                ELECTRONICALLY COMMUTATED MOTORS (ECM)
 ECM
 We Have the Broadest Offering in the Business
Electronically Commutated Motors (ECM) are ultra high efficient brushless DC motors that uti- lize a permanent magnet rotor and built in inverter that converts the incoming AC power to DC. DC motors are inherently more efficient and easier to control than traditional induction motors. Escalating energy costs are driving the demand for ECM technology.
  Commercial Refrigeration Motors That Deliver Energy Saving
ARKTIC 59 ( See P. 116) • High efficiency (65%) uses
ECM Fan Kits ( See P. 116)
• High efficiency (68%) fan/motor
  less energy & produces less
air moving system
• Direct replacement for
waste heat
• 3.3” drop in replacement
• For walk in coolers / freezers • Saves $100/Yr.*
Hussman, Hill, and Tyler (& select unit bearing/fan appli- cations)
                  Packard ( See P. 112)
• High efficiency (68%) uses
• Saves $26/Yr.*
• For refrigerated cases
   less energy & produces less
X-13 Replacements ( See P. 88 & 89)
