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 ...

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 ...

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 ...

Adjustable-frequency drives have been billed as an energy efficient way to drive three-phase ac induction motors. Nevertheless, designers should understand that motors fed by inverter power experience ...

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 ...

Geothermal power offers a stable, continuous source of renewable energy that could help power millions of homes while reducing dependence on fossil fuels. As governments worldwide pursue ...

There’s great potential in salvaging a motor from a broken appliance, but so often the part in question is very specific to its application, presenting a puzzle of wires to the experimenter. This was ...

Co-founded by Suyash Mishra (B.Tech Electrical Engineering, IITRAM, 2022) and Gajendra Jain, Gati Drives addresses the critical challenge of India's dependence on imported, expensive BLDC motors while ...

Washing controls have used power inverters to control motor speeds for years. Variable-speed control enables a significant simplification of the mechanical system by replacing a clutch and gearbox ...
