For P = constant from n
N
= 1500 rpm to n
max
= 6300 rpm a constant power control range
greater than 1:4 is possible.
Motor with selector gearbox
For gearbox stage i
1
= 4 and i
2
= 1 a constant power control range of greater than 1:16 is
possible (n
N
' = 375 rpm to n
max
= 6300 rpm).
Vibration levels
Motor + gearbox: Tolerance R (acc. to DIN ISO 2373)
This is also valid if motor tolerance level S is ordered.
Information regarding spindle applications
● The following advantages are obtained by locating the gearbox outside the spindle box:
● Gearbox vibration is not transferred.
● Separate lubricating systems for the main spindle (grease) and selector gearbox (oil).
● No noise and no temperature fluctuations caused by the gearbox pinion wheels in the
spindle box.
● Instead of using belts, the drive power can also be transferred from the gearbox output
using a pinion (on request) or co-axially through an compensating coupling.
