  • Design Considerations in Using the Inverter Gate Driver Optocouplers for Variable Speed Motor Drives - White Paper (.pdf)
    Inverter Gate Driver optocouplers are ideally suited for IGBT and MOSFET applications for variable speed motor drives. Their high output peak currents coupled with high voltage safety standards certified galvanic insulation, very high common mode noise rejection isolation, solid state device level
  • Matching compressors to variable-speed drives
    converter is not constant over the complete control range. Between 70 and 30% of full flow, or speed, efficiency is reduced from 94 to 86% for a 94-kW motor, for example. Added to this are losses in the frequency converter and the nonlinear performance characteristic of the compressors. If variable-speed
  • ECM 3.0 Motor Troubleshooting (.pdf)
    The next generation variable speed motor model 3.0 entered the residential HVAC marketplace sometime in 2008. This model has a few notable external changes from its predecessors. The 16-pin communication connector has been replaced with a 4-pin connector, the control has been reduced in size
  • Variable-Pitch Drives
    Variable-pitch drives are the simplest of all mechanical adjustable-speed mechanisms. Most of these drives use rubber belts. However, chain types are unmatched in regard to its particular strong points. Belt and chain adjustable-speed drives are "adjustable" in two senses. One type, with stationary
  • Replacing a Mechanical Adjustable Speed Drive with a Variable Speed Drive
    motor is connected to a variable diameter sheave (item A in Figure 1) that transmits power through a belt to another variable diameter sheave (Item B). An internal gearbox can then be used to further reduce speed as necessary. The variable sheave/belt assembly will act as a reduction gear up
  • Appliance motors turn green
    induction motors dominated the fixed-speed appliance era, but are not necessarily the best choice for variable-speed schemes. For example, controllers, for those motors able to manage the high dynamic torque washing machines require, are expensive to create. An alternative motor type
  • Motors Move Toward More Efficiency
    an old-style constant- speed motor with one capable of operating at variable speeds. Then optimize its operation for the conditions at hand. The quest for efficiency.

  • Green Technology: More-Efficient Motors
    avenue for energy savings is in running motors at variable speeds. The ability to work efficiently at less than rated speed brings obvious benefits. Permanentmagnet- rotor motors can have efficiencies exceeding those of NEMA Premium units by a few percentage points, even at sizes of 500 hp and larger
