Y2 Three Phase Asynchronous Motor Series

Key Features & Advantages

1. High Efficiency & Energy Saving: Designed with optimized electromagnetic materials and construction to minimize losses, resulting in higher operational efficiency. This translates to lower electricity consumption and reduced operating costs over the motor’s lifespan.
2. High Starting Torque: Provides robust starting performance, enabling reliable startup even under full load conditions, which is critical for driving pumps, compressors, and other equipment with high breakaway torque requirements.
3. Low Noise & Vibration: Features precision-balanced rotors and high-quality bearings, ensuring smooth, quiet, and low-vibration operation. This enhances operational comfort and reduces wear on connected equipment.
4. Excellent Insulation & Thermal Protection: Utilizes Class F (or higher) insulation systems, allowing for a higher temperature rise margin and increased service life under demanding conditions. Many models include built-in thermal overload protectors (PTC thermistors or thermostats) to prevent burnout from overcurrent or overheating.
5. Robust Construction & Protection: Housed in a cast iron frame (for larger models) or aluminum alloy frame (for smaller models) with a high degree of ingress protection (typically IP55 for total dust protection and protection against water jets). This ensures reliable operation in harsh, dusty, or humid environments.
6. Wide Voltage Compatibility: Designed for stable three-phase operation. Similar to DONGTAO’s pump technology, these motors are engineered for reliable performance within a specified voltage range (e.g., 330V-380V as indicated for pump applications), accommodating common grid variations.

Standard Specifications & Model Framework

(Note: While the provided product sample PDF lists pumps driven by these motors, a standalone detailed parameter table for the Y2 motor series itself is not extracted. The following is based on the industry-standard Y2 series specifications.)

Motor models typically follow a coding system that details its key attributes (e.g., Y2-100L1-4). Key specifications include:

• Output Power: Ranges from 0.12 kW (fractional HP) to over 315 kW, covering the full power needs of DONGTAO’s pump lineup and other machinery.
• Voltage & Frequency: Standard three-phase, 380V, 50Hz (common for target markets). Other voltages (e.g., 415V, 220V/440V dual voltage) are available.
• Number of Poles & Speed: Available in 2-pole (~2900 RPM), 4-pole (~1450 RPM), 6-pole (~960 RPM), etc., to match the required driven speed of the equipment (e.g., high-speed vs. standard-speed pumps).
• Efficiency Class: Meets or exceeds IE1 (Standard Efficiency) or IE2 (High Efficiency) levels as per IEC 60034-30 standards.
• Mounting: Standardized foot mounting (IM B3, IM B35) or flange mounting (IM B5, IM B14) per IEC standards for universal compatibility.
• Insulation Class: Class F (155°C), with a temperature rise limited to Class B (80K) or lower for enhanced reliability.
• Protection Degree: Common enclosure is IP55, offering robust protection against dust and water jets.
• Duty Cycle: Designed for continuous duty (S1).
• Cooling Method: Totally Enclosed Fan-Cooled (TEFC).

Applications

• Primary Drive for Pumps: The designated power unit for all DONGTAO three-phase submersible pumps, sewage pumps, pipeline pumps, and self-priming pumps.
• Industrial fans, blowers, and compressors.
• Conveyor systems, mixers, and crushers.
• Machine tools, lathes, and other factory automation equipment.
• Agricultural processing machinery.
