Study Notes

Braking Methods

Regenerative braking is a method used with wound rotor induction motor, but not with SCIM.
Plugging braking and dynamic braking are other braking methods.

Conditions for Regenerative Braking

Regenerative braking can be obtained only above synchronous speed.

Comparison of CSI and VSI

CSI is less reliable than VSI.

Other Key Points

Dynamic braking is a method, but not the same as regenerative braking.
There are specific conditions for using regenerative braking.
CSI and VSI have different reliability levels.
