Electronic commutation (EC) is the latest motor technology to be 

used in direct drive fans. Also known in the industry as Brush Free 

or Brushless DC, the EC motors utilize an electronic circuit board to 

control the functionality of the motor. The motor operates off of 

115V or 208/230V AC single phase power or 208/230V or 460 three 

phase power, which is converted to DC power within the motor’s 

circuitry.  The  result  is  a  highly  efficient  motor  with  an  expanded 

speed control range and a variety of speed control options from 

which to choose.

This manual has been prepared to guide the users of electronically commutated motors in the proper installation, operation 

and  maintenance  procedures  to  ensure  maximum  equipment  life  with  trouble-free  operation. 

For safe installation, startup 

and operational life of this equipment, it is important that all involved with the equipment be well versed in proper fan safety 

practices and read this manual. It is the user’s responsibility to make sure that all requirements of good safety practices and any 

applicable safety codes are strictly adhered to. 

Because of the wide variety of equipment covered in this manual, the instructions 

given here are general in nature. Additional product and engineering information is available at www.aerovent.com.
