4.1.2 Parameters of the Characteristic Curves
The speed-torque curves and the technical data are specified in consideration
of the following conditions.
When selecting the technical data, observe the temperatures speci‐
fied!
The motor data and characteristic curves are determined using MKE motors
under the following conditions:
● Ambient temperature max. 40°C
● Insulated structure (aluminum flange)
● In the 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
Bosch Rexroth motors are documented according to the test criteria and meas‐
uring methods of EN 60034-1. The specified characteristic curves correspond
to operating modes S1 or S3.
