Servo Drive Amplifier parts and their functions
5 top-level parts · 135 parts in total · full bill of materials below
| # | 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 2 parts | 1× | |
| 4 | DC Bus Capacitor | 2× | |
| 5 | SMD Passive (R/C/L) | 90× | Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board. |
