Fractional HP Motors

Fractional horsepower (HP) motors are electric motors rated at less than one horsepower and are commonly used in applications where compact size and moderate power output are required. These motors play a critical role in a wide range of residential, commercial, and industrial equipment, including fans, pumps, conveyors, HVAC systems, and small machinery. RSP Supply offers a comprehensive selection of fractional HP motors designed to meet diverse operational requirements.

Designed with space efficiency in mind, fractional HP motors are compact and lightweight, making them well-suited for installations where mounting space is limited. Despite their smaller size, these motors are engineered for reliable performance and are capable of delivering consistent output under demanding operating conditions. Their design helps minimize overall system weight while maintaining dependable operation. Fractional HP motors are available in both single-phase and three-phase configurations to accommodate different power sources and application needs. Single-phase motors are typically used in residential and light commercial environments, while three-phase motors are preferred in industrial settings where higher efficiency and smoother operation are required. Trusted manufacturers such as Baldor-Reliance and Nidec provide motors known for durability, efficiency, and long service life.
