  • Page 6: Shipment

    U.S. ELECTRICAL MOTORS Shipment & INSTALLATION AND MAINTENANCE Handling SHIPMENT Prior to shipment, all Titan-II Motors undergo extensive electrical and mechanical testing, and are thoroughly inspected. Upon receipt of the motor, carefully inspect the unit for any signs of damage that may have occurred during shipment.

  • Page 7: Storage

    Storage U.S. ELECTRICAL MOTORS INSTALLATION AND MAINTENANCE III. STORAGE 1. When to put a Motor in Storage. If a motor is not put into immediate service (one month or less), or if it is taken out of service for a prolonged period, special storage precautions should be taken to prevent damage.
  • Page 8 Storage U.S. ELECTRICAL MOTORS INSTALLATION AND MAINTENANCE All motors must have the shaft rotated a few turns once a month to maintain a lubricant film on bearing races. 3. Periodic Maintenance/ Insulation History The only accurate way to evaluate the condition of the winding insulation is to maintain a history of the insulation readings.
  • Page 9 Storage U.S. ELECTRICAL MOTORS INSTALLATION AND MAINTENANCE Insulation resistance readings must not drop below the value indicated by the following formula: Rm = Kv + 1 Rm = minimum insulation, in megohms, at 40°C Kv = rated motor voltage in kilovolts Dielectric Absorption Ratio: In addition to the individual test reading, a dielectric absorption ratio may be required.

    Installation U.S. ELECTRICAL MOTORS Location & INSTALLATION AND MAINTENANCE Foundation INSTALLATION LOCATION When selecting a location for the motor and driven unit, keep the following items in mind: 1. The location should be clean, dry, well ventilated, properly drained, and provide accessibility for inspection, lubrication, and maintenance.

  • Page 11: Initial Installation

    Initial U.S. ELECTRICAL MOTORS Installation INSTALLATION AND MAINTENANCE INITIAL INSTALLATION 1. Coupling or Pulley Installation Remove the shaft locking device shipped on motor (as applicable). Wash protective coating from the motor shaft extension(s) with solvent. Install couplings or pulleys on motor shaft per manufacturers' recommended fit and mounting practices.

    Initial U.S. ELECTRICAL MOTORS INSTALLATION AND MAINTENANCE Installation B. Parallel Alignment (See Figure 3B) Fasten a dial indicator onto one coupling hub with the indicator button on the cylindrical surface of the opposite coupling hub. Rotate shafts together and take readings at four points, 90° apart. Relocate motor until total indicator movement in full rotation does not exceed .002".

    Initial U.S. ELECTRICAL MOTORS INSTALLATION AND MAINTENANCE Installation 5. Reversing Rotation The direction of rotation may be reversed by interchanging any two, of the three power phases to the motor leads. Be sure that the power is off and steps are taken to prevent accidental starting of the motor before attempting to change any electrical connections.
