Motors help reduce energy consumption

By Design World Staff | February 21, 2007

The Department of Energy begins a five year phase-in of tough energy standards that will affect several types of white-good appliances. The goal is to reduce energy usage and the need to build additional carbon dioxide emitting power plants.

The latest brushless dc motor technology improves motor efficiency, which can result in lower energy consumption. The BLDC25-OR brushless dc motors from Hansen Corp., for example, produce a continuous maximum power of 3 W with 70% efficiency.

The motor family handles applications where little space is available or cost is a key driver, such as building automation, climate control, office equipment, pumps, fans, and medical devices. The motors have a 1-in. outside diameter, with lengths from 0.5 to 1 in. The 3-phase brushless dc motor includes 3 hall sensors for exact positioning and smooth running. The 12-pole design has positioning feedback of 36 ppr without an additional encoder.

The motors also have two high-end NMB ball bearings for long life. And the brushless design eliminates wear or debris, and reduces RF noise levels, making EMI problems insignificant.
