What is a motor drive? Summary for design engineers
Some drives are wholly incorporated into the controller, so that the profile generation takes place in the controller as well as the torque command for the motor. On the other hand, a drive can also refer to the specific power electronic circuitry needed to drive the motor. Electric motors that drive industrial machines need some […]
What is a VFD (Variable Frequency Drive)? Technical Summary
What is a VFD? Variable-frequency drives, or VFDs, are a means of controlling the speed of an ac motor, typically an ac induction motor. It does so by varying the frequency of the power source. VFDs operate by switching their output devices, which can be transistors, IGBTs, or thyristors, on and off. VFDs can be […]
