  • 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
  • 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
  • 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

  • Sensorless Field Oriented Control of PMSM Motors using dsPIC30F or dsPIC33F Digital Signal Controllers
    AN1078 Sensorless Field Oriented Control of PMSM Motors This application note focuses on the PMSM-based sen- Author: Jorge Zambada sorless FOC control of appliances because this control Microchip Technology Inc. technique offers the greatest cost benefit in appliance motor control. The sensorless
  • Attachment anxiety
    High-tech components used in appliances put more demands on adhesives and sealants. By Christine Salerni, Sean McGrath In clothes dryers, light-cure acrylics are used in motor assemblies for flange bonding and to coat and seal the laminate. New washing machines use toughened anaerobic threadlockers
  • Motors Move Toward More Efficiency
    The next generation of motor-powered appliances and industrial machines will be energy misers thanks to new electronics and speed controls. On hot sweltering days, it is easy to appreciate why air conditioners for 1.3 billion Chinese are a driving force behind more efficient motor control. "Almost
  • Warranty coverage: Avoiding self-inflicted wounds
    Recently, a national appliance company found itself in hot water because the specific language of the warranty it provided on a consumer product had unintentional coverage for the consumer. The company manufactures consumer and industrial versions of its products and warrants them accordingly
  • DSPs: Smarter than your average chip
    increasingly used in automotive, appliance, and industrial applications. DSPs in washing machines can improve the energy efficiency of motors by controlling the speed electronically rather than using traditional mechanical methods. Motorola's DigitalDNA line of DSPs can run speed estimation, PWM, and power
