Paper Mill Motor Repair Services
IPS offers single-source pulp & paper mill repair services for AC & DC motors, including reliability maintenance and reliability engineering, for pulp and paper mills, lumber mills and plywood plants, combining in-shop repair services, field services and new product sales.
IPS repair services include complete rebuilds on refiners, refiner drive motors and vacuum pump motors. We recommend EnduraSeal™ VPI rewinds for motors operating in wet conditions, including exposure to moisture, steam and chemicals (EnduraSeal™ rewinds are backed by a five-year warranty).
With more utilities incentivizing repairs with upgrades, such as the Green Motor Initiative (GMI), pulp & paper operations can benefit by using “green rewinds” that qualify for incentives when rewound to their original nominal efficiency values. The VPI technology, materials and craftsmanship that go into EnduraSeal™ combine for dramatic, documented improvement — we can rewind a 5000HP refiner motor and uprate it to 5620HP, for more power in the same footprint, which means that motor can produce more product for a lower cost.
IPS technicians also offer a unique connection design for better cooling and easier cleaning. Lead maintenance is much faster and we can do it on-site with no need for motor changeouts, so for convenient scheduling and to schedule and less downtime.

Equipment repair, rewind and remanufacture
IPS offers service and repairs for AC & DC motors and generators, including turbine generators, refiner, chipper and bridle roll motors. Our regional service centers give us coast-to-coast coverage, while allowing us to respond quickly with more technicians and resources for emergency outages and short lead times.
In-house coil manufacturing gives us complete control of quality and delivery. IPS offers EnduraSeal® medium-voltage VPI up to 6.6 kV, MegaSeal™ high-voltage VPI up to 15 kV, and IntegraSeal™ fully cured B-stage hard coils up to 15 kV. We have extensive in-shop experience with large-scale projects, plus the lifting capacity and equipment to handle big jobs. We also offer complete machining services and replacement spare parts.
Remanufacturing for old motors
If you have older, non-standard frame motors that are no longer available from the OEM, we can help with retrofitting. We perform Fit-Form-Function assessments on these units, take measures and pictures duplicate all critical dimensions, and then reverse engineer to build drop-in replacement motors. Given advances in materials and craftsmanship, we can usually improve power density, reliability and efficiency too — without OEM involvement and despite the absence of drawings.
Our Field Services combine predictive and preventive services, to help your plant move from a reactive, repair-focused stance to a managed program designed for improved reliability and uptime.
Predictive and preventive maintenance services
IPS predictive services include vibration and modal analysis on motors, blowers and fans, motor efficiency testing, Doble and Partial Discharge testing, thermography and ultrasonic testing. We offer dye penetrant testing to check fan wheels for cracks and pre-warranty expiration inspections and consults on all motors and mechanical components. IPS preventive services include cryogenic, dry ice cleaning for blowers and fans, dynamic balancing and precision laser alignment and lubrication programs.
Our reliability services also include supplemental maintenance, including emergency and outage support, and engineering services, including installed base evaluations and application/design solutions.
New product sales
As part of our single-source commitment to delivering reliability, we back our repair and field services with new product sales. We can make replacement recommendations or provide the OEM equipment you specify. As a Master Distributor for key OEMs, we can provide the right replacement unit for your requirements.
We can also bundle sales with equipment removal and installation. To learn more about our new product sales or paper & wood power services, talk to your regional IPS sales representative or contact us.
