3D Printed Electric Motor

Examples

Halbach PMDC

• MakeSEA 600W motor - [1]. MakeSEA 40 and 90W - 0.06 peak Nm torque - about 70% efficiency. MakeSEA 60W -[2]

• Testing on an ultralight aircraft with 600W motor - [3]

• French project - radial motor - .14 Nm torque - 100W - [4]
• Small Halbach array generator - 7W per 1000 rpm - [5]

PMDC

• Great scott - [6]

Linear

• Model steam engine - Solenoid Model Steam Engine

Double Sided Axial Flux

• Can be as fast as you pulse it - [7]

• 100W, about 1 in lb torque - 7000 RPM - so 70 RPM gets you 100 in lb. Comparable to current motors.
• 260g
• Not bad.

Simple BLDC Outrunner

• Including Howto - [8]
• Inrunner BLDC with embedded 3D printing from the WM Keck Center for 3D Innovation - [9]

PCB Motor

• Circuit mill + 3DP - axial flux - [10]. By Carl Bugeja

3 Phase BLDC Simple Jet Motor

• Magnets + coils. Doea lack of a magnetic core make it very inefficient, or can this do well upon geardown? High speed geardown is not easy, though. [11]
