MTC Motors 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.

C-Flange Kits for MTC EPAct Three-Phase Motors
C-Flange Kits
Any IronHorse MTC EPAct T-frame cast-iron motor from
1-300hp can be converted to C-face mounting by using a
cast iron C-flange kit. These kits are field installable and
include the C-faces and mounting bolts.
C-Flange Dimensions
C-flange dimensions are shown in Chapter 2 (Mounting &
Initial Startup) along with TC-frame motor dimensions.
MTA T-Frame C-Flange Kit
Authorized EASA service centers are equipped with the necessary equipment to quickly and
inexpensively install C-Face kits. Visit the EASA website at www.easa.com to find the nearest
authorized service center. C-faces must be installed by an EASA motor shop in order to maintain the
motor warranty.

S ngle-Phase Motors - Features and Specifications
IronHorse® single-phase farm-duty motors are available from
2hp to 5hp. All models have a TEFC housing (steel frame
with iron end bells) that is fully gasketed for use in dirty
environments. All motors are NEMA L design.
All models include a class-10 manual-reset locked-rotor
thermal protector (motor thermal overload protection must
be provided separately).
We recommend disconnecting power to the motor before reseting the
thermal protector. Do not reset more than twice in succession. The
motor must cool to 40°C (104°F) before a third reset.

Capacitors and Centrifugal Switches for IronHorse® Single-Phase Motors
Single phase motors use capacitors to provide starting torque when power is first applied to the motor.
When the motor begins to turn, the start capacitor is no longer need and is taken out of the circuit by a
centrifugal switch. In addition to the start capacitor, 1-1/2 hp and larger IronHorse single-phase motors
have run capacitors to allow the motor to develop higher running torque and greater efficiency. Run
capacitors also help improve the motor power factor.
