Leeson / Regal Beloit Motors and Speed Reducers

The LEESON brand spans more than 6,000 stock AC and DC motors, gearmotors and variable-speed control solutions. All are built for rugged commercial and industrial applications. Whether you need thousands of motors for OEM applications or a single replacement motor, count on our twenty-three stocking warehouses in the USA to get it there right when you need it. Whether you need a motor that withstands extreme temperatures, utilizes a unique mount or other requirement, we have solutions. Look to LEESON brand motors for innovative custom solutions, and personalized service.

Leeson ProductsAC and DC Motors

Our stock motor lineup includes AC and DC designs in sub-fractional through hundreds of horsepower sizes for general purpose use and specific-duty applications. All popular enclosures and configurations are available, along with some not-so-easy-to-find items. For an extra margin of protection from inverter-induced voltage spikes, LEESON’s Inverter Rated Insulation System (IRIS) comes standard – at no extra cost on all stock NEMA three-phase motors (1HP and larger).

Adjustable Speed Drives

Speedmaster drives are a perfect fit with many types of LEESON three-phase motors. Our Micro Series inverter line is available through 60HP at 230 Volts, and through 150 HP at 460 Volts. Micro Series offers easy-to-use, English programming with built in PID software, making them closed-loop drives, if needed. For applications through 25 HP, choose the SM-Plus Inverter with its miniscule footprint, big-drive features and wide range of accessories. If you require a simple “shaft-turner”, select economical SM-Series drives, which feature the same small footprint and many features of our SM-Plus Series. Vector inverters with 200% starting torque – when run with a vector duty motor –provide full output torque down to 1HZ, in both NEMA 1 and NEMA 4X enclosures. And, look to LEESON for a competitive line of SCR, PWM, Regenerative and Low Voltage DC Controls.

Product Groups

AC Controls

LEESON Speedmaster inverters, or variable frequency drives, are feature rich controls offering great process control and operating efficiencies for your AC Motors. With our broad family of controls, we have the solution for your application needs.

AC/DC Gearmotors

LEESON right angle and parallel shaft gearmotors are offered in both AC and DC Designs. These industrial strength gearmotors are designed for reliability and long life in the toughest applications.

Definite Purpose AC Motors

Motors constructed to meet varying application needs ranging from automotive duty, aggregate duty, air compressors, pressure washers, unit handling, to woodworking motors and more.

Explosion Proof Motors

Specialized motors for hazardous environments where fire or explosive agents are present. LEESON explosion proof motors meet varying electrical codes including UL Division I or Division I.

Farm/Agriculture Motors

For more than 40 years, the LEESON brand has designed, engineered, and built motor solutions to handle the high-starting loads and severe-duty applications of the Farm/Ag industry. Designs include general purpose, crop dryer, auger drives, fan ventilation, grain stirring and more.

General Purpose Motors

Hundreds of industrial designed “off-the-shelf” motor solutions including totally enclosed and drip-proof enclosures, rolled steel and cast iron frames, and single or three phase motors. The LEESON line of general purpose motors can be used in many applications including compressors, conveyors, pumps, fans plus many others.

HVAC Motors

Industrial, commercial, and agricultural HVAC fan motors designed for harsh HVAC applications ranging from condenser fans, crop dryer fans, to cooling tower fans.

Pump Motors

Specialized motors for the pumping industry featuring Jet pump, JM & JP pump, carbonator pump, and fire pump motors with variations for washdown applications or explosion proof environments.

Severe Duty Motors

LEESON motors designed for harsh environments featuring cast iron frames, totally enclosed enclosures, as well as IEEE-841 designs to withstand the toughest industrial applications found in refineries, mines, foundries, paper and pulp mills, cement plants, and other severe duty applications.

Special Voltage Motors

Designed for use where special voltages are required including 575V, 200/400V, or 50Hz commonly found in pumps, compressors, fans, blowers, or other industrial applications.

Variable Speed Motors

Inverter or vector duty motor designed for use in constant torque speed control applications found on conveyors, material handling, pumps, and fans. Models feature varying speed ranges including 4:1, 10:1, 1000:1, and 2000:1 and offer encoders or encoder provisions.

Washdown Motors

Whether you need a motor that handles an occasional splash or a solution that can handle continuous washdown 24/7, LEESON Washguard industrial-duty motors can take it. Choose a solution that’s USDA approved, FDA approved, BISSC certified, or has an IP69 enclosure protection – to name a few.
