  2. Variable-frequency drive - Wikipedia

    en.wikipedia.org/wiki/Variable-frequency_drive

    Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...

  3. Motor drive - Wikipedia

    en.wikipedia.org/wiki/Motor_drive

    With a variable-speed drive on the pump or fan, the supply can be adjusted to match demand and no extra loss is introduced. For example, when a fan is driven directly by a fixed-speed motor, the airflow is designed for the maximum demand of the system, and so will usually be higher than it needs to be.

  4. Variable-speed air compressor - Wikipedia

    en.wikipedia.org/wiki/Variable-speed_air_compressor

    A variable-speed drive (VSD) air compressor is an air compressor that takes advantage of variable-speed drive technology. This type of compressor uses a special drive to control the speed ( RPM ) of the unit, which in turn saves energy compared to a fixed speed equivalent. [ 1 ]

  5. Vector control (motor) - Wikipedia

    en.wikipedia.org/wiki/Vector_control_(motor)

    In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...

  6. Vacuum fluorescent display - Wikipedia

    en.wikipedia.org/wiki/Vacuum_fluorescent_display

    A vacuum fluorescent display (VFD) is a display device once commonly used on consumer electronics equipment such as video cassette recorders, car radios, and microwave ovens. A VFD operates on the principle of cathodoluminescence , roughly similar to a cathode-ray tube , but operating at much lower voltages.
