The DynaMotor from DynaMotors Inc., Warrensville Heights, Ohio (dynamotors.com), uses optically controlled solid-state switches embedded in the rotor windings to control current and, thus, torque, ...

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% ...

Over 50% of Earth’s total electricity consumption is used for operating motors and motor systems. HVAC contractors and technicians encounter motors in a variety of different applications, and aspects ...

ABB is changing the energy efficiency game with its innovative LV Titanium Variable Speed Motor (VSM) platform that makes ...

For many retrofit projects, the use of a VFD seems like a “no brainer.” Drives are now cheaper and more reliable than ever, and the benefits of efficient control of motors can’t be beat. Still, there ...

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, ...

Fairchild Semiconductor developed the FTC03V455A1 a 3-Phase, Variable Speed Drive Automotive Power Module intended for 3-Phase motor control applications under 2kW, allows designers to reduce the ...

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 ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...
