Handling
The motor should be lifted using the lifting lugs or eye bolts provided.
1.
Eyebolts or lifting lugs are intended
for
lifting the motor only with the standard factory installed
accessories such as tachometer, etc., the lifting means on the motor must not be used to lift the
motor plus additional equipment such as gears, pumps, compressors, or other driven equipment.
The lifting means on the motor cannot be used to lift assemblies of motor and other equipment
mounted on a common base.
2. In all cases, care should be taken to assure lifting in the direction intended in the design of the lifting
means. Lift using all lugs provided. Likewise, precautions should be taken to prevent hazardous
overloads due to deceleration, acceleration or shock forces. Angle of lift with rope or chain should
never be less than 45 degrees from the horizontal.
Storage
Do not unpack until ready for use. If the motor is not put into service immediately, the motor must be
stored in a clean, dry and warm location. Several precautionary steps must be performed to avoid motor
damage during storage.
Caution: Sleeve bearing motors are shipped without oil. To avoid motor damage, do not rotate the shaft
until you have filled the oil reservoirs to the proper level with recommended lubricant.
1. The motor should be inspected periodically and the insulation resistance checked and recorded
monthly (see Checking Insulation Resistance in section 3). If there is a significant change in
insulation resistance, it should be investigated and corrective action should be taken. Consult your
local Baldor District office for additional data.
2. Do not lubricate bearings during storage. G − Series TEFC anti − friction bearing motors are shipped
with the proper amount of grease in each bearing.
3. At 30 day intervals, remove only enough packing to expose the shaft and remove the shaft shipping
brace, rotate the shaft (by hand) 10 to 15 revolutions. This distributes the grease, preventing bearing
corrosion due to condensation, or to the presence of contaminating gases near the motor. After
rotating the shaft replace protective packing and shaft shipping brace.
4. If the storage location is cold, damp or humid, the motor windings must be protected from moisture.
This can be done by applying power to the motors’ space heater (if available) while the motor is in
storage.
5. If the motor is stored and directly exposed to weather conditions, it is important that the bearing
grease be inspected for the presence of water at the grease drain. If the grease is contaminated with
water, the motor must be disassembled, grease removed from the bearing(s) and housing(s) and
bearing(s) inspected for corrosion. If corrosion is present, the bearing(s) must be replaced. If there is
no corrosion, repack the bearing(s) / housing(s) with grease as instructed on page 13.
6. G − Series motors with oil lubricated sleeve bearings are tested using an oil containing a rust inhibitor.
This additive protects the bearings and associated structural parts from rust and corrosion. Prior to
shipment the oil is drained. A thin film of oil remains on the vital parts providing short term temporary
rust protection.
As soon as the motor has been received, the bearing oil reservoir should be filled to the required oil
level and with the proper oil lubrication. (See Bearing Lubrication for proper type).
Unpacking
Each Baldor motor is packaged for ease of handling and to prevent entry of contaminants.
1.
To avoid condensation inside the motor, do not unpack until the motor has reached room
temperature. (Room temperature is the temperature of the room in which it will be installed).
The packing provides insulation from temperature changes during transportation.
2. When the motor has reached room temperature, carefully remove the motor from packaging.
Lifting provisions are provided as eyebolts or cast lifting lugs located on top of the motor.
Place a lifting hook in each of the lifting means provided and carefully lift the motor from its packing.
Use a hoist with adequate capacity.
