Motor Mount Installation
INTRODUCTION
The Falk Equi-Poised motor mount is an all steel weldment
that bolts directly to the drive housing of Falk
Shaft-Mounted
(Type JR), Flange-Mounted (Type JF) and Screw Conveyor
(Type JSC) Drives, as shown in Figure 1
This modern design provides a simple means of tensioning
V-belts or chains with adjusting screws Motor baseplates are
available from Factory pre-drilled for NEMA and IEC standard
foot-mounted motors within the rated capacity of the drive

ASSEMBLY INSTRUCTIONS
From Figure 2, determine which assembly is required
For minimum bearing loads on driven machine, minimum
shaft deflection and the most economical belt selections,
use the 6 o’clock mounting position, high-speed shaft
relative to the low-speed shaft, illustrated in Figure 1 The
motor/drive assembly can also be mounted in positions
shown in Figure 2 Always locate air vent at the top of
horizontal drives

OPTIONAL ASSEMBLY
The motor mount may be mounted on the
high-speed shaft end of FLANGE MOUNTED
DRIVES – JF (also SCREW CONVEYOR
DRIVES – JSC) if clearance over the trough end
permits) when increased motor mount clearance
is required at the driven machine Consult

plate support fasteners to torque values specified in
Table 2
a For Compact (C)
and Short (S)
