Operating Area of motor
The display shows the range of possible operation points of the drives at a given ambient temperature of 22°C.
The diagram indicates the recommended speed in relation to the available torque at the output shaft.
It includes the assembly on a plastic- as well as on a metal flange (assembly method: IM B 5).
The nominal voltage linear slope describes the maximal achievable operating points at nominal voltage. Any points of operation above this linear slope will require a supply voltage Umot > UN.
