摘要： A method for the noise modulation of a three-phase synchronous electric motor driven using a vector regulation by means of a motor control unit. Actual values for the rotated current components id and iq may be obtained in an open-loop control system, where id corresponds to the magnetization current and iq corresponds to the torque-forming current of the synchronous motor. The actual values may be compared with predetermined reference target values, and the differences between the actual values and the reference target values may be converted into control variables to regulate the actual values (iq, id) to the reference target values. The magnetization current-forming current component (id) may be adapted using an acoustic controller to a desired acoustic state depending on an acoustic state that was measured by a measuring device and was transmitted to the motor control unit.

摘要： A variable speed drive for an electrostatic motor provides feedback control by conversion of measured current phases provided to the motor into a vector in a rotating rotor framework. This vector is used for evaluating corrective voltages and then reconverted to a non-rotating framework for application to the motor electrodes. Current-source drive circuits provide current stabilized outputs making such sophisticated control tractable.

摘要： A method for controlling a position of an actuating element, to which a restoring force is applied, in an actuator system having an electronically commutated electrical machine, includes controlling the position of the actuating element as a function of a predefined setpoint position specification and an actual position specification. A position control unit provides an actuating variable which is associated with a space vector with which a stator arrangement of the electrical machine can be driven. The method further includes applying a correction variable to the space vector in order to correct a space vector angle of the space vector; providing an auxiliary signal; varying the space vector angle of the space vector, which is defined by the actuating variable, by the auxiliary signal; and integrating a variable to give an integration value.

摘要： A current vector controlled synchronous reluctance motor and control method thereof, wherein the motor has a coil on each of the teeth. The coils form a U-phase winding, a V-phase winding and a W-phase winding. The phase windings receive a balanced three-phase current vector to induce closed magnetic field lines, such that the coils induce same magnetic poles adjacent to the rotor unit. Two short magnetic routes are formed along three adjacent teeth and the rotor unit. The efficiency of the reluctance motor is high.
