Motor Size, Compliance, & Installation
EQP Global IEC Series Low-Voltage 50/60 Hz Metric Motor
5. Measure the alignment and, using shims, con-
tinue to adjust as required.
Bedplate Installation and Leveling
Install the bedplate onto the foundation by
performing the following procedure.
1. Place 19 mm – 25.4 mm (¾" – 1") thick iron
wedges onto the foundation at the motor mount-
ing location.
Note: The iron wedges shall cover at least
75% of the motor mounting footprint.
2. Position the iron wedges equally spaced and
close to the foundation bolts.
3. Place the bedplate onto the foundation.
4. Use the iron wedges to position and level the
bedplate onto the foundation.
5. Secure the bedplate onto the foundation using
the foundation bolts.
6. Torque the foundation bolts securely.
The 19 – 25.4 mm (¾" – 1") of space between the
foundation and the bedplate is to be filled with
grout.
DO NOT remove the wedges when grouting the
bedplate — wedges are to be sized for the
application so as not to interfere with the grout form.
Grouting
The foundation mounting surface must be rough
and clean to provide good grout anchorage. The
grout shall be of the non-shrinking type.
Apply the grouting between the foundation and the
bedplate by performing the following procedure.
1. Wash the top of the foundation.
2. Where possible, build a form (border) that
extends 50.8 mm (2") around the periphery of the
bedplate area. The form is used to contain the
grout during the grout application.
3. Pour and pack in the grout.
4. Grout in by building a low dam around the inside
and outside of the bedplate. Where possible,
allow grout to extend beyond the bedplate periph-
ery 50.8 mm (2") on all sides.

5. Pack the grout to a height of 12.7 mm (½") above
the underside of the bedplate.
Note:
Too deep of a grouting will cause
difficulty if the motor must be removed
at a later date.
Motor Coupling
Motor Coupling and Alignment
Use shims to aid in the motor-to-base leveling.
Couple the motor using a flexible coupling if
possible.
Roller bearings may be used with flexible couplings
— ensure proper alignment. Ball bearings are
recommended for direct coupled applications. Rigid
couplings require extra allowance for thermal shaft
growth toward the coupling. Skidding noise may
result from the combination of internal bearing
clearances and alignment tolerances. DO NOT
RUN A ROLLER BEARING WITHOUT A LOAD
CONNECTED.
To give the motor proper support, it is important that
the base and shims combine to create a level and
stable platform.
Motor coupling can be measured using a dial
indicator or using a feeler gauge. The preferred
method is with the dial indicator; both methods will
be discussed.
Rigid Coupling
Shaft Alignment
Extreme care must be taken to obtain correct shaft
alignment when using rigid couplings. Circular
concentric peripheral surfaces and the separation
between the faces of the two coupling halves must
fall within the range of 0.013 to 0.025 mm (0.0005"
to 0.001") when the two coupling halves are rotated
together.
The alignment may be checked by using a dial
indicator, or with the aid of a straight-edge and
thickness gauge or feelers as shown in
pg. 9
and
Figure 5. on pg.
10, respectively.
The preferred method of checking alignment is with
the dial indicator. Bolt the indicator to one of the
coupling halves and indicate the position of the dial
button on the opposite coupling half with a chalk
mark. Set the indicator dial to zero at the first
position and then rotate both halves of the coupling
to a new position where a reading is to be made. All
