This article discusses developments in electric motors and drives that are boosting efficiency, simplifying setup, and cutting costs. New drives offer compact designs and simplified installation, and start-up. An inexpensive controller for single-phase ac induction motors has been developed by Anacon Systems Inc. of Springfield, Montana. The controller is targeted to a huge installed base of fan, pump, and compressor motors. The company also has introduced a Smartcom series of motor controllers specifically designed for residential and light commercial Heating, ventilation, and air conditioning (HVAC) applications. New products currently under development by Anacon Systems will extend the range of offerings to cover power ranges up to 2 hp. The company also plans to offer controllers for three-phase motors. A new energy-efficient integrated ac drive/motor, combining plug-and-play installation and compact design, has been introduced by ABB Drives & Power Products of New Berlin, Wisconsin. The new drive has power cables at the bottom rather than on the side. The drive's compact size allows it to fit into many retrofit spaces and frees up panel space that would be occupied by a larger drive, according to ABB.
