Windings electric motor solution for wireline tooling hydraulic pump applications provides 5kW of power at 8,000RPM while operating continuously at 200°C ambient temperature. Efficiency is over 90% higher than traditional induction motors, almost doubling the productive working time. And at 3-1/8” in diameter and 11” long, the overall tool string package length can be reduced by up to 2/3. Relative to a typical induction motor solution, the Windings permanent magnet motor provides:

  • 50% reduction in motor package size

  • Over 90% increase in efficiency


A design study conducted by Windings’ engineers revealed that induction motor topology is not capable of meeting the needs of wireline service companies for higher power density and high efficiency over the entire operating envelope. Because permanent magnet-based rotors do not require induction of a magnetic field, motors based on this topology have efficiencies greater than 90% over a wide speed and torque range and offer up to twice the power density of a comparable induction-based motor design.

Windings is 100% focused on providing custom electric motor solutions that are optimized, tested, and manufactured to client-specific application requirements. Our engineering team is comprised of design and manufacturing engineers having extensive experience in engineering magnetic rotor assemblies, wound stators, and complete motor assemblies. From performance and manufacturability optimization of existing designs to a complete engineering package from concept to production, Windings engineers have you covered.

One of the things that makes Windings unique is our stance on ownership of intellectual property. Unlike most motor manufacturers, Windings offers our clients the option to retain ownership of any unique intellectual property developed during the project, offering maximum flexibility for clients over the life of the product.

Windings has earned a strong reputation as a trusted partner by consistently delivering high-quality products and services that are optimized for the requirements of each application. To ensure the stringent requirements of the Oil & Gas industry are met consistently, Windings’ Quality Management System (QMS) Certifications include ISO9 001:2015 / AS9100-D, ITAR Registration, and NADCAP Accreditation. In addition, Windings’ employs J-STD-001 Application Specialists and a J-STD-001 Certified Instructor to ensure the highest quality soldering operations.
