Energy efficiency is a key driving force for the growing adoption of variable-speed drives in motor-control applications, according to John Pocs, senior systems applications engineer at NEC ...

Variable speed control of a compressor motor significantly reduces both the peak and average energy consumption. However, since the standards for air conditioners require a reduction in the seasonal ...

Traditionally, DC motors have been used in precise speed control applications because of their ability to provide acceleration and deceleration from a dead stop position to full speed fairly easily.

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 ...

It's easy to understand how variable-speed motor drives benefit pumps and blowers from the energy curves that depict their performance.

Consumer appliance and industrial applications are generating demand for sophisticated motor control circuits that can simplify system designs, reduce ...

Motion-control algorithms run in a specialized chip called the IRMCF312, one of IR’s iMotion processors optimized for variable-speed motor control. About the Author ...

ECEA 5341 Motors and Motor Control Circuits ECEA 5341 Motors and Motor Control Circuits 2nd course in the Embedding Sensors and Motors Specialization. Instructors: Jay Mendelson, MSME, Lecturer & ...

Controlling a motor’s speed and direction presupposes the mode of operation of the motor in use and requires different techniques and circuits depending on the type of motor and the different ...

The Ultratech™ variable-speed motor is a four-wire electronically commutated motor with two-way communication. The motor receives commands from the furnace system control board, executes the command, ...

Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a couple of typical scenarios commonly encountered ...
