  • Appliance motors turn green
    to traditional fixed-speed units. Variable-speed systems also let designers specify smaller and less-expensive motors and thereby continue to offer attractive prices to consumers. Low-cost induction motors dominated the fixed-speed appliance era, but are not necessarily the best choice for variable-speed
  • CMOS Isolators for Home Appliance Motor Control
    The home appliance market uses three-phase, pulse-width-modulated (PWM) motors in a number of end applications including air conditioners, washers, dryers and garage door openers. Many of these applications require variable speed and/or torque, and the controllers that provide this capability must
  • Breakthrough in DC Motor Technology Allows Innovation in Appliance Design and Manufacture
    innovation isn't a matter of adding a few new features or redesigning the look of a product. Innovation comes from pushing the envelope. The breakthrough motor technology we have developed in turn provides a platform for innovation in the appliance industry that can be configured for various
  • Motors Move Toward More Efficiency
    Product Management Director Aengus Murray. (Residential capacity in the U.S. is about 10 kW.) Nevertheless, Asia isn 't the only place where energy-efficient appliance motors are gaining traction. Appliances billed with green credentials are starting to sell in North America as well. "Two or three
  • Sensorless Field Oriented Control of PMSM Motors using dsPIC30F or dsPIC33F Digital Signal Controllers

The sensorless
  • Motor Control in Home Appliances
    The home appliance market uses three-phase, pulse-width-modulated (PWM) motors in a number of end applications including air conditioners, washers, dryers and garage door openers. Many of these applications require variable speed and/or torque, and the controllers that provide this capability must
  • Passive noise reduction - options for axial and centrifugal fans, Appliance DESIGN, February 2015
    One undisputed requirement for a high performance system is the. ability to closely match its output to the actual demand. Comfort, health, process variance, sound emissions, and energy performance benefit from enabling motors for variable speed operation. What are the potential side effects
  • Autotransformers
    for variable input applications. Advantages of autotransformers include relatively small size, due to the sharing of coils by the primary and secondary sides, and low cost for non-sensitive applications such as heaters and appliance motors.
  • Attachment anxiety
    identification tags on compressor motors. Cyanoacrylates also find use as instant adhesives in glassto-glass bonding of large shelf assemblies inside the refrigerator. Advances in appliance technology are bringing new roles for adhesives. Traditional uses still abound. For example, adhesives find
  • New ICs will make appliances more efficient
    of boosting efficiency while reducing part costs. PM synchronous motors work at variable speeds and may become part of the appliance structure itself, perhaps eliminating the need for separate gearboxes and belt drives used to harness power from induction motors.
