SDN/SDNZ Series General-purpose High-Voltage Synchronous Motors

Product Overview:
The SDN/SDNZ series high-voltage synchronous motors are heavy-duty drive solutions engineered for demanding industrial applications. Designed for continuous operation in metallurgy, mining, petrochemical, building materials, and power generation industries, these motors feature a robust welded steel frame construction that ensures structural integrity and long-term reliability under harsh operating conditions.
With a power range spanning 400 kW to 3150 kW and support for both 6 kV and 10 kV voltage levels, the SDN / SDNZ series offers wide coverage for large-scale mechanical drive systems. Custom configurations are available for special ambient temperature ranges and high-altitude installations, making the series adaptable to a broad range of project environments.
Key Features:
Wide Power Range: Covers 400 kW to 3150 kW, suitable for a variety of large-scale industrial drive applications with continuous-duty (S1) operation.
Multiple Protection Levels: Available in IP00, IP11, and IP43 enclosure ratings to suit varying environmental conditions including dust, moisture, and corrosive atmospheres.
Flexible Mounting Options: Supports horizontal and vertical mounting arrangements (IM7211, IM7311, IM7312, IM7621, and others) for easy integration into diverse plant layouts.
High Insulation Reliability: Insulation class F or above ensures excellent thermal endurance and electrical reliability, extending the motor's service life.
Efficient Cooling: IC01 and IC37 cooling methods provide effective heat dissipation during high-load, long-duration operation.
Customization Available: Ambient temperature tolerance and altitude compensation can be specified to meet requirements in extreme climates or high-altitude regions.
Typical Applications:
The SDN/SDNZ series is widely used across heavy industries. In metallurgy and mining, it drives ball mills, compressors, and crushers. In the petrochemical sector, it powers pumps, compressors, and agitators. For building materials and cement production, it is applied to rotary kilns, raw material mills, and vertical mills. In power generation, typical applications include feed water pumps, induced draft fans, and blowers.
