Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

Hitachi America, Ltd., Industrial Components and Equipment Division, today announced the introduction of the L700 Series of Industrial AC Variable Frequency Drives. The L700 significantly expands on ...

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

A line of ac variable-frequency drives includes a high-torque sensorless micro drive (SJ100), a high-performance field-programmable drive (SJ300), a drive optimized for fan and pump applications ...

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 ...

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 ...

The ALX Series AC variable-frequency drive is now available in ratings up to 600 hp. According to the manufacturer, with the flexibility of flux vector technology, this drive can be used for standard ...

LONDON--(BUSINESS WIRE)--Technavio has been monitoring the global variable frequency drives market since 2016 and the market is poised to grow by USD 5.11 billion during 2019-2023, progressing at a ...

A recent trend in nuclear power plant upgrades has been the replacement of the motor-generator (MG) sets that drive the reactor circulating pumps with variable-frequency drives (VFD). Siemens’ first ...

New York, United States , May 26, 2023 (GLOBE NEWSWIRE) -- The Global Variable Frequency Drive Market Size is to grow from USD 22.16 billion in 2022 to USD 36.79 billion by 2032, at a Compound Annual ...

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...
