Servo Drive parts diagram: 1 bare PCB, 2 IGBT power module, 3 gate driver board, 4 DC-link capacitor. 91 parts in 4 top-level items. — Servo Drive parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Bare PCB	1×	Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
2	IGBT Power Module	1×	Insulated-gate bipolar transistor module: a half-bridge or six-pack of power switches on one substrate that forms the switching stage of an inverter or drive.
3	Gate Driver Board 3 parts	1×	Circuit board carrying the gate driver ICs, isolation, and protection that switch the power modules of an inverter or servo drive.
4	DC-Link Capacitor	2×	Large film or electrolytic capacitor across the DC bus of an inverter or converter that smooths voltage ripple and supplies switching current.
