Sorry but is the lenguaje problem...
No problem. The IGBTs are "Insulated Gate Bipolar Transistors" which act as switches in the power stage. Generally you use six of them for a 3 phase inverter.
A snubber circuit is a circuit to minimize voltage spikes during switching events. Inductors (which is what your motor is) resist changes in current, and this resistance is manifest as voltage spikes. Snubbers use capacitors or diodes to limit these transient spikes.
