When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

In low-cost, high-speed motor applications, especially those inside the home, the universal motor dominates. They are as ubiquitous as the countertop blenders and the power tools they inhabit. But not ...

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.

AC motors are abundant in the HVAC industry. Every fan and pump application requires an AC motor. For efficient and reliable control, adjustable-speed drives are becoming a common companion for these ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

LAS VEGAS — The term “higher efficiency” is used a lot throughout the HVAC industry. It’s an important facet of nearly every component associated with the market, and manufacturers are consistently ...

Updates to the JLG product lines include standard AC drive motors, lithium-ion battery options and a range-extending genset charging option. JLG has introduced new features and options for its line of ...

Inventing elegant solutions to complex problems is a Honda specialty. When the first hybrids arrived in the U.S., Honda beat Toyota to the market, barely, by simply installing a pancake AC motor ahead ...
