Motor Mounting
General Mounting Information
IronHorse® motors should be properly mounted to prevent premature motor and/or bearing failure. When
necessary, use motor shims to level the motor at all mounting bolt holes. Use proper diameter bolts of the
highest grade material available for the application. Use the chart below to select the correct size bolt for
each frame size.
A mounted motor must operate vibration free. Each motor installation should be checked for potential
vibration situations. On motors 100hp and up, we recommend that foundation studs be used to secure
the motor or slide base. Base shims should also be used when necessary for level mounting.

Note: In applications involving Direct coupling of the motor, drive end, bearing life, may be increased
by replacing roller bearings with equivalent ball bearings. Consult your EASA authorized motor shop for
details. Reminder: To maintain motor warranty, any motor work must be accomplished by your local
EASA authorized shop.

Chapter 2: Mounting and Initial Startup
Proper Installation Conditions
Care should be taken to make sure that an IronHorse® motor is mounted at least thirty inches from a wall
or structure that would prevent proper ventilation of the motor. The installation area should be free of
dust and smoke particles. Any air contaminate could inhibit proper operation of the motor fan.
If an IronHorse motor is to be installed in a high altitude or in a low temperature location, use the Altitude /
Ambient Temperature Derating chart below for proper motor sizing.

Example:
100hp @ 60ºC and 2000 Meters
100 / 0.64 = 156hp
The motor should be a 200hp motor.
Coupling Alignment
Correct coupling alignment is very important to the life of the motor. Coupling misalignment is the major
cause of motor bearing failure. In belt driven applications, pulleys should be installed correctly. Belt
tension, alignment, and wear should be checked at installation and at regular maintenance intervals.
Install motor couplings per the manufacturers instructions. Whenever possible, direct couple or flange
mount IronHorse motors in their application. Doing so can extend the bearing life greatly.
AutomationDirect offers C-face mounting kits for all PE and EPAct T-frame IronHorse motors. For a
complete list of mounting kits, see Chapter 4 (Accessories).

Motor Starter Information
IronHorse® general purpose motors can be controlled by across-the-line starters such as contactors and
manual motor starters. Under certain circumstances, three phase IronHorse motors can also be controlled
by AC drives. Refer to Chapter 5 (Reference) for more information about using AC drives with IronHorse
motors.
Use the following chart to help determine the appropriate across-the-line starter.

Locked Rotor Amps
All electrical components used in an IronHorse motor installation must be able to handle the maximum
current draw of the motor. When using a typical across-the-line starter, current is highest when power is
first applied to the motor. This is commonly referred to as locked rotor amps. Every IronHorse motor has a
locked rotor amperage code letter stamped on the motor nameplate either as “CODE” or “kVA Code”. This
letter applies to the locked rotor amp range value. See the motor “Performance Data” tables in Chapter 1
(Getting Started) for specific locked rotor amperage information.

AC Motors User Manual - 11th Ed. - 06/29/2022
Page 2-19
Chapter 2: Mounting and Initial Startup
Inspection Before Startup
1) Remove the shaft lock device if the motor was supplied with one.
2) Turn the shaft by hand and make sure the shaft turns freely. Listen for any unusual noises and feel
for any interruption in the shaft as it turns.
3) In all motors with serviceable bearings, check the grease level on both drive end and opposite drive
end bearings. Make sure the bearing cavities are filled with Mobil POLYREX® EM Polyurea grease.
MTCP2 motors should be greased using SKF, LGHP2 grease. Motors of frame size 250 and above have
grease fittings at the 12:00 o’clock position and relief ports at the 7:00 o’clock position. For these
motors, remove the plugs from the relief ports, and pump 12 to 13 pumps of grease into the grease
fittings. Some grease may come out of the relief port; this is normal. Reinstall the plug in the relief
port.
When replacing a T-frame end bell with a C-face end bell, transfer the grease fitting and
plug from the original to the new end bell.
4) Perform a final check on the installation of all parts in the assembly. Check the motor mounting
bolts, coupling, belt drive, C-face mount, alignment, etc.
5) Verify all electrical connections for the motor and starter. Refer to the motor diagram on the motor
nameplate. Make sure all terminal screws are tightened properly.
6) Make sure that all electrical components used in the installation are rated for the locked rotor
amperage.
7) Make sure the motor is properly grounded. Use the grounding lug provided in the motor terminal
box or on the mounting foot.
Initial Startup Inspection
1) At initial startup monitor the start-up voltage and the running voltage of the motor. The full load
voltage should never exceed the line voltage on the motor nameplate multiplied by the service
factor of the motor.
Example: 230 VAC x 1.15 = 264.5 VAC.
2) Check the full load running amperage (FLA) of the motor. The full load running amperage should not
be more than the amount indicated on the motor nameplate
3) Listen for any unusual noises at motor start-up and in the first hour of operation. Listen for any
unusual bearing noise in the drive end and opposite drive end of the motor. Abnormal bearing
noise can be an indication of a defective bearing or the motor grease could be low. If there is
abnormal noise in motors with serviceable bearings, shut down the motor and check the grease
level on both the drive end and opposite drive end.
Do not over grease the bearings. Over greasing motor bearings is a common cause of motor failure.
Large horsepower motors with roller bearings will typically be noisier than ball bearing motors at initial
motor start-up and in normal operation.

Chapter 3: Maintenance
Routine Maintenance
A routine maintenance schedule should be developed for every IronHorse® motor installation based on
the individual application. Motors installed in a harsh running environment should be serviced more
frequently than those installed in a clean, climate controlled area. Use the following to create a schedule.
1)
Clean the motor housing using a brush, soft cloth or compressed air. Pay special attention to the
cooling ribs on cast iron motors. Remove any dirt and dust from the fan and fan cover vents.
2)
Frequently monitor the bearing temperature on the motor. It should not exceed 60°C (140°F).
3)
Have the insulation checked periodically by an authorized motor specialist.
4)
(Applicable only for certain motors, per Note 1 of table shown below):
Lubricate the bearings using the schedule shown below.
5)
(Applicable only for certain motors, per Note 1 of table shown below):
Purge the bearing grease at least every six months on all motors with serviceable bearings. Replace
both the drive end and opposite drive end bearings at the end of their recommended running hour
life. Motors used in belt drive applications have a bearing life expectancy of 50,000 hours. Direct
coupled application motors have a bearing life expectancy of 100,000 hours.

4) For MTCP2 motors, use only SKF LGHP2 grease.
5) For MTDP motors, use Multemp SRL grease or equivalent.
