Protect the Stator Core. Reduce Preparation Time. Make Rewinding More Profitable.
The Problem with Traditional Winding Removal
Most rewinding shops use conventional burn-out ovens or open fire to remove old windings. This method is common, but it creates several problems for modern repair businesses.The entire stator is exposed to high heat, The process can take several hours, Additional cooling time is required, Manual cleaning can be labor-intensive, Energy consumption can be high. Smoke, residue, and contamination affect the shop environment, Results depend heavily on technician experience and oven control, The laminated stator core may be exposed to unnecessary thermal stress that reduces its efficiency.For the customer, the biggest concern is simple: if the stator core is damaged during the repair process, the motor will lose efficiency after rewinding.
That is why the winding removal method matters.
The Key Advantage of our technology: Designed to Protect the Stator Core
If the insulation between laminations is damaged by excessive heat, the motor will experience higher core losses, increased operating temperature, reduced efficiency, and shorter service life. Our controlled induction heating technology is designed to exclude this risk.
Instead of heating the entire stator in a large oven, the system applies energy in a more targeted and controlled way. The objective is to loosen winding-retaining materials without unnecessary thermal exposure to the whole core.
This gives motor rewinding companies a powerful selling point:
You are not just rewinding the motor, You preserve its efficiency and reliability.
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
Many industrial customers compare rewinding with replacement.
- They want to know whether the repaired motor will be reliable, efficient, and worth the investment. This technology helps your shop answer that question with confidence.
- Instead of presenting rewinding as an old repair method, you can present it as a controlled remanufacturing process.
- You can explain that your shop uses advanced induction heating to remove windings more carefully, reduce unnecessary thermal stress, and help protect the motor’s original core efficiency.
- That message is powerful because it speaks directly to what customers care about: Lower downtime, Reliable repair quality, Preserved motor performance, Reduced waste, Better sustainability and Long-term equipment value
