Stator Coil Manufacturers, Suppliers, Exporters in Pune, Maharashtra

Suniti Electricals is one of the trusted Stator Coil Manufacturers in Pune, Maharashtra. Suppliers, and Exporters in Pune, Maharashtra, known for producing high-quality stator coils for modern electric motors and generators. With years of expertise in the electrical manufacturing industry, we design precision-engineered coils that meet the evolving demands of various applications. Our products are crafted using advanced winding technology, superior insulation materials, and premium-grade copper conductors to ensure long-lasting performance. By continually upgrading our production processes for better efficiency and automation, our stator coils remain a preferred choice in both domestic and international markets.

Types of our Stator Coil

With the status of a top-notch Stator Coil manufacturer in Pune, Maharashtra, we are providing the best quality Stator Coil like:

  • Concentrated Winding

    We produce concentrated winding stators where a coil is wound around a single stator tooth to create a complete magnetic pole. Our design becomes compact, efficient, and economical because of this. With end-turn lengths minimized, our concentrated windings conserve copper usage, loss reduction, and provide superior performance for simplicity demanding applications and maximum efficiency utilization.

  • Distributed Winding

    Our distributed winding technology is founded on spreading the coils over many adjacent stator slots rather than stacking them onto a single tooth. This technique produces a smoother magnetic field, with consequences of smoother flux and near-sinusoidal EMF. Through minimizing harmonics, our distributed windings promote quieter operation, higher efficiency, and constant torque output—features highly sought in mission-critical industrial and automotive applications.

  • Hairpin Winding

    We also specialize in complex hairpin winding configurations with flat, rectangular copper conductors with "hairpin" forms precisely placed into stator slots and welded by high-quality welding. This new approach helps us attain a larger copper fill factor and thus low electric resistance, improved current-carrying capacity, and thermal efficiency. Our hairpin windings are suitable for future electric motors requiring high efficiency, ruggedness, and high-quality power density.

Features of our Stator Coils

Being one of Pune, Maharashtra's leading Stator Coil suppliers, all our varieties of Stator Coil are supplemented with advanced technology equations including:

  • High-Temperature Conductors – We employ high-quality copper and aluminium conductors in order to manufacture our stator coils. These conductors undergo the most up-to-date enamel coatings, which provide thermal conductivity and electrical breakdown resistance. What this means is that coils can sustain high current loads without compromising on performance. With automated conductor shape and size systems, we provide quality consistency in every batch. We also apply multi-layer conductor designs with reduced losses and optimised efficiency of energy-saving motors for the new millennium.
  • Precision Winding and Insulation – We maintain CNC-winding machine gears and automatic tension control system instruments in our factory to facilitate faultless wire mounting. This precision encourages magnetic field strength and smooth motor operation. We apply multi-layer electrical insulation systems that significantly increase electrical strength and ruggedness. For added reliability, we employ heat-resistant tapes and special resin formulations which can withstand harsh industrial environments. All of these technologies combined ensure that our coils provide stable and reliable performance throughout their life.
  • Vacuum Pressure Impregnation (VPI) – We apply VPI technology to all the coils in order to provide maximum bonding and water tightness. In the process, coils are vacuum-impregnated with special grade resin, which fills micro-sizes of porosity as well and provides extra mechanical strength. The process makes the coil strong against heat expansion, vibration, and environmental stress, and thus it is fit for mission-critical applications. With the use of computer-controlled VPI chambers and automated curing units, we get even resin saturation in all coils, resulting in improved operational safety and life.
  • Thermal Class Ratings – Our stator coils have Class H and above thermal class ratings, with which they can withstand high-temperature use without failure through insulation. Our coating and material are very heat-resistant, as well as high-tech materials to allow motors to continue functioning properly when subjected to heat stress. This allows our coils to be suitable for long-duration high-load applications in power plants and renewable systems. We also perform accelerated thermal aging tests to validate long-term reliability of such coils by their life testing.
