Large Industrial Electric Motor Repair

Time is money! This statement especially holds true when it comes to large electric motor repair. With over 35 years in the electrical apparatus service industry, Laser Technologies understands that quick turnaround is often the difference between winning or losing an order. We offer same day to 24 hour quote turnarounds, expedited reverse engineering services, and 24/7 operating capacity to deliver laminations quickly. All electric motor repair orders take priority in our schedule to deliver on-time or before your promised dock date. Special expedited services are also available when requested.

In addition to quick turnaround, Laser Technologies understands the importance of getting it right when it comes to the integrity and quality of what goes back into your customer's motor. Quick delivery means nothing if the product does not conform 100% to your assembly requirements. Order processing, manufacturing, and quality procedures are in place and certified annually per ISO 9001:2015 standards to assure traceability and compliance are adhered to on every order. Special attention is given to the accuracy and consistency of our laminations geometry. Our goal is to deliver the highest quality product to your door to allow efficiency and time savings in the rewind process. Whether you are looking for loose laminations and vent plates to stack yourself, or you prefer to receive fully assembled stator cores, rotor cores or pole lamination assemblies, consider Laser Technologies to be your manufacturing partner of choice.

Why Do Motors Fail?

Certain components of motors degrade with time and operating stress. Electrical insulation weakens over time with exposure to voltage unbalance, over and under-voltage, voltage disturbances, and temperature. Extreme temperatures (hot or cold) are one of the most common risk factors in the life of an electric motor. Other factors that can lead to motor failure can include transient voltage surges or spikes, vibration, harmonic distortion, motor overload, misalignment, moisture and bearing current.

Lamination/Core Iron Damage

If it is determined that the laminations of the stator and/or rotor are damaged, an analysis should be performed to compare the cost of repairing the existing electric motor versus the cost of replacing it with a new electric motor. Understanding the lead times of electric motor repair versus buying new is also a key factor when making a decision.

Getting a Quote for New Laminations and/or Re-stacking

At Laser Technologies, we make our quoting process for new laminations as easy and quick as possible. Filling out one of our data forms with rough dimensions is really all we need. The key dimensions we look for include the outside diameter, inside diameter, width & depth of the slots, and number of slots. We understand these dimensions at time of quote may not be 100% accurate, and that is ok. We typically have quotes turned around within 24-48 hours.

Laser Technologies is your source for complete turnkey reverse engineering and re-stacking of stator cores, rotor cores, armature cores and DC poles. For over 35 years, we have added unique value through a wide range of in-house services and state-of-the-art equipment that enable us to deliver fast turnaround to your exact specifications. Our unparalleled commitment to quality, process control and engineering results in a superior product - precisely aligned.

Electric Motor Repair Process

Every new electric motor job begins with a detailed inspection. The motor is disassembled and the core is removed. Laminations are separated and detailed measurements are taken so that a new replacement lamination can be reverse engineered and prepped for manufacturing. We then laser cut all the new laminations, apply any coatings that may be required, then reassemble and weld the core. The stack is then reinserted into the motor housing, inspected, validated and then prepped for rewinding. The entire process can take anywhere from a few days to several weeks depending on the complexity of the job, the extent of the damage and the urgency of the customer's situation.
