Variable Frequency Drive Basics - Electrical A2Z

Variable Frequency Drive is a technology where the rotational speed of an electric motor is controlled or varied electronically.. Electric motors were invented in the early 1800's. These first electric motors ran off of DC (Direct Current) because that was the only electricity available at the time. DC motor operating characteristics are determined by the physical motor design (i.e. the ...

Principles of Operation - AC VFD Drives | Natural ...

A variable frequency drive controls the speed of an AC motor by varying the frequency supplied to the motor. The drive also regulates the output voltage in proportion to the output frequency to provide a relatively constant ratio of voltage to frequency (V/Hz), as required by the characteristics of the AC motor to produce adequate torque.

Working Principle of Pulley, Pulley Manufacturer, Supplier ...

As Pulley is a type of simple machine it helps to reverse the direction of lifting force. When one end of the rope is pulled downwards, the load on the other end of the rope is pulled upward. Therefore, the direction of force is changed from downwards to upwards. Pulley can work on one, two and four wheels.
