GEI-M1011A I. GENERAL INFORMATION A. How to Properly Use This Instruction Manual This manual has been written to assist the user with proper procedures when handling, installing, operating and maintaining the equipment. All of the safety warnings and instructions in this book must be followed to prevent injury to personnel. The installation and maintenance manual must be kept for future reference during installation, operation and maintenance.
GEI-M1011A C. Safety Precautions WARNING: High voltage and rotating parts can cause seri ous or fatal injuries. Installation, operation, and mainte- nance of electric machinery should be performed by qualified personnel. Familiarization with NEMA Publication MG-2, Safety Standard for Construction and Guide for Selection, Installation and Use of Electric Motors and Generators, the National Electrical Code, and sound local practices is recommended.
GEI-M1011A D. INTRODUCTION This instruction book applies to motors with Totally Enclosed Fan Cooled enclosures as defined by NEMA. General Electric high thrust vertical motors covered by these instructions are carefully constructed of high quality materials and are designed to give long and trouble-free service when properly installed and maintained. These motors are generally used to drive pumps.
GEI-M1011A III. INSTALLATION to prevent the entrance of moisture, dust, or dirt during storage and installation. Precautions are taken by the factory to guard against corrosion. The machined parts are slushed to prevent rust during shipment. Examine the parts carefully for rust and moisture if the equipment is to be stored and reslush where necessary. WARNING: Installation should be in accordance with the National Electrical Code and consistent with sound local practices.
GEI-M1011A C. Alignment of Solid Shaft Motors 2. Self-Release Couplings Accurate mechanical lineup is essential for successful operation. Mechanical vibration and roughness when the motor is running may indicate poor alignment. In general, lineup by straight edge across, and feeler gages between coupling halves is not sufficiently accurate. It is recommended that the lineup be checked with dial indicators. The space between coupling hubs should be maintained as recommended by the coupling manufacturer.

This type of coupling does not have the self-release feature and allows reverse rotation. XH See the self-release coupling shown to the left of the motor center line in Figures 4-6 which is applicable to bolted couplings except that the headless drive pins are replaced by bolts as explained above. 50.8 mm (2.00 in.) 57.15 mm (2.
GEI-M1011A A very rapid decrease in speed can result in acceleration forces great enough to prevent the pins from dropping. This condition is further aggravated when the pins become dirty and their action sluggish. If the time from shutdown (the instant the “stop” button is pressed) to zero speed is greater than two seconds, operation will be satisfactory. When installing a non-reverse coupling do not use lubricant.
GEI-M1011A (Delta) Low Voltage F. Lubrication Motors with oil lubricated bearings (324-5011 frames) are shipped without oil. Before starting the motor, fill each reservoir to the standstill level shown on the sight gage. Be careful to keep dirt out of the lubricant and bearing housing. Use only the oil specified on the lubrication nameplate or the lubrication instruction supplied with each motor. See Relubrication, Table 2 and Lube Nameplate for oil grade and viscosity and further instructions.
GEI-M1011A A. Steps Prior to Initial Start-Up After a Long Idle Period 1. Check insulation resistance as indicated in the caution above.
GEI-M1011A 3. Examine the motor for loose objects or debris which may have accumulated and remove any foreign material. 5. Check line voltage on all three phases to be sure it is balanced and within 10% of motor rated voltage with motor drawing load current. 4. If possible, turn the rotor by hand to be sure that it rotates freely. 6. Check the operating current against the nameplate value. Do not exceed the value of nameplate amperes X service factor (if any) under steady continuous load.
GEI-M1011A In addition to a daily observation of the overall condition, it is recommended that a regular inspection routine be set up to check periodically the following items: 1. General Cleanliness 2. Insulation and Windings 3. Lubrication and Bearings 4. Coupling Bolt Tightness Bolts on both bolted couplings and non-reverse couplings should be checked periodically to be sure they are tight. See Required Bolt Torques. D. Relubrication 1.

GEI-M1011A 5. Insert brush into relief hole. While the motor is still warm, add grease with a hand operated grease gun until fresh grease appears on the end of the brush or until grease has been added up to the amount listed in Table 4. Do not exceed recommended amounts listed in Table 4. To obtain optimum results, use Exxon POLYREX EM (General Electric Specification D6A2C23) polyurea grease should be used for relubrication, unless a special grease is specified on the motor nameplate.
GEI-M1011A periods. See Figure 10. This puts an up thrust load on the lower guide bearing. The springs (and spacers if a full circle of springs is not used) are located in a “chair” which is in turn located in the upper end shield. This “chair” and the captive springs can be removed and cleaned as a unit if necessary; it should not be taken apart unless it or a spring is damaged. above the upper bearing. This adjustment is made at the factory and need not be disturbed on a new motor.
GEI-M1011A Angular-contact bearings which are to be stacked together should have their high points of eccentricity (indicated by a burnished spot on the inner race) lined up. All bearings should be of the same manufacturer and of the type that permits stacking. by using wrench on hex fitting at inner end of C.
GEI-M1011A Suction should be used to remove dirt and dust particles from windings to avoid driving particles into the windings and damaging the coils. Although cleaning with water and detergent is the preferred method, solvent cleaning may be used when heat drying facilities are not available. CAUTION: Care must be taken to make sure that the air supply is dry and that excessive air pressure is not used. Generally a pressure of not more than 200 kPa (30 PSI) is recommended.
