Motor Controller parts and their functions
6 top-level parts · 17 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 | Microcontroller | 1× | Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware. |
| 3 | Power MOSFET | 6× | Power MOSFET: a voltage-controlled semiconductor switch that turns high currents on and off at high speed in converters and motor drives. |
| 4 | Gate Driver IC | 1× | Integrated circuit that turns a logic-level control signal into the fast, high-current gate pulses needed to switch a MOSFET or IGBT. |
| 5 | Current Sensor | 3× | Hall-effect or shunt-based sensor that measures the current in a conductor and reports it to the controller. |
| 6 | Connector | 5× | Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering. |
