Figure 1: Switched Reluctance Motor. Switched Reluctance Motor can be operated on DC as well on AC supply. It uses no brushes nor any permanent magnet. It is a specialized type variable reluctance stepper motor. It has less number of poles.
What is Plugging Braking? Connection Diagram & Working
Plugging is the simplest type of braking which involves re-connection of motor to supply in such a way that motor develops torque in opposite direction to the movement of rotor system, speed will decrease till zero speed is reached where mechanical brakes are applied and then it will accelerate in opposite direction. This method is

Maximum Power Transfer Theorem (DC & AC Circuits) – Statement, Derivation, Examples & Formula
“Maximum power transfer theorem states that the maximum power can be transferred from source (voltage source, current source) to the load only when the load resistance (RL) is equal to the internal resistance of the source (Ri)”. i.e, \[{{R}_{L}}={{R}_{i}}\]
