Air & Gas Compressors

The U.S. MOTORS® brand, manufactured by Nidec Motor Corporation, is one of the oldest and most respected in the motor industry. Today, our brand is recognized worldwide as a leader of technological innovation in industrial and compressor motors. We offer a wide range of motors specifically designed to meet the unique needs of the compressor industry. Our products are designed to be safe, energy-efficient and durable.

When you need a motor designed for rotary screw, reciprocating or centrifugal compressor applications, trust our U.S. MOTORS brand products to provide custom-made or stock solutions. Let us put more than 100 years of expert engineering and design to work for you. If our extensive stock motor inventory won’t fit your needs, our Commercial Engineering group can customize or design a compressor motor specifically for your application.

OEM Customized Designs:
We understand the unique challenges of powering compressors, from specialized bearings and shafts to the management of starting and breakdown torques. Our goal is to design a product fit to your specific requirements rather than taking a “one size fits all” approach.

Application Engineering:
If your compressor specifications require an engineered to order motor, our experienced engineering teams will design a customized solution for your application. Whether building a brand-new product or redesigning an existing line for better performance and reliability, we have the technical engineering team that can offer the perfect solution.
