8.4 Shaft end

All 8JSA three-phase synchronous motor shafts comply with DIN 748 and are available with a smooth shaft end.

Motor options (ff) - Overview (order code)

see "Motor options (ff)" on page 18

Variants

Smooth shaft end

A smooth shaft end is used for a force-fit shaft-hub connection and guarantees a back-

lash-free connection between the shaft and hub as well as a high degree of operating

smoothness. The end of the shaft has a threaded center hole.

Keyed shaft end

A keyed shaft end is used for a form-fit torque transfer with low demands on the shaft-hub

connection and for handling torque in a constant direction.

The keyways for the 8JS three-phase synchronous motors conform to keyway form N1 per

DIN 6885-1. Form A keyed shafts that conform to DIN 6885-1 are used. Balancing motors

with keyways is done using the shaft and fitment key convention per ISO 1940/1, G6.3.

The end of the shaft has a threaded center hole that can be used to mount machine actu-

ators with shaft end cover plates.

Caution!

The shaft key can become dislodged during heavy reverse operation. In extreme cases, this can cause

the shaft end to break!
Preferably use smooth shaft ends with clamping elements.
