Northwest Motor Service Areas of Expertise

Northwest Motor Sales & Service is a future-focused organization with an emphasis on uptime and reliability. We offer engineered solutions to your complex motor and drive systems. We provide a complete package of predictive and preventative services including vibration analysis, AWA and PdMA motor testing, laser alignments, base/foundation modifications, synchronous exciter upgrades and much, much more.

Our Longview factory is brand new (2017) and features 40T crane capacity, an 8′ VPI system, dynamometer and other equipment to provide our customers with consistent and reliable repairs.


Our standard testing includes Resistance, Meg-Ohm, Polarization Index (PI), Step Voltage, and a Surge Test. These tests, used together, offer a maintenance professional a complete analysis of electric motor insulation. We use SKF (Baker) AWA and PdMA test equipment depending on customer preference.

Our dynamic motor test equipment is capable of separating electrical issues from mechanical issues as well as defining power-related problem areas. We will provide valuable information regarding incoming power, voltage levels, imbalances and harmonic content. Single occurrence or trending overtime is available.
