Overview
1FK7 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. For high operating frequencies an allowance
factor f
Synchronous Motors". The frictional losses of the gearbox must always be taken into account
when engineering geared drives.
The gearboxes are only available in a non-balanced design and with key.

High efficiency, single-stage: > 97 %
Torsional backlash, single-stage: ≤ 12 arcmin
Power transmission from the central sun wheel to the planetary pinions
No shaft deflections in the planetary gear set due to the symmetrical force distribution
The gearboxes are connected to the motor shaft via an integrated clamping hub. A plain
motor shaft end is required for this, while radial eccentricity tolerance N to DIN 42955 and
vibration severity grade N to EN60034-14 are sufficient. The motor flange is adapted via
adapter plates.
Output shaft of gearbox exactly coaxial with the motor
The gearboxes can be mounted in any position
The gearboxes are sealed (seal between gearbox and motor) and filled with grease in the
factory. They are lubricated and sealed for their service life.
