4 Technical Data
4.1 Definition of Parameters
4.1.1 60K and 100K Parameters
The speed-torque curves and the technical data are specified for two different
temperature models.
● 60K temperature stroke on the housing and
● 100K temperature stroke on the winding
When selecting the technical data, observe the temperatures speci-
fied! The appropriate parameters are identified by 100K or 60K.
The motor data and characteristic curves for IndraDyn S motors are determined
under the following conditions:
● Environmental temperature approx. 40°C
● Insulated structure (aluminum flange)
● Permissible temperature increase on the housing ΔT = 60K
● 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
The motor data and characteristic curves for IndraDyn S motors are determined
under the following conditions:
● Environmental temperature approx. 40°C
● Structure not insulated (attachment to steel flange, LxWxH = 450x30x350
or 120x40x100)
● Permissible temperature increase on the winding ΔT = 100K
● 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
The machine accuracy can be negatively affected by an increased
linear expansion during 100K operation. We recommend using 60K
data when projecting systems.
4.1.2 Operating Mode
IndraDyn S motors are documented according to the inspection criteria and
measurement procedures of EN 60034-1. The specified characteristic curves
correspond to operating modes S1 or S3.
