Problems solved by technology

The disadvantage here is that either a complex adaptation of the respective motors has to be carried out, so that only a limited adaptation of the alternating loads of the electric motors is possible, or that the operating noise cannot be optimally reduced.

Abstract

The invention relates to a vibration- and noise-reduced electric-motor device, in particular an electrical domestic appliance and an electrical sliding roof. The invention also relates to a method for the vibration- and noise-reduced operation of an electric-motor device, the electric-motor device comprising an electric-motor assembly (I), a main body (II) and a driven working group (III), the electric-motor assembly (I) comprising an electric motor (1), a control and evaluation unit (2), a data memory (3), a current regulator (4), a rotor angle sensor (5) and a torque evaluator (6), and the electric motor comprising a stator (7), a rotor (8) and motor coils (9). According to the method, a setpoint current stored in a value table in the data memory (3) is applied to the motor coils (9) in accordance with the rotor angle. The torque deviation resulting, at said setpoint current, between the setpoint torque and the actual torque is determined, and an optimized new setpoint current value is calculated by means of interpolation and is written into the value table.

Description

technical field [0001] The present invention relates to a method for operating an electric device with damped and noise reduction and to a vibration and noise reduced electric device, in particular to a vibration and noise damped electric household appliance and a vibration and noise damped motor. Noise-reducing sliding or lifting roof. Background technique [0002] Electric appliances, such as electric domestic appliances and electric sliding or lifting roofs for motor vehicles, are known from the prior art. [0003] The noise development of electric household appliances and electric sliding or lifting roofs is particularly disadvantageous because the electric devices are operated directly in the immediate vicinity of the operator, in particular directly in the immediate vicinity of the head and ears. It is therefore known from the prior art to reduce the development of noise by encapsulating the electric motor with a sound-absorbing material. The disadvantage here is tha...
