Characteristics
4.1.1
General Information
The speed-torque curves and the technical data are specified for different
motor overtemperatures.
The motor data and characteristic curves are determined using MKE motors
under the following conditions:
●
Environmental temperature max. 40 ℃
●
Insulated structure (aluminum flange)
●
In case of motors with the optional holding brake, the data are always
specified for motors with a holding brake.
●
Motors with radial shaft sealing ring

Operating Modes
The motors are documented according to the test criteria and measuring
methods of EN 60034-1. The specified characteristic curves correspond to
operating mode S1 or S3.
