Technical Data for YL Series Vertical High Voltage Three-Phase Asynchronous Motors (6kV IP23 and 10kV IP23)

1. Overview

This document provides detailed technical specifications and mounting dimensions for the YL series of vertical high voltage three-phase asynchronous motors, designed for 6kV and 10kV power supply systems with IP23 protection. The motors are categorized by rated power, speed, current, efficiency, power factor, locked rotor current and torque, maximum torque, and weight.

2. Technical Specifications

The motors are specified by model type, rated output power (kW), rated speed (r/min), rated current (A), efficiency (%), power factor (cosφ), locked rotor current (multiple of rated current), locked rotor torque (multiple of rated torque), maximum torque (multiple of rated torque), and weight (kg).

2.1 6kV IP23 Motors

• Rated power ranges from 220 kW to 3550 kW.
• Rated speeds available: 1480 r/min, 990 r/min, 740 r/min, 590 r/min, and 490 r/min depending on the model.
• Efficiency ranges from approximately 90.6% to 96.1%, increasing with motor size and power.
• Power factor varies between 0.73 and 0.89, generally increasing with power rating.
• Locked rotor current is typically 6.5 times rated current for 4-pole motors, decreasing slightly for motors with more poles.
• Locked rotor torque is about 0.6 to 0.8 times rated torque, and maximum torque is about 1.8 times rated torque across models.
• Weights range from approximately 1650 kg for smaller motors to over 10,000 kg for the largest models.

2.2 10kV IP23 Motors

• Rated power ranges from 220 kW to 3150 kW.
• Rated speeds include 1485 r/min, 980 r/min, 740 r/min, 590 r/min, and 490 r/min.
• Efficiency ranges from about 90.9% to 95.9%, slightly lower than 6kV models at comparable power.
• Power factor is generally between 0.72 and 0.89, depending on power and speed.
• Locked rotor current is higher than 6kV models, around 7.0 times rated current for 4-pole motors.
• Locked rotor torque and maximum torque values are consistent with 6kV models (0.6-0.8 and 1.8 times rated torque respectively).
• Weights range from approximately 2500 kg to nearly 10,000 kg depending on frame size and power.

3. Mounting and Overall Dimensions

Mounting dimensions are provided for both 6kV and 10kV motors, categorized by frame number and number of poles. Key dimensions include:

• Frame sizes: 355, 400, 450, 500, 560, and 630.
• Number of poles: 4, 6, 8, 10, and 12 depending on model.
• Dimensions such as N, P, M, D, E, F, G, T, LA, AC, AD, and L are listed in millimeters, defining mounting hole locations, shaft sizes, and overall motor length.

Note: The data is for user reference; in case of discrepancies, the original supplied documentation prevails.

4. Critical Parameters and Recommendations

• Efficiency and power factor improve with motor size and rated power; selecting the appropriate motor size is critical for energy efficiency.
• Locked rotor current and torque values indicate starting performance; these should be considered in system design to ensure compatibility with power supply and mechanical load.
• Weight and mounting dimensions must be accounted for in installation planning to ensure proper support and alignment.
• Different pole numbers correspond to different rated speeds, allowing selection based on application speed requirements.
• IP23 protection rating indicates suitability for environments with limited exposure to water and dust; additional protection may be required for harsher conditions.

5. Summary

The YL series vertical high voltage three-phase asynchronous motors offer a wide range of power ratings and speeds for industrial applications requiring 6kV or 10kV supply. The detailed technical data supports selection based on power, efficiency, starting characteristics, and installation requirements. Mounting dimensions facilitate integration into existing systems, with clear notes on data applicability.
