F1 and F2 Mounting
F1 and F2 mounting refers to the location of the junction box on an AC motor. Several models of
IronHorse® motors can be converted from F1 to F2 mounting.

To minimize the potential of damage to any internal component, use caution when pulling the rotor from the
frame when converting an IronHorse® motor from F1 to F2 mounting. Authorized EASA service centers are
equipped with the necessary equipment to quickly and inexpensively convert motor mounting. Visit the EASA
website at www.easa.com to find the nearest authorized service center. Conversion from F1 to F2 mounting must
be performed by an EASA motor shop in order to maintain the motor warranty.

1) TC-frame motors have the same minimum sheave diameters as the
comparable T-frame motors.
2) Sheave dimensions are based on the following:
a) Motor nameplate horsepower and speed.
b) Belt service factor of 1.6 with belts tightened to the belt manufacturers
recommendations.
c) Speed reduction of 5:1.
d) Mounting of sheave on motor according to sheave manufacturers
instructions.
e) Center-to-center distance between sheaves approximately equal to the
diameter of the larger sheave.
f) Calculations covered by the standards listed in notes 3 & 4 below.
3) As covered by IP-20; Specifications for Drives Using Classical V-Belts and
4) As covered by IP-22; Specifications for Drives Using Narrow V-Belts and

Chapter 5: Reference Information
Decibel Levels
The decibel (sound) level of an IronHorse® motor should be measured after initial startup, after 30 days,
and after six months of use. Decibel levels should remain fairly consistent and can be an indication
of misalignment and premature bearing wear. If the measured decibel level for your IronHorse model
exceeds the value listed below by more than 10%, contact AutomationDirect or a local motor service
technician found at www.easa.com.
