Mounting

Motors must be mounted on a rigid, solid base or foundation. Poor base
construction may cause resonances in the motor/base assembly which can
result in bearing failure and other motor damage. All hold down bolts must
be the correct grade for the type of mounting and must be torqued to their
recommended value.

Table A Recommended Torque

Belted Drive

Motor slide bases or rails, when used, must be securely anchored to the
foundation with the proper bolts.

Important: The motor shaft and load shaft must be parallel and the sheaves

aligned. Refer to

“Motor Application Data” on page 8

.

Coupled Drives

Important: Flexible couplings must be used between the motor shaft and

the load shaft. Motor shaft and load shaft must be aligned to
values recommended for the specific coupling before coupling
is connected.

Important: Motors will operate successfully mounted on the floor, wall or

ceiling, and with the shaft at any angle from horizontal to
vertical. Special mountings, duty or thrust demands may,
however, require a different bearing system. Drive-end bracket
and/or outer caps can be rotated either 90 or 180 degrees to
conveniently locate grease fittings, or air outlet openings.
Handhole covers can be interchanged as necessary.

Important: Vertical mount drip covers are required to provide protection to

vertically mounted Drip-Proof motors. Stock motors and other
motors designed for horizontal mounting can be adapted for
vertical mounting by ordering vertical mount drip covers.
Self-ventilated frames cannot be mounted vertical shaft up and
retain the drip-proof feature due to louvers on the drive end
bracket.

Motor C-Face is intended for mounting auxiliary equipment such as pumps,
gears, etc. When mounted horizontally, these motors should be supported
by the feet and not by the C-Face. Installations requiring a horizontally
mounted motor without feet should use a D-Flange.

ATTENTION: Surface temperature of the motor enclosure may
reach temperatures which can cause discomfort or injury to
personnel coming into contact with hot surfaces. The user must
apply appropriate guards and/or shields to protect against
accidental contact with motor surface. Failure to observe this
precaution may result in personal injury.
