Features

5.2.1.1 Overview
1FT6 motors can be combined with planetary gearboxes to form compact coaxial drive units.
The gearboxes are flanged directly to the drive end of the motors.
When selecting the gearboxes, ensure that the permissible speed of the gearbox is not
exceeded by the maximum speed of the motor. In the case of high operating frequencies, an
allowance of f
The frictional losses of the gearbox must always be taken into account in planning.
The gearboxes are only available in non-balanced design.

High efficiency:
Minimum torsional backlash:<= 4 arcmin single-stage
Power transmission from the central sun wheel to planetary wheels.
No shaft deflections in the planetary wheel set due to the symmetrical force distribution.
Very low moment of inertia and hence short acceleration times of the motors.
Output shaft bearings dimensioned for high cantilever and axial loads with preloaded
tapered-roller bearings.
The gearboxes are connected to the motor shaft via an integrated clamping hub. A plain
motor shaft end is necessary for this purpose. Radial eccentricity tolerance N to DIN
42955 and vibration severity grade N to EN 60034-14 are sufficient. The motor flange is
adapted via adapter plates.
Output shaft of gearbox exactly coaxial with the motor.
The gearboxes are sealed (seal between the gearbox and motor) and filled with oil at the
factory. They are lubricated for life and sealed. Gearboxes of frame sizes SP060S to
SP180S are suitable for all mounting positions.
For gearboxes, sizes SP210 and SP240 the quantity of oil in the gearbox depends on the
mounting position. The mounting position has to be specified when ordering.
Gearbox degree of protection IP65 (IP64 for frame sizes SP210 and SP240).
Small dimensions.
Low weight.
