2. Product Description and Application

The document covers AC/DC elevator hoist motors with standard reconnectable series fields, ball bearing construction, and a temperature rise of 50ºC. These motors are designed for continuous duty in elevator service, operating at 1800 RPM with open construction.

DC generator data is also provided, indicating compatibility with the hoist motors for elevator applications.

3. Electrical Specifications

The data tables include key electrical parameters for various motor and generator configurations, including:

• Voltage: 200V, 230V, 460V, 575V (3-phase, 60Hz)
• Current Ratings: No-load (N.L.) amps, Full-load (F.L.) amps, Locked rotor (L.R.) amps
• Power Ratings: Kilowatt (KW) and horsepower (HP) equivalents
• KVA Codes: Identification codes for transformer sizing and motor protection
• Frame Sizes: Various frame designations such as 286A/280T, 324A/320T, 409A/360T, etc.

4. Performance Curves and Parameters

The document references HPCurve codes (e.g., S11714) which likely correspond to performance or torque-speed curves for the motors. These curves assist in selecting the appropriate motor for specific elevator load requirements.

5. Usage Recommendations and Notes

• Motors are suitable for continuous duty elevator service with open construction and ball bearings.
• Standard reconnectable series fields allow flexibility in motor wiring for different voltage applications.
• Temperature rise is limited to 50ºC to ensure motor longevity and reliability.
• Consult factory for certain high-power or special configurations (e.g., 50 HP and above).

6. Data Summary Highlights

Sample data points extracted from the tables:

• At 200V, 3-phase, 60Hz:
  - 18.7 A no-load, 37.0 A full-load, 280 locked rotor amps, KVA code J, frame 84 A
• At 460V, 3-phase, 60Hz:
  - 8.1 A no-load, 16.2 A full-load, 122 locked rotor amps, KVA code J, frame 36 A
• At 575V, 3-phase, 60Hz:
  - 6.4 A no-load, 12.9 A full-load, 96 locked rotor amps, KVA code J, frame 29 A
• Higher power ratings show increased current and KVA codes, with frame sizes scaling accordingly.

7. Document Format and Presentation

The document includes multiple tables listing electrical parameters for various motor sizes and voltages. It also contains references to performance curves and frame sizes. Contact information is repeated for ease of reference.

Critical Information and Best Practices

• Ensure motor selection matches voltage and current requirements for the elevator application.
• Use KVA codes for proper transformer and protection device sizing.
• Adhere to continuous duty ratings and temperature rise limits to maintain motor reliability.
• Consult the factory for configurations beyond standard catalog data.
