  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 ...

    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 ...

    For the same application, the program would select a 125 kW gen-set when using a variable frequency drive and a primary reactor bypass with a 30% starting voltage drop, cutting the gen-set in half (Slides 36–39). [5] Energy Savings – "Most motors turn at nearly constant speed. However, much of the time the devices they drive operate at less ...

    A full view of a typical vacuum fluorescent display (VFD) used in a videocassette recorder. Before the advent of on-screen displays, the only interface available for programming a home video recorder was a small VFD, LED or LCD panel and a small number of buttons. Correctly setting up a recording for a specific programme was therefore a ...

    The calculator is fully compatible with the second-generation models (B3-34 and MK-54), using the same command system and machine codes. On average, a program that takes all 105 steps of program memory and 15 registers on the MC-52 will be equivalent in capability to approximately 140-150 steps and 18 registers on the B3-34.
