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 ...

Since AC induction motors have been established as the preferred choice for industrial motors and the need for reduced power in all aspects of design is ever present, the efficiency of these motors is ...

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 ...

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 ...

Global demand for both energy and water conservation is having a tremendous impact on the home appliance market. The regulatory standards and recommendations are redefining a new generation of energy- ...

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 ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

The ES01/ES02 series of compact AC motor speed controllers can be used with the vendor’s World K and V series AC induction or reversible speed control motors. The ES01 accepts input power of 110/115 ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

STMicroelectronics has released the STM32 ZeST (Zero Speed Full Torque) software algorithm, designed to run on STM32 microcontrollers, that lets sensorless motor drives produce full torque at zero ...
