Your Trusted Partner for Electric Motor Repair Solutions
Founded in 1977, Demaria Electric has established itself as a leader in electric motor repair, serving critical industries like petroleum, maritime, and power generation. Our family-owned business began in a garage catering to the Los Angeles and Long Beach Harbors and has evolved into a world-class operation with decades of technical expertise. We employ an in-house Electrical Engineer and utilize EASA-certified programs to engineer specialized coil designs, ensuring optimal performance for demanding applications. Our VPI (Vacuum Pressure Impregnation) system uses Von Roll #74041 epoxy varnish, tested monthly for purity, to guarantee long-term insulation reliability. Advanced diagnostics include computerized core loss testing and vibration spectrum analysis using SKF Multilog IMx-S equipment, ensuring every motor meets rigorous API balancing specifications.With a full machine shop and NETA-certified technicians, we perform precision machining and adhere to the latest IEEE 522 and NETA standards for motor testing. Our commitment to quality is evident in every repair, from random/form coil rewinds to submersible pump motor restoration. Our open-door policy allows clients to observe testing and refurbishments, fostering transparency and trust. Our 24/7 emergency response team and four decades of experience make us the preferred partner for Southern California's industrial sector.

Electric Motor Repair
Our electric motor repair services cater to industrial clients across petroleum, maritime, and power generation sectors. We use EASA-certified software for coil redesign, ensuring optimal torque and horsepower. Each repair includes computerized core loss testing and vacuum pressure impregnation with Von Roll epoxy. Our API-certified technicians balance rotating equipment to 4W/N specifications, extending motor lifespan and preventing overheating.
Coil Rewinding
We specialize in precision coil rewinding for AC/DC motors and synchronous equipment. Our process includes random and form coil replacement using Nano Shield wire rated for high transient voltages. All windings are tested to EASA specifications using a Baker Motor Analyzer. Rewound motors undergo VPI impregnation to ensure insulation integrity and resistance to harsh industrial environments.
Vibration Analysis
Our vibration spectrum analysis employs SKF Multilog IMx-S equipment with a 120 dB dynamic range. Engineers compare 30+ years of historical data to identify anomalies, ensuring motor integrity before shipment. This proactive testing reduces unplanned downtime and identifies bearing wear or shaft misalignment before installation.
Machine Shop Services
Our in-house machine shop handles complete motor refurbishments, including bearing housing machining and shaft dimensional checks. Three full-time machinists perform precision work to maintain proper diametrical clearances for thermal growth. We replace bearings with SKF or NTN components, ensuring OEM-quality replacements without outsourcing delays.
24/7 Emergency Response
We provide 24-hour emergency motor repair services with straight-time rates for weekdays between 6 a.m. and 11 p.m. Our technicians offer rapid pickup/delivery using a 60,000 lb crane for oversized equipment. Emergency calls are prioritized, with vibration engineers available to assess motor integrity and expedite repairs for critical industrial operations.
