Protect the Stator Core. Reduce Preparation Time. Make Rewinding More Profitable.
Most rewinding shops use burn-out ovens or open-flame heating to remove old windings. Although common, this process can overheat the laminated stator core and damage the thin insulation between the core laminations. When this insulation is degraded, eddy-current losses increase, causing lower motor efficiency, higher operating temperature, and greater energy consumption after rewinding. That is why the winding removal method matters.
Economic Effect for Rewinding Shops (for example is used 45 kWt 2 pole stator)
Using the induction-based method, full stator cleaning is completed in approximately 12 minutes, with total electricity consumption of approximately 5 kWh, and approximately 12 minutes of operator labor.
Using a conventional burn-off oven method, the process requires approximately 4 hours of furnace heating at 50 kW, consuming approximately 200 kWh of electricity, followed by approximately 2-4 hours of manual cleaning by a skilled worker before the next rewinding steps can proceed.
Based our experience in using that technology for almost 10 years, the induction-based process will provide:
- 16x reduction in total cycle time to the next rewinding step; (12-15 min instead of 4-6 hours)
- 40x reduction in electricity consumption; (3-5 kWt instead of 100-200 kWt)
- 16x reduction in direct labor time; (12-15 min instead of 4-6 hours)
- Protects the Stator Core - The process is designed to reduce unnecessary thermal exposure and help preserve the laminated stator core during winding removal.
- Helps Maintain Motor Efficiency - By protecting the stator core, the technology supports the goal of delivering rewound motors that maintain strong performance and energy efficiency.
- Speeds Up Stator Preparation - Targeted heating can help loosen old winding materials faster and reduce preparation bottlenecks.
- Exclude Dependence on Burn-Out Ovens - The technology is a full replacement of conventional ovens or open fire.
- Improves Process Control - Defined heating parameters make the process more consistent, measurable, and repeatable.
- Creates Cleaner Working Conditions - A focused heating process is designed to reduce smoke, residue, and unnecessary contamination compared with traditional high-temperature preparation methods.
- Strengthens Your Sales Argument - You can tell customers that your shop uses a modern process designed to preserve the stator core, reduce unnecessary heat exposure, and support high-quality rewinding.
Why This Technology Helps You Sell More Rewinding Services
This technology gives rewinding shops a stronger sales message. You can explain to customers that your shop uses advanced controlled induction heating to remove old windings more carefully, reduce unnecessary thermal stress, and help protect the stator core.
The message is simple:
Your motor is not only rewound. Its efficiency, reliability, and long-term value are being protected.
This directly addresses what customers care about most: lower downtime, reliable repair quality, preserved motor performance, reduced waste, better sustainability, and longer equipment life.
