Page 6: General Information
This manual describes general guidelines that apply to most of the motor products shipped by Baldor. If you have a question about a procedure or are uncertain about any detail, Do Not Proceed. Please contact your Baldor distributor for more information or clarification. -

2. Verify that the part number of the motor you received is the same as the part number listed on your purchase order. Lifting Magnet Generators Treat Baldor lifting magnet generators like motors during installation or maintenance. Generally, they have standard compound self-excited fields. Standard magnetism is for counter-clockwise rotation (facing the drive end of the motor). -
Page 8: Handling
Note: Remove motor from containers when heaters are energized, reprotect if necessary. 3. Measure and record the resistance of the winding insulation every 30 days of storage. a. If motor insulation resistance decreases to less than 5 Meg ohms, contact your Baldor District office. -
Page 9: Removal From Storage
A decrease in resistance indicates moisture in the windings and necessitates electrical or mechanical drying before the motor can be placed into service. If resistance is low, contact your Baldor District office. 3. Regrease the bearings as instructed in Section 3 of this manual. -
Page 10: Installation & Operation
Do not over tension belts. Excess tension may damage the motor or driven equipment. 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). -
Page 11: Doweling & Bolting
Doweling & Bolting After proper alignment is verified, dowel pins should be inserted through the motor feet into the foundation. This will maintain the correct motor position should motor removal be required. (Baldor motors are designed for doweling.) 1. Drill dowel holes in diagonally opposite motor feet in the locations provided. - Page 12 B1, B2, B3, etc. Space Heater (Brake) H1, H2, H3, H4, etc. Brake Interlock Switch BS1, BS2, BS3, etc. Figure 2-1 Encoder Connections Color Codes for Optional Baldor Encoder Cable Electrically Isolated Encoder COMMON Standard Receptacle MS3112W12−10P Standard Plug MS3116J12−10S Thermostats The thermostat is a pilot circuit device used in a protective relay circuit.
- Page 13 Blower Ventilation System Before loading a force-ventilated motor, be sure that the blowers, cooling fans, or central air supply systems are operating properly to supply cooling air to the motor. Air filters should also be in place. If you energize the main fields with the motor at standstill, the blowers or external cooling systems must be left on.

Page 16: Maintenance & Troubleshooting
Section 3 Maintenance & Troubleshooting General Inspection Inspect the motor at regular intervals, approximately every 500 hours of operation or every 3 months, whichever occurs first. Keep the motor clean and the ventilation openings clear. The following steps should be performed at each inspection: 1. -
Page 17: Lubrication & Bearings
Thoroughly clean bearing & cavity before adding grease. ** Special low temperature grease is recommended (Aeroshell 7). Different brushes may also be required. Contact your local Baldor district office or an authorized Baldor service center for technical assistance. Table 3-4 Lubrication Interval Multiplier... -
Page 18: Lubrication Procedure
Be sure that the grease you are adding to the motor is compatible with the grease already in the motor. Consult your Baldor distributor or an authorized service center if a grease other than the recommended type is to be used. -
Page 19: Brush Replacement
Brush springs should have equal tension. Only brushes of the same size, grade and shape as those originally supplied should be used. All motors have their brushes set on neutral before leaving Baldor’s factory. After replacing the brush holder, realign it to the factory neutral mark. -
Page 20: Carbon Brushes For Special Operating Conditions
Do not change brush grades or the number of brushes per pole. Doing so may void the warranty and make the motor unsafe. Contact your local Baldor district office or an authorized Baldor service center for technical assistance. -

Do not change brush grades or the number of brushes per pole. Doing so may void the warranty and make the motor unsafe. Contact your local Baldor district office or an authorized Baldor service center for technical assistance. Blowers & Filters Do not use silicone RTV around DC motors as commutator surface damage can occur. -

Page 26: Reflash Instructions
Reflash Instructions Instructions to reflash the residual magnetism for Lifting Magnet Generators only. These generators are self−exciting. If voltage will not build up, it is possible the residual magnetism is insufficient to initiate excitation. This procedure is to restore sufficient residual magnetism to self excite. Note: Loss of residual magnetism can be caused by misconnection (reversing the connections) of F1 and 1. - Page 27 3-12 Maintenance & Troubleshooting MN605 Artisan Technology Group - Quality Instrumentation ...
