120 Volt Single-Phase Electric Motors
120-volt electric motors operate on the most common power supply in North America — the same single-phase 120 V line used in workshops, garages, and small facilities.
These motors are designed for compact machinery, portable equipment, and light industrial applications that demand dependable torque with minimal installation complexity.
Available in Open Drip Proof (ODP) and Totally Enclosed Fan Cooled (TEFC) designs, 120 V motors provide cost-effective power for pumps, fans, and tools that run on standard 120 V AC circuits.

When to Choose a 120 V Motor
Application Scenario
Shops & Garages Runs on standard outlets — no transformer or three-phase supply needed.
OEM Equipment Ideal for small compressors, blowers, conveyors, and test stands.
Portable Machinery Compact and lightweight for tools and transportable units.
Rural or Temporary Sites Simple plug-in installation without industrial power infrastructure.
Enclosure Options
Performance and Efficiency
Despite operating on standard household voltage, modern 120 V motors achieve NEMA Premium® efficiency levels through improved winding designs and balanced rotors.
Paired with high-efficiency fans and sealed bearings, these motors deliver consistent service in continuous-duty applications.
Typical Applications
Air compressors and small pumps
Fans and ventilators
Conveyors and feed systems
Bench-top machinery and OEM assemblies
Portable tools and wash-down equipment
