IGBT (Insulated Gate Bipolar Transistor) 1 Differences Between MOSFET and IGBT
... The conductivity of the resistor on the base branch is increased (modulated) when the IGBT is turned-on. This way, the greater part of the load current is flowing over the base branch.

Stepper motor
A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
