    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.

  • Page 17: Insulation Resistance

    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.

  • Page 18: Bearings

    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.
  • Page 19 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.
  • Page 20 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.

  • Page 21: Bearing Lubrication

    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.
  • Page 22 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...

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.
  • Page 24 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.
  • Page 25 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 .
