Patent ID: 8823312

Claim:
A method for operating an electric motor assembly for driving a fan, the electric motor assembly comprising an electric motor, and a motor control device for controlling the electric motor, wherein the motor control device can be set according to a characteristic curve ( 2 , 3 , 4 ) of the electric motor and of a characteristic ( 1 ) of the fan, and at least one of a power and a rotational speed of the electric motor is thereby adaptable, and the motor control device is set such that the characteristic curve ( 2 , 3 , 4 ) and at least one of the power and the rotational speed substantially matches at least one characteristic curve ( 2 , 3 , 4 ) and/or at least one of a power and a rotational speed of additional electric motors of the same type, the method including the steps of: determining a characteristic curve ( 2 , 3 , 4 ) of the electric motor and of a characteristic curve ( 1 ) of a device that can be driven by the electric motor after production, assigning the characteristic curve ( 1 , 2 , 3 , 4 ) and/or a proportionality factor, determined from the characteristic curve ( 1 , 2 , 3 , 4 ), to the electric motor by a marking of the electric motor, adapting the motor control device according to the characteristic curve ( 1 , 2 , 3 , 4 ) and/or the proportionality factor that is assigned to the electric motor by the marking, and operating the electric motor with the power and/or rotational speed adapted by the motor control device, characterized in that the motor control device is set such that the characteristic curve ( 2 , 3 , 4 ) and the power and/or rotational speed substantially matches at least one characteristic curve ( 2 , 3 , 4 ) and/or at least one power and/or rotational speed of additional electric motors of the same type.
