■
Refer to the drawing below for correct centering of the motor shaft and the target machinery.
Please note when using a rigid coupling that even a slight mistake in centering can damage
the output shaft.
■
Do not apply any shocks on the servo motor shaft because precision equipment, encoder is
directly connected to it. If it is absolutely necessary to hit the motor for position adjustment or
other reasons, use a rubber or plastic hammer and hit the front flange area.
■
For mounting to a machine, create accurate enough mounting holes for smooth coupling of
the motor flange rabbet. The mounting surface should be flat, otherwise damage to the shaft
or the load may occur.
■
Use the screw at the end of the shaft for installing parts such as the gear, pulley, or coupling,
to avoid shock.
■
Tapered servo motor shafts transmit the torque via the tapered surface. Make sure the key fits
without rattling. The tapered surface contact should be no less than 70%.
Measured at all 4 locations, the
difference between the maximum and
the minimum should not exceed
3/100mm.
