What is the Difference between Soft Starter and VFD?
The main difference between VFD and Soft Starter is that a VFD can increase or decrease the speed of the motor, while a soft starter only controls the smooth start and stop
Electrical Drives
Controlling Multiple Motors with one VFD
In many applications, we use a single VFD for multiple motors. In this method, more than one motor is connected to a single VFD drive.
Why Insulated Bearing is used for VFD driven Motor?
The insulated bearing for the motor is used to prevent the circulating current through the motor bearing. The circulating bearing current can damage the bearing.
DC Injection Braking of Induction Motor
DC Injection Braking of Induction Motor is an effective method for stopping motors quickly without mechanical components. It involves applying DC to the stator windings
Dynamic Braking in Variable Frequency Drives(VFD)
Dynamic Braking in VFD is a technique used to safely stop high-inertia loads by dissipating excess energy through braking resistors. Variable Frequency Drives (VFDs) are
IR Compensation in DC Drive
IR compensation is an essential feature in DC drives and VFD to ensure speed regulation, especially when tachometer feedback is unavailable. The following sections explain
