The Eon 42 variable-speed, constant-torque motor is designed for direct-drive blower applications such as fan coils, kitchen ventilators, air curtains, and unit heaters/coolers. According to the ...

PSC motors rely on the rotating magnetic field that is generated by the applied alternating voltage and corresponding alternating current to turn the rotor. The magnetic field rotates at 3,600 rpm (60 ...

The MFW fixeddisplacement motor maintains constant torque with varying horsepower. The MVW variabledisplacement motor operates with constant horsepower and variable torque or constant torque or ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

If you run your variable frequency drives at 60 Hz and below, you are not alone. Nearly all the VFDs in North America operate below this nominal frequency threshold. Yet a growing number of ...

[James Bruton] is experimenting is a series of interesting mechanical mechanisms, the latest being a CVT transmission system which uses a tilting sphere to get a variable speed output from a constant ...

Variable speed motor controllers regulate the speed and/or torque of asynchronous motors. Depending on the application, there are controllers from a few hundred Watts up to several hundred Kilowatts.

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...
