Installation
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 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. 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. For mounting
dimensions, refer to http://www.baldor.com/products/servo_motors.asp and provide
adequate clearance.
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.
