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
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.
