Installation & Operation
Installation & Operation 2-1 MN605
Overview
Installation should conform to the National Electrical Code as well as local codes and
practices. When other devices are coupled to the motor shaft, be sure to install
protective devices to prevent future accidents. Some protective devices include,
coupling, belt guard, chain guard, shaft covers etc. These protect against accidental
contact with moving parts. Machinery that is accessible to personnel should provide
further protection in the form of guard rails, screening, warning signs etc.
Location
The motor should be installed in an area that is protected from direct sunlight, corrosives,
harmful gases or liquids, dust, metallic particles, and vibration. Exposure to these can
reduce the operating life and degrade performance. Be sure to allow clearance for
ventilation and access for cleaning, repair, service and inspections. Ventilation is
extremely important. Be sure the area for ventilation is not obstructed. Obstructions will
limit the free passage of air. Motors get warm and the heat must be dissipated to prevent
damage.
These motors are not designed for atmospheric conditions that require explosion proof
operation. They must NOT be used in the presence of flammable or combustible vapors
or dust.
TEFC motors can be used for indoor or outdoor standard service. They cannot be used
outdoors where they would be exposed to freezing rain. Standard TEFC motors are not
designed for atmospheric conditions requiring explosion-proof operation, such as
flammable or combustible vapors or dust.
Mounting
The motor must be securely installed to a rigid foundation or mounting surface to
minimize vibration and maintain alignment between the motor and shaft load. Failure to
provide a proper mounting surface may cause vibration, misalignment and bearing
damage.
Foundation caps and sole plates are designed to act as spacers for the equipment they
support. If these devices are used, be sure that they are evenly supported by the
foundation or mounting surface.
After installation is complete and accurate alignment of the motor and load is
accomplished, the base should be grouted to the foundation to maintain this alignment.
The standard motor base is designed for horizontal or vertical mounting. Adjustable or
sliding rails are designed for horizontal mounting only. Consult your Baldor distributor or
authorized Baldor Service Center for further information.
Alignment
Accurate alignment of the motor with the driven equipment is extremely important.
1. Direct Coupling
For direct drive, use flexible couplings if possible. Consult the drive or
equipment manufacturer for more information. Mechanical vibration and
roughness during operation may indicate poor alignment. Use dial indicators to
check alignment. The space between coupling hubs should be maintained as
recommended by the coupling manufacturer.
2. End-Play Adjustment
The axial position of the motor frame with respect to its load is also extremely
important. The motor bearings are not designed for excessive external axial
thrust loads. Improper adjustment will cause failure.
3. Pulley Ratio
The pulley ratio should not exceed 8:1. Consult your Baldor distributor or
authorized Baldor Service Center for further information.
4. Belt Drive
Refer to NEMA MG 1 section 14.07 or Baldor application section for the
application of pulleys, sheaves, sprockets, and gears. Align sheaves carefully to
minimize belt wear and axial bearing loads (see End-Play Adjustment). Belt
tension should be sufficient to prevent belt slippage at rated speed and load.
However, belt slippage may occur during starting. Do not over-tension belts.
