50 HP Electric Motors (50 Horsepower Industrial Motors)

50 HP electric motors provide the strength and efficiency required for industrial operations where consistent power and reliability are essential.
These 50 horsepower motors are designed for continuous-duty performance, offering dependable operation for pumps, conveyors, compressors, and process equipment.

Available in ODP, TEFC, and Explosion-Proof (TEXP) enclosures, each 50 HP motor is built to NEMA and CSA/UL standards, combining rugged construction with high mechanical efficiency.

What Does a 50 HP Motor Offer?

A 50 horsepower motor delivers approximately 37.3 kilowatts of output power, making it ideal for heavy-duty mechanical drives and continuous industrial use.
Most 50 HP units are built in NEMA frame sizes 326T–326T, providing robust bearings and shafts for longer service life under demanding load cycles.

Key features include:

  • Premium efficiency rating (NEMA Premium® compliant)

  • Available speeds: 1800 or 3600 RPM

  • Voltage options: 230/460V, 575V (3-phase)

  • Multiple enclosures: ODP, TEFC, and TEXP

  • Rugged construction for vibration and heat management

Enclosure Options — ODP, TEFC & TEXP

Each enclosure type offers distinct advantages depending on your environment:
