Premium Efficiency
“Super-E-motors” are designed to save energy. These premium efficiency motors are available in fully sealed (force-cooled) and splash-proof versions. All three-phase motors are suitable for frequency control in accordance with the MG1 NEMA standard, section This means that the 230V and 460V motors are capable of withstanding peaks of up to 1600V. These Baldor Premium Efficiency motors are also available in single-phase versions.

Single Phase
We supply the following motors for single-phase applications: 1/12HP up to 15HP in TEFC and ODP versions. Supplied standard with a foot, but also available with C-face foot and C-face footless. From 1/4HP to 5HP these motors are available as Super-E ® Premium Efficient motors for situations in which energy has to be saved.

Smaller capacities
The Baldor range of small-capacity motors is designed for use in low to medium initial torque applications. These motors typically offer high-quality at a very attractive price. The entire line is designed for NEMA 48 and 56 motors, from 1/4HP to 1HP. They are available in both single and triple-phase versions. The most common applications include: Jet pump, heating and cooling, ventilation, air-conditioning, blowers, direct-drive blowers, condensation blowers and standing blowers.

F-2 Mounting
Motors designed for applications with a F-2 mounting are available from stock from 1/2HP to 60HP. These Baldor motors are manufactured both in TEFC and in splash-proof versions, suitable for NEMA frame sizes 56 to 364T. Most capacities fall in insulation class F, with temperature increases in line with class B and a service factor of 1.15.

These motors are available in Standard High Efficiency and Premium Efficiency versions.

Agriculture and Horticulture
These Baldor motors are designed for use in a wide variety of applications in the on farming and greenhouse industry. We supply motors that are suitable for aeration fans, drilling drives, grain mixers, dosage pumps, direct conversion, irrigation drives and crop-drying installations. Available in single and triple-phase, TEFC and ODP (splash-proof) versions. Especially suitable for applications that are difficult to start-up and require additional initial torque. Baldor is the only manufacturer that keeps Repulsion-Start Induction Run motors on stock, from 2HP to 10HP.

General applications
The extensive range of Baldor all-round motors is available in splash-proof and TEFC design versions, both single and triple-phase. Motors from 1/12HP to 1500HP are available from stock. The applications for these motors include: Compressors, pumps, blowers, conveyor belts, material handling and machining. Also available from stock are motors designed to directly fit Pre-1952 NEMA frames.

HVAC (heating, ventilation and air-conditioning) motors. Baldor’s HVAC motors feature dynamical balanced rotors for less vibration and more silent operation. The motors vary in capacity between 1/4HP to 100HP and are available for use in heavy industry as well as for use in less demanding commercial applications. Applications include blowers, direct and belt-driven blowers, exhaust fans, heating systems, air conditioners and commercial cooling systems. We also supply specially developed low-energy motors for use in applications with a variable torque.

Frequency controlled
These Baldor motors are wound with 200 C, moisture-resistant ISR (Inverter Spike Resistant) winding wire, which considerably prologues their lifespan. Motors from 1/3 to 1000HP are available from stock. Frequency controlled motors are designed for use in applications that require a wide range (1000:1) and a constant torque. Applications include conveyor belts, pumps, blowers, metal processing, compressors, testing equipment and material processing machinery.

Motors for high-pressure cleaning
These single-phase Baldor motors are available in fully encapsulated (force-cooled) and splash-proof versions. Industrial quality with moisture-resistant winding wires capable of withstanding temperatures up to 200º C. The motors are UL and CSA-certified. NEMA versions with frame sizes from 56 to 184 with stand, or NEMA C-face flange with foot.

Two Speed motors
Our two-speed motors are available in fully sealed (force-cooled) and splash-proof versions. Our constant or variable torque motors with single or double winding are available in NEMA versions from 56 to 284T. Applications include ventilators, blowers, pumps, processing machines, hoists and conveyor belts.

Unit Handling
Baldor Unit Handling motors are designed for use in a wide variety of applications, including luggage handling, conveyor belts, packaging equipment, processing machines, hoists, lifts and door openers. Motors from 1/2HP to 10HP (56 to 215T versions) are available from stock, with or without Dodge D-series breaks. The 56 and 140T versions feature an over-dimensioned, top-mounted terminal box, which makes these motors easy to connect. Also available are foot-mounted versions with slits for easy assembly.
