It shows the vector motor control and one the of best sensorless vector control frequency inverters. Vector control is one of the most popular electrical motor control modes in electric industry that ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

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 ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

You can divide the world of electronic motor drives into two categories: ac and dc. A motor drive controls the speed, torque, direction, and resulting horsepower of a motor. A dc drive typically ...

If you run your variable frequency drives at 60 Hz and below, you are not alone. Nearly all the VFDs in North America operate below this nominal frequency threshold. Yet a growing number of ...

Electric motors fitted with variable frequency drives are at risk of bearing damage due to a build-up of current in the rotor that discharges through the shaft, damaging the lubrication and bearing ...

Ivor Vidjen, Global Head of Strategy and Business Development for Low Voltage IEC motors at ABB, explains the customer value of an integrated one-stop-shop for electric drivetrains. Variable frequency ...

The experts at eMotors Direct outline how VFD’s can damage bearings and discuss preventative measures to prevent VFD induced bearing damage Electric motors fitted with VFDs (Variable Frequency Drives) ...
