The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

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 ...

The AC induction motor (ACIM) is the most popular motor used in consumer and industrial applications. The motor is highly reliable, as its simple design has no brushes that could wear out, and it can ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

Electric motors consume almost half of the electricity produced worldwide. They, in fact, provide the necessary driving force for much of today’s equipment. Motors, pumps, and fans are present in an ...

The road to energy efficient HVAC may lead to variablespeed compressor technology and new electronics to drive it. Most engineers know that heating, ventilation, and air conditioning (HVAC) systems ...
