The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

Insistent demand for energy-saving industrial and home appliances has recently escalated because of energy and environmental matter and the necessity to comply with new energy consumption regulations.

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 ...

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 ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

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

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Legacy designs of variable frequency drives (VFDs) used optocouplers or pulse transformers for isolation and mated them together with gate driver ICs. A more integrated approach, though, uses ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

PROVO, Utah--(BUSINESS WIRE)--Raser Technologies, Inc. (NYSE Arca: RZ) (“Raser”), a technology licensing company established to develop and license advanced electric motor, controller and related ...

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...
