This document provides detailed technical specifications for AC dry hydraulic elevator pump motors manufactured by Imperial Electric. The motors are squirrel cage induction type, dripproof, with ball bearings and Class B insulation, designed for 40ºC ambient temperature, 3-phase, 60 Hz operation. They utilize a WYE start and Delta run configuration.

1. Motor Specifications

The motors are categorized by frame size and horsepower (HP), with corresponding electrical and mechanical parameters listed for various voltage ratings (200 V, 230/460 V, and 575 V). Key parameters include:

• Full Load Amps (FLA): Current drawn at full load for each voltage.
• No Load Amps: Current drawn when the motor is running without load.
• Locked Rotor Amps (LRA): Current drawn when the rotor is locked, indicating starting current.
• KVA Code: Code letter indicating locked rotor KVA per horsepower, used for sizing electrical components.
• Elevator Duty BTU per Hour: Heat dissipation rating relevant to elevator duty cycles.
• RPM: Motor speed at full load.

Frame sizes range from 215T to 365T, with horsepower ratings from approximately 15 HP up to 91 HP. The motors support high start frequencies, with versions rated for 80 starts per hour and 120 starts per hour, suitable for elevator applications requiring frequent starts.

2. Electrical Characteristics

The motors operate at standard industrial voltages with dual voltage ratings (230/460 V) and single voltage options (200 V and 575 V). The current ratings decrease with increasing voltage, as expected. Locked rotor amps are significantly higher than full load amps, reflecting the high starting current typical of squirrel cage induction motors.

3. Thermal and Mechanical Considerations

The motors are designed for dripproof environments and include ball bearings for durability. Class B insulation ensures thermal protection up to 130ºC. The heat dissipation values (BTU per hour) are provided to assist in thermal management within elevator machine rooms.

4. Application and Usage

These motors are specifically designed for hydraulic elevator pump applications, where frequent starts and stops are common. The WYE start and Delta run configuration helps reduce starting current and mechanical stress.

5. Summary Tables

The document contains comprehensive tabulated data listing motor frame, voltage, amperage (full load, no load, locked rotor), KVA code, horsepower, RPM, and heat dissipation. These tables enable engineers to select appropriate motors based on load requirements, voltage availability, and start frequency.

Critical Information and Best Practices

• Ensure motor selection matches the required start frequency (80 or 120 starts per hour) to avoid overheating.
• Verify voltage compatibility and corresponding current ratings for proper electrical supply sizing.
• Consider heat dissipation ratings for adequate ventilation and cooling in elevator machine rooms.
• Use the KVA code for correct sizing of motor starters and protective devices.
• Maintain ambient temperature within 40ºC to ensure motor insulation longevity.

Overall, this document serves as a technical reference for specifying and selecting Imperial Electric's hydraulic elevator pump motors, ensuring reliable and efficient elevator operation.
