MAD / MAF Asynchronous Housing Motors
If a motor with this type of coolant port is ordered, all quick coupling parts are
included in the motor delivery. Based on the ambient conditions of the motor,
the user can select from two quick coupling mounting methods.
1. Method A: Lock nipple mounted on the motor side
2. Method B: Coupling mounted on the motor side
① Connection thread on the motor
②④⑦ Seal
③ Double nipple
⑤ Lock nipple
⑥ Coupling
⑧ Threaded adapter for tube
Fig. 6-10: Quick coupling mounting methods
Connect the double nipple to the coupling or the lock nipple. Then
screw the double nipple into the connection thread on the motor.
This procedure prevents the connection thread in the motor from
being stressed repeatedly.
When mounting the quick coupling, ensure
● that the seals are correctly positioned,
● that the following tightening torques between the individual coupling
components are kept,
