What is the purpose of VFD drive?

A VFD (Variable Frequency Drive), or rather a VVFD (Variable Voltage and Frequency Drive) is a precision electronic device specifically designed and used to control the speed of AC induction motors (single as well as three phase) without affecting the electric consumption, torque, impedance, magnetic flux, etc.

How does VFD control motor speed?

VFDs can be used to control AC motor speeds by changing the motor’s frequency without sacrificing the output power of the motor. This is done by turning the speed pot (explained in section three) of an AC motor drive. Visit the blog “What’s Your Frequency” for additional information regarding motor frequencies.

How many types of VFD are there?

There are two major types of variable frequency drive on the market: mechanical and electrical. Mechanical VFDs include the following subtypes: Variable pitch drive – a belt and pulley drive where the pitch diameter of one or both pulleys is adjustable, giving a multi ratio and hence a variable output speed.

What is the principle of VFD?

According to the variable frequency drive working principle, it’s the electronic controller specifically designed to change the frequency of voltage supplied to the induction motor. In the 1960s, VFDs had rather small solid-state components that limited the amount of current the VFD could supply to the motor.

What is the benefit of VFD?

As one of the main advantages of using a VFD is the energy cost savings associated with speed control. When using belts, sheaves, or gearboxes to reduce speed, the motor still runs at full speed; however, a VFD reduces the actual motor speed, which reduces the amps drawn by the motor.

Can I put a VFD on any motor?

1. If the Motor is pre-EPAct (1992), it should be run on VFDs only with careful consideration. Motors made during that time were not made for VFD use, but if they are VFD rated, will be okay. Class F insulation or higher is suitable for VFD use, but VFDs may have no more than a 2:1 Constant Torque ratio.
