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 ...

Choosing the right motor and VFD type depends on a variety of factors; however, it is necessary to analyze how the motor changes when the speed is reduced. The experts at eMotors Direct outline ...

The MSC-1 is an advanced speed controller for the company's AC speed control motors. Related To: Oriental Motor USA The speed controller connects directly to a PLC or computer and features two speed ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

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 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 ...

For the PDF version of this article, click here. More than 80% of the motors bought each year continue to be low-cost single-phase ac motors. Because these motors are not very efficient when ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

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.
