BRS3 3 Technical Data
3-phase stepper motor 43
3.8.2 Shaft load
The following conditions apply:
• Speed of rotation n = 600 min
-1
• Ambient temperature = 40°C (approx. 80°C bearing temperarture)
• 100% duty cycle at nominal torque
If these conditions are met the maximum forces shown in the table below
may act on the shaft (however, not simultaneously):
