Spindle Drive (VFD)

Assembly

Variable-frequency drive that sets each spindle speed and ramps the motor up against the cutting load. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.

Spindle Drive (VFD) parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat 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 Gate Driver IC 2× Integrated circuit that turns a logic-level control signal into the fast, high-current gate pulses needed to switch a MOSFET or IGBT.
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 Power Inductor 1× Wound magnetic component that stores energy in switching converters, smoothing current and filtering ripple.
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.
