Profile: Electric Motors & Specialties, Inc. designs & manufactures unit bearing fan motors. These motors are suitable for a wide range of fan applications. We provide fan motors, fans, agitator motors, and accessories to original equipment manufacturers in the domestic & commercial refrigeration industry. The brands we offer include Electric Motors & Specialties™ and Unitronix™. Our ESP water agitator motor is designed for the drink dispensing industry. Its construction allows for continuous no air over motor operation. The typical heavy side-bearing loads in these long shaft applications are effectively handled by the dynamic oil system, durable cast-iron bearing and hardened stainless steel shaft. A variety of shaft lengths are available. The SPFB and S4B motors are totally enclosed cast iron 4-pole fan motors. They are designed to be used with propeller fan blades from 6 to 10 inch diameter. Both designs utilize the combination of a cast iron bearing, hardened steel shaft and hydrodynamic thick film lubrication system for unparalleled durability.
