Variablefrequency drive Wikipedia

A variablefrequency drive is a device used in a drive system consisting of the following three main subsystems: AC motor, main drive controller assembly, and drive/operator interface.: 210–211 AC motor. The AC electric motor used in a VFD system is usually a threephase induction motor.Some types of singlephase motors or synchronous motors can be advantageous in some situations, but

DC injection braking Wikipedia

Appliions of DC injection braking. When power is disconnected from the motor, the rotor spins freely until friction slows it to a stop. Large rotors and loads with a high moment of inertia may take a significant amount of time to stop through inherent friction alone. To reduce downtime, or possibly as an emergency safety feature, DC injection braking can be used to quickly stop the rotor.

VFD for a spindle brake Practical Machinist

Apr 09, 2017 · There are many ways to do dynamic braking without a VFD. DC injection braking is used frequently. When the VFD does braking, the motor is a generator and the DC bus voltage rises. The deceleration time of the VFD is limited by the rise in DC bus voltage caused by braking. We have 3phase for our shop and I still put VFDs on a few mills
