Safety Procedures This equipment contains hazardous voltages. Death, serious personal injury or property damage can result if safety instructions are not followed. The successful and safe operation of motors and generators is dependent upon proper handling, installation, operation and maintenance, as well as upon proper design and manufacture.
Inspect new motors for shipping invoice. examination before removing from cars or trucks. If damage or indication of rough handling is evident, file a claim with the carrier at once, and notify your Siemens sales representative. Remove only the shipping invoice.
The plant (or department) is shut down for 30 days. NOTE Storage requirements vary, depending on the length of storage and the climate. For storage periods of three months or longer or climate variations, consult Siemens Storage Recommendations ANIM-03114. Storage maintenance is to be documented for warranty information.
Installation Motor Dimensions For motors built in the frame sizes covered by this manual, the letter dimensions have the same definitions established Established dimensions for these frames may be found on catalog sheets or certified drawings. CAUTION Damp Location. Can cause property damage if equipment is operated intermittently.
Installation Angular Alignment Hold each shaft at maximum end float. Rotate both shafts together, and measure between matching points at the outside diameter of the coupling faces for the top, bottom and both sides. because of possible axial shaft movement. difference of variation between them.
Installation Check for vertical alignment (parallelism) of coupled drive as follows: 1. Operate unit until normal temperature is reached (may require several hours). 2. Shut down motor and lock out switch. 3. Mount dial indicator as in Figure 2. 4. Rotate shaft, noting readings at 0°, 90°, 180°, and 270°...

Operation Trouble Shooting Between regular maintenance inspections, be alert for signs of motor trouble. symptoms are listed in the following table. Correct any trouble immediately and AVOID COSTLY REPAIR AND SHUT DOWN. TROUBLE Motor will not start. Usually line trouble. Single phasing at starter.
Operation Trouble Shooting TROUBLE Motor overheating Open stator windings. (continued…) Air Recirculation. Over voltage/under voltage. Ground. Improper electrical connections. Heat exchanger tubes blocked. Loose heat exchanger tubes. Fine dust under coupling Misalignment. having rubber buffers or pins. Bearing overheating. Oil level too high or low (sleeve bearing). Misalignment.

The following conditions will be found when accessing the motor interior; 1. 500 frame motors have air deflectors that are retained in the fit between the bearing housing and the stator yoke. Such air deflectors will be...
Water and detergents with an oven drying cycle may be used as an alternate on MICLAD™ VPI insulation systems. MICLAD™ is a Siemens trademark. High Voltage. May damage semi-conductors, small transformers, voltage regulators, and other devices.
Insulation Resistance Check insulation resistance periodically. Use a hand cranked or solid state insulation resistance tester and test with at least 500 volts, but not greater than motor rated voltage. For motors with newer insulation systems such as MICLAD™ VPI, the insulation resistance after one minute should be greater than 1000 megohms.
Maintenance When this method is used on the stator, the stator phases may be connected in series or in parallel to suit the available power supply if both ends of all phases are accessible. If only three leads are brought out of the motor, the current may be circulated between one terminal and the other two connected together.
Maintenance Insulated Bearings One or both bearings may be insulated to prevent shaft currents from pitting bearing surfaces. The insulation is located at the joint between the bearing housing or bracket and the bearing. Insulated bearings are designated by an instruction plate on the bearing housing.
The oil seals should be centered radially on the shaft and set so that the radial clearance is uniform on all sides. The 500, 580 and 1120 frames use self-centering oil seals that can accommodate small radial movements in the shaft. These floating labyrinth seals should be free to move radially in the bearing housing.
There should be no gap when mating surfaces are together. 3a. For 500, 580, and 1120 frames, apply a small bead of silicone RTV at the bearing housing parting surfaces. Loctite 518 may be used in replace of RTV in environments where silicon is prohibited.
Diametrical sleeve bearing clearances for the 500, 580, 680, and 800 frame motors are approximately 2 mils per inch of bearing diameter. Diametrical sleeve bearing clearances for the 1120 frame is in the range of 1.5mils per inch of...
Maintenance Bearing Replacement Antifriction Bearings For typical antifriction bearing configuration, see Figure 3. Replacement bearings manufacturer but must be equal to the originals used in the motor. When ordering bearings specify as follows: 1. The complete A.F.B.M.A. (Anti-Friction Bearing Manufacturers’ Association) bearing number from the motor nameplate.
1. Check replacement bearings for nicks or shipping damage. Do not scrape. 2. Remove the upper half of the bearing bracket. NOTE: For 500 frame, WPII motors, the upper top enclosure must be removed before disassembly of the upper bearing bracket.
Control of rotor end float in sleeve bearing motors is maintained in the drive end bearing. The total end float is 0.5 inch. On the 500, 580, 680 and 800 frames, the bearings are located axially by shims between the bearing bushing and the bearing capsule shoulders .
