In addition to industrial applications of variable-speed motor drives, the home appliance market is another major area where three-phase pulse width modulated (PWM) motor control drives are finding ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Demand is growing for appliances such as washing machines, refrigerators, and air conditioners to help improve domestic energy efficiency. Moving from conventional fixed-speed motors to variable-speed ...

Discover how 24V BLDC motors enhance HVAC efficiency and reduce maintenance costs. Learn key selection tips on torque, voltage, sizing, and system integration to ensure reliable, quiet, and ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can ...

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 ...

In an industry evolving alongside consumer concerns over rising energy costs, impact on the environment, and, of course, stricter regulations handed down by the government, new technologies are ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.
