Product catalog summary

Overview: The document outlines the technical specifications and features of ALXION's STK Permanent Magnet Frameless Alternators, designed for direct drive applications in wind turbines. These alternators are recognized for their high power-to-weight ratio and cost-effectiveness, eliminating the need for gears.

Main Specifications:

Rated power ranges from 200 W to 99 kW, depending on size and speed.
Rated speeds range from 80 RPM to 1500 RPM.
Available in six diameters from 145 mm to 795 mm, with internal diameters from 56 mm to 630 mm.
Various voltage options up to 500 Vac.

Key Features:

No maintenance required due to the absence of gears.
High efficiency and simplified mechanical integration.
Optimized for cost and mechanical design.

Applications: Suitable for low to medium power wind turbines, these alternators provide power for remote locations such as lighthouses and isolated plants, offering a more compact and efficient solution compared to traditional generators.

Technical Characteristics:

145 STK Alternators: Detailed specifications include phase resistance, inductance, and rotor inertia.
190 STK Alternators: Emphasis on rated power, current, and voltage at rated speed.
300 STK Alternators: Specifications include rated power, current, and phase resistance.
400 STK Alternators: Includes rated speed, power, and phase resistance, with integration instructions.

Integration Guidelines: Detailed instructions for mechanical integration include alignment tolerances, cable specifications, and thermal management considerations. A full integration handbook is available upon request.

Conclusion: ALXION's STK alternators provide a robust solution for wind turbine applications, emphasizing high efficiency, low maintenance, and cost-effectiveness. Precise integration is crucial for maximizing performance and reliability.

Technical Specifications: Detailed specifications for 400 STK, 500 STK, and 800 STK alternators are provided, designed for specific operational conditions with a unitary power factor and a single voltage of 230Vac phase to phase.

Integration and Installation: Cables are made of PU, class 6, suitable for cable-bearing chains. Alignment of rotor and housing must be within specified tolerances, with optional tools available for precise assembly. Thermal device cables and positioning guidelines are provided.

General Recommendations: Ensure perfect contact between housing and user's bore to avoid thermal problems. Use specified centering diameters for housing mounting. Consult ALXION for execution tolerances and specific requests.
