摘要： A method for the noise-reduced operation of a switched reluctance motor with a reluctance motor assembly. The assembly includes the switched reluctance motor; —a control and evaluation unit; —a data memory; —a current regulator; —a rotor angle sensor; and —a torque evaluator. The switched reluctance motor includes a stator, a rotor and motor coils. The size of the current applied to the motor coils is stored in a value table in the data memory for different rotor angles. An actual torque is detected, and a deviation between a setpoint torque and the determined actual torque is determined. On the basis thereof, the current values are recalculated. The recalculated current values are written into the value table and define the basis of the next run.

摘要： A vibration and noise-reduced electric-motor device for an electrical household appliance or an electrical sliding roof. The invention includes a method for the vibration and noise-reduced operation of an electric-motor device. The electric-motor device has an electric-motor assembly, a main body, and a driven group of accessories. The electric motor assembly includes an electric motor, a control and evaluation unit, a data memory, a current regulator, a rotor angle sensor and a torque evaluator. The electric motor has a stator, a rotor and motor coils. In the method, a setpoint current stored in a value table in the data memory is applied to the motor coils in accordance with the rotor angle. The torque deviation resulting at the setpoint current, between the setpoint torque and the actual torque is determined, and an optimized new setpoint current value is calculated by interpolation and is written into the value table.

摘要： A method for the optimized operation of a BLDC motor with a BLDC motor assembly that includes the BLDC motor;—a control and evaluation unit;—a data memory;—a current regulator;—a rotor angle sensor; and—a torque evaluator. The BLDC motor includes a stator and a rotor. The rotor includes excitation magnets, and the stator has stator coils. A current is applied to the stator coils. The size of the current is defined in a value table depending on the rotor angle. The current values in the value table are continually optimized in accordance with a deviation between a setpoint torque and a determined actual torque.
