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 ...

These drawbacks hinder control improvements to single-phase induction motors to meet mandatory regulatory features, customer attractiveness, and product flexibility. In contrast to single”phase ACIM, ...

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 ...

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...

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 & ...

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

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, ...

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 ...

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is.

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 ...
