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 ...

Motors are driving demand for electricity, accounting for about half of the electricity we consume, according to the Electric Power Research Institute (EPRI). Many of these motors are found throughout ...

In addition to industrial applications of variable-speed motor drives, the home appliance market is another major area where three-phase pulse width modulated (PWM) motor control drives are finding ...

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 ...

Hydrostatic drives are widely recognized as an excellent means of power transmission when variable output speed is required. Typically outperforming mechanical and electrical variable-speed drives and ...

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 ...

Another method worth considering in any discussion of motor control isvector control. The detailed formulation of this method to control thetorque and flux in PMSM was originally achieved by Jahns, ...

Due to economic necessity, commercial ship operators have become increasingly focused on finding cost-optimized solutions to operate their vessels. In turn, power solutions providers like Rolls-Royce ...
