Linear PCB Motor

Just received the PCBs from OSH Park!

This is the 3d model of the slider for the first linear pcb motor prototype. This slider houses a 2x20mm diameter neodymium n52 magnet that is used to slide across the pcb by the coil's magnetic fields.

For this project i decided to used 5/5mil traces for the windings on 4-layers, adding to around 140 turns. This design choice makes the coils much bigger than the ones I used for my micro PCB motor (https://hackaday.io/project/39494-pcb-motor) which had 4/4mil traces and around 40 turns.

The bellow 26.7 x 258.2 mm 4-layer pcb with the 12 coils was designed. Thank you oshpark.com for supporting this project.

The last few weeks I've been thinking about designing a very thin low-torque linear actuator that using pcb trace windings similar my pcb motor project (https://hackaday.io/project/39494-pcb-motor).

My idea is to have 12 vertical coils and alternate their magnetic field and actuate a magnetic rig and slide across the pcb.
