The torque-speed characteristics and technical data are given for two differ‐
ent temperature models.
● 60K temperature increase on the housing and
● 100K temperature increase on the motor winding
Observe the specified temperatures when selecting technical da‐
ta! The respective data are marked with 100K or 60K.
The 60K data are given for MSK motors under the following conditions:
● Ambient temperature 40 °C
● Insulated construction
● Maximum temperature increase on housing ΔT = 60K
● For motors with optional holding brake, data are always given for motors
with holding brake.
● Motors with radial shaft sealing ring
The 100K data are given for MSK motors under the following conditions:
● Ambient temperature 40 °C
● Construction not insulated (attachment to steel flange L×W×H
450×30×350; or L×W×H 120×40×100)
● Maximum temperature increase on the winding ΔT = 100K
● For motors with optional holding brake, data are always given for motors
with holding brake.
● Motors with radial shaft sealing ring
The machine accuracy can be negatively affected by increased
linear expansion in 100K‑operation. It is recommended to work
with 60K data when planning the systems.
