Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

Insistent demand for energy-saving industrial and home appliances has recently escalated because of energy and environmental matter and the necessity to comply with new energy consumption regulations.

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 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 ...

Variable frequency drives convert ac power to dc and then reshape that current to control ac motors. All types control speed by varying current frequency, but one subtype — flux vector drives — uses ...

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, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...

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 ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...
