (110) and one functional element (12) at least partially disposed in said cavity (110) and/or one functional layer (13a, 13b, 13c) at least partially disposed therein. The invention further relates to a micromechanical component (100) produced according to the inventive method. The aim of the invention is to reduce the production costs for such a micromechanical component. To this end, the functional element (12) and/or the functional layer (13a, 13b, 13c) is provided with a first protective layer (41; 71) at least in a zone that adjoins a first sacrificial coating (52) that temporarily occupies the space of the cavity (22) subsequently formed in one or more etching steps. The material of the first protective layer (41) is selected in such a manner that at least one etching method and/or etching agent etching or dissolving the first sacrificial coating (52) does substantially not corrode the first protective layer (41; 71) or corrodes it only at a reduced etching rate in relation to the first sacrificial coating (52).
