Endeavor Technologies is the authority on rewinding Siemens synchronous and asynchronous built-in motor stators such as the 1FE1084-4WZ91-4ZW9.
Rewinding Specialists
Windings for machine tools require special consideration, especially water-cooled motorized spindles, servo motors, and torque motors. Our winding department is specifically geared to offer high level technical support and motor rewinding services for machine tool builders, spindle rebuilders, and end users.
You can be certain that your failed Siemens motor stator will perform and last like new because:
- Our Epox-E-Pak molding process is the perfect substitute for Siemen’s “casting” insulation ensuring that the winding will not only be protected against liquid contamination but will also have the necessary thermal conductivity for proper cooling.
- We install all new thermal protectors in every rewound stator. We stock all types including the KTY probes used by Siemens for many years which they now consider obsolete.
- Windings are painstakingly reverse engineered and carefully crafted to duplicate the original.
- Each rewound stator is exhaustively tested. Testing with a sophisticated winding analyzer verifies the integrity of the insulation system. But we also ensure that resistance, inductance, phase relationship, and more all meet the factory specifications so that the motor will perform as expected with the original drive parameters.
Additional Services
Many Siemens built-in motors are provided with an aluminum water jacket which can degrade when exposed to water-based refrigerant. If your cooling jacket has corroded, we can reverse engineer it and supply a replacement.
We’ll be happy to remove, re-install, and pressure test the stator in the headstock casting so that you can assemble your spindle with confidence that it won’t leak.
If you need assistance testing your reassembled motor or spindle, we have that capability with our Siemens run-off stand.
Choose Wisely
If your Siemens built-in motor winding has failed, trust the specialists–Endeavor Technologies. We’re standing by to rewind your Siemens motor 1FE1084-4WZ91-4ZW9 and get your machine up and running.
