Precision Econowind Products
Custom Electrical Coils
Coils may be single or multilayer, wet wound with adhesive or dry wound,
and freestanding or wound on a bobbin.
Custom Electrical Coils
Our reputation for quality and performance in the electrical coil market has made Precision Econowind LLC an industry leader in custom electric coil manufacturing.
Precision layered coils can be produced in a variety of round, rectangular, or custom shapes. Coils may be single or multilayer, wet wound with adhesive or dry wound, and freestanding or wound on a bobbin. Round wire or flattened wire can be used depending on space and cost requirements. These options allow for endless configurations to fit any application.
We use magnet wire made of copper, aluminum, or copper clad aluminum. Copper wire is typically used for its premium conductive properties. Aluminum wire can be substituted for weight-sensitive applications, or copper clad aluminum (CCA) wire can be used to reduce mass while retaining copper’s ease of soldering. Our proprietary high-temperature adhesive formulation allows coils to withstand temperatures upwards of 500 °F. This allows customers to place coils in tight spaces where ventilation is limited.

Additional Time Required for Tooling
We work with inner diameters from 0.062” to 10.0” and wire gauges from #16 AWG to as small as #48 AWG. Inner diameter tolerances can be held to as tight as ±0.001” for smaller coils and ±0.003” for larger coils. Value added processes, such as stripping and tinning of the lead wires and end connector assembly, are available to create complete coils ready for installation. Electrical testing including resistance, inductance, and turns count testing can be performed to customer specifications. The typical lead time for a custom coil is 3 weeks, with additional time considerations required for specialized tooling. As a service to customers, we accept blanket orders and can maintain stock on customer items. For more information about our custom electrical coils, see the table below, or contact us directly.
