Figure 5-2
Surface to be sealed when mounting an IEC motor
Procedure
1. Clean the surfaces to be sealed on the motor and coupling lantern.
2. Coat the entire surface with an appropriate sealing compound.
3. Flange-mount the motor to the coupling lantern and secure it using the prescribed torque.
4. Apply a suitable protective coating to the interface and the entire geared motor to prevent corrosion.
The general tolerance for the tightening torque is 10 %. The tightening torque is based on a friction coefficient of μ = 0.14.
