The term refers specifically to electronic drives.

Vfd electric motor control.

Worldwide fse has earned a strong reputation for providing well engineered reliable and cost effective vfd sync bypass switchgear soft starters programmable logic controllers motor control and technical products and services. The hyundai n700e series high performance drive we offer is very easy and efficient to use. A vfd is a variable frequency drive. We look forward to working with you on your next critical project.

Medium voltage variable frequency drives vfds vfd accessories. Other names for a vfd are variable speed drive adjustable speed drive adjustable frequency drive ac drive microdrive and inverter. Teco variable frequency drive 1 hp 115 volts 1 phase input 230 volts 3 phase output l510 101 h1 vfd inverter for ac motor control 4 6 out of 5 stars 32 200 00 200. A variable frequency drive vfd is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor.

Ac motor main drive controller assembly and drive operator interface. Keypads parameter units. A vfd control system consist on an ac control panel housing the vfd and any associated motor control or circuit protection devices in an enclosure protecting them from electrical shocks fires moisture corrosion dust and other conditions. Vector control also called field oriented control foc is a variable frequency drive vfd control method in which the stator currents of a three phase ac electric motor are identified as two orthogonal components that can be visualized with a vector.

It s an all embracing term which can describe drives used to control both ac or dc motors or technically even mechanically controlled speed devices. Variable frequency drive vfd is a technique often used to achieve the adjustable speed drive of ac motors to control its speed as well as torque. Motor control centers mcc motor contol center mcc buckets. A variable frequency drive is a device used in a drive system consisting of the following three main sub systems.

One component defines the magnetic flux of the motor the other the torque. Need for variable speed drives before going into the details of variable frequency drive system let us take a look at the need for variable speed operation of an electric motor. Our line of variable frequency drives vfd control electric motors by varying their voltage and frequency during operation. The most common nema ratings for vfd control panel enclosures are nema 12 nema 3r and nema 4x.

In actual everyday usage it s most commonly used in the context of electric ac or dc drives. Frequency or hertz is directly related to the motor s speed rpms.
