Our winding process saves you money

Every step of our winding process is carefully engineered to ensure that your motor is returned to factory specification as quickly as possible. Our process avoids the delays and potential damage of traditional repair techniques, allowing a faster turnaround. Our highly skilled technicians apply the most rigorous standards to ensure that your valuable equipment will enjoy the longest possible service life. We also offer options like Epox-E-Pak to protect your servomotor or spindle motor investment better than the original construction, insuring the maximum ROI on your valuable equipment. Please keep reading for more details.

Winding technical overview

Shortcuts in the rewind process mean that the customer gets short-changed on materials in order to cut costs, or on quality control steps to reduce winding time. Too often the result is a premature failure.  Endeavor Technologies offers the highest quality workmanship combined with the highest quality materials.

Our process prevents core damage that may lead to costly downtime!It all begins with stripping or removing the failed winding. Our process of softening the existing varnish with moderate heat before pulling the coils mechanically is clearly superior to the "burnout" method favored by the motor repair industry. Exposing your stator core to the high temperatures of the burnout process risks damage to the insulation on the individual laminates. Proponents of this method often acknowledge the risk, but tell you that they test every core to ensure that resulting losses aren't excessive. Our method doesn't put your valuable equipment at risk in the first place! 
 
The core is inspected and any burrs or rough edges that could damage the enamel wire are carefully removed. Class H ground wall insulation is added. Slot liners are cuffed to provide that extra protection where the coils are most vulnerable. A computerized winding machine optimizes coil manufacturing, producing highly consistent coils designed with minimal risk of failing turn-to-turn. As the coils are installed, more class H insulation is added to protect against premature failure. After the coils are internally connected, specially imported class H lead wire is installed. Fanuc, Yaskawa, and Mitsubishi use this product because it combines a 200C temperature rating and and high flexibility with extraordinary resistance to chemical attack. There is nothing else like it in the market, and your motor will only be re-manufactured with it by Endeavor Technologies.
 
The completed winding is treated with a powerful epoxy varnish to protect it during service. Or better yet, completely molded into epoxy with our Epox-E-Pak process for the best protection and longest service life.

When your equipment is processed correctly no damage occurs
This is a correctly prepared stator core ready for rewinding

Lack of knowledge can lead to machine down time
This is a stator from the exact same motor type as the stator above, this one was "repaired" by another shop instead of carefully remanufactured.
