With its state of the art facilities unfold across metropolis, Tumkur & Hubli.
Rajamane offers entire electric motor repair, rebuild, renew services, AC Motors services From standards to personalized. Rewinding of all genre of AC induction motors from FHP to 5000HP, voltage up to 13.8KV. Come by winding to fashioned coils each for stator coil and rotor.

Electric motor failures are often caused by “in-operation” factors, such as production activities and the factory environment in which they operate. Other failures are due to “off-line” factors, including inadequate or substandard motor repair practices, and improper motor shipping, storage, and installation. Compared with in-operation failures, those caused by off-line factors are much easier to eradicate — and represent an overlooked opportunity to improve electric motor reliability.

To capitalize on this chance, your company should evaluate and work with electric motor rebuilders based on their adherence to high-quality repair standards and practices. It's important to remember that the expertise, professionalism, and overall quality offered by electric motor repair companies can vary significantly from shop to shop — and also over time. Regardless of volume or location, however, expert repair shops share many of the same characteristics. When choosing a provider, look for the following traits:
  • Maintains clean, orderly work areas and has a stable workforce of well-trained, technically proficient employees.
  • Is fully equipped with state-of-the-art test equipment and instruments. Expert shops will calibrate their instruments annually to National Institute of Standards and Technology (or equivalent) standards to ensure the accuracy of repair readings and measurements.
  • Adheres to a documented set of repair procedures. High-quality motor shops are procedure driven and never rely solely on the skills and experience of shop technicians. These providers have developed detailed procedures covering electric motor repairs and file each step of the repair process. This helps ensure your motors are repaired or rebuilt to documented mechanical and electrical standards every time, regardless of when repairs are made or who made them.
  • Use high-quality replacement components procured through transparent supply channels. This alleviates customer concerns about obsolete or counterfeit components that may result in poor motor performance.

Among other actions, the procedures followed by high-quality shops include conducting a stator core test before and after winding removal, as well as confirming that the core has not been damaged during the repair process. Core loss testing and “hot-spot” testing are vital when it comes to determining the condition of the AC induction motor stator iron integrity. Operational expenses and long-term stator winding reliability are the primary considerations. Core losses decrease the efficiency of electric motors and can increase a plant's utility costs.
