International Appliance Manufacturing 2008 - (Page 22) it as a transition effect or a full filter, dust obstruction and even an unbalanced fan. The computing power of the inverter electronics is also able to integrate the logic for the most sophisticated user interfaces and other features such as remote control and smoke/fumes sensing. ATech has extensive know-how in various user interfaces, from »ONE-TOUCH« technology and capacitive keyboards to RADIO FREQUENCY and infrared remote controls, or devices connected via ZigBee. The product can also integrate a proprietary, cost-effective smoke and fumes detection for automatic operation function. Improvements Possible by Other Motor Technologies The inverter technology practically allows the use of a 3-phase motor on the single phase mains supply. This widens a range of motor technology possibilities, from low cost 3-phase AC induction motors to Brushless DC and Permanent Magnet AC motors. All these motors feature significant improvements in efficiency, while the 3-phase AC and Permanent Magnet AC motors also feature lower noise levels (see table 1). size inverter in the wiring of the rangehood, with no changes to the motor whatsoever, is fast and easy and allows several additional features: stepless speed selection, speed increase, advanced status sensing, and many others. ATech’s inverter products for rangehoods are universal and the performance fine-tuning is performed at ATech laboratories. Further improvements are possible by changing the motor technology to BLDC, 3-phase AC induction motor or Permanent Magnet Alternating Current (PMAC) motor for the lowest noise. ATech has considerable know-how in integrating user interfaces, smoke and fumes detection and various remote control functions. Summary In order to increase the efficiency of most popular rangehood types there is no need for major design changes.
