GENERAL GUIDELINES FOR MOUNTING VARIABLE SPEED AC OR DC MOTORS<br />
SCOOP MOUNT ACCESSORY<br />
1. This is a soft mounting of the motor.<br />
2. The benefits obtained by using this accessory are low<br />
cost and isolation of the reducer support structure<br />
from the motor vibration.<br />
3. This motor mount was designed for use with a<br />
constant speed motor at 1750 RPM. Use of motors<br />
with lower base speeds increases the chance of<br />
producing resonance.Stiffening techniques within the<br />
scoop structure can increase the fundamental natural<br />
frequency about 20% which is generally enough to<br />
eliminate resonance should it occur.<br />
4. This accessory is NOT re<strong>com</strong>mended for variable<br />
speed DC or AC applications.<br />
5. Customers who prefer to use the scoop mount<br />
accessory to mount variable speed AC or DC motors<br />
must state on the face of the purchase order that they<br />
plan to support scoop and assume full responsibility<br />
for any vibratory or transient load induced by the<br />
motor. For re<strong>com</strong>mended scoop support, contact<br />
Reliance Electric and reference drawing #A31512.<br />

TOP MOUNT ACCESSORY<br />
1. This may be a soft or hard mounting of the motor<br />
depending on the size of the motor and the distance<br />
that the adjusting screws are extended.<br />

2. The benefits obtained by using this accessory are low<br />
cost, minimum floor space used for the motor/reducer<br />
assembly, and greater flexibility to obtain the required<br />
output RPM of the reducer than concentric coupling.<br />
3. This motor mount was designed for use with a<br />
constant speed motor at 1750 RPM.<br />
4. This accessory is NOT re<strong>com</strong>mended for variable<br />
speed DC or AC applications. Consult Reliance.<br />

HD BASEPLATE ACCESSORY<br />
1. This is a hard mounting of the motor.<br />
2. The benefits obtained by using this accessory are:<br />
a. resonance problems are minimized<br />
b. accurate assembly of motor/coupling/reducer<br />
can be done at the factory instead of the job site.<br />
Note: Alignment must always be rechecked at<br />
job site prior to start-up.<br />
c. large motors can be rigidly mounted to keep<br />
deflection under control and provide longer<br />
service life.<br />
3. This accessory is re<strong>com</strong>mended for large motors<br />
where the motor weight exceeds the reducer weight or<br />
700 lbs., and for variable speed DC or AC applications<br />
regardless of the motor weight. For mounting<br />
dimensions see page G3-39.<br />
