For IEC frame, select the lower value of the equivalent NEMA frames.
If the application calls for significant thrust loads, please contact Techtop to
determine if you have the correct motor for your application.
Note
s:
1. Overhung loads are considered to include belt tension and sheave weight.
2. Belt loads considered to act in a vertically downward direction.
3. To determine load at shaft end subtract 15%.
4. Overhung load radial limits are based on a bearing L-10 life of 26,280 hours.
5. Overhung load limits don't include effects of any unbalanced magnetic pull.

12. CONDENSATE DRAINS

Many Techtop motors come standard with one way sintered brass breather drains.
These drains allow the motor to expel liquids from the casing without allowing liquid
to enter the motor. Drains may require periodic maintenance to keep them clean
of debris and flowing freely. Occasionally, remove the brass drains and wash them
thoroughly. Eliminate any built up debris which may be impeding their operation.
For motors which are equipped with rubber plugs in their condensate drain holes,
be sure to remove the plug (i.e. especially if the motor is installed in a location where
condensate build up is likely).
In all instances, ensure that the drain is in the lowest portion of the motor. Some
motors may require rotation of the end plates (i.e. if the mounting location is not
a typical horizontal mounting).
