8.0 - OPERATING SPEED
Input speed
n 1 [rpm]
The speed the gearbox is driven at. The value is coincident with the motor speed if this is directly
connected to the gearbox. In case the gearbox is driven through an external transmission, the
gearbox input speed is the speed of the motor divided by the reduction of the external transmission.
In this case, it is recommended that the input speed be lower than 1750 rpm.
When selecting the prime mover, 4-pole motor, or lower speed motors, should be preferred.
Output speed
n 2 [rpm]
It is calculated from drive speed « n 1 » and gear ratio « i », as per the following equation:
