Axial Flux
- Dual rotor 500W motor with controller. Best starting point for a motor. - [1]
- Most complete plans
- has 8 kW version as well
- Late 2018, TU Delft students on axial flux coreless - [2]
- John Reimers - early 2019 - McMaster U grad student - [3]
- French student project - no plans - [4]
- 100W, about 1 in lb torque - 7000 RPM - so 70 RPM geardown gets you 100 in lb. Comparable to current motors.
- 260g
- Not bad.
Axial with HalBach Array
Radial Flux
- Thingiverse - [5]
- Generator - https://www.thingiverse.com/thing:2635188
Halbach PMDC
- MakeSEA 600W motor - [6]. MakeSEA 40 and 90W - 0.06 peak Nm torque - about 70% efficiency. MakeSEA 60W -[7]
- Testing on an ultralight aircraft with 600W motor - [8]
- French project - radial motor - .14 Nm torque - 100W - [9]
- Small Halbach array generator - 7W per 1000 rpm - [10]
PMDC
- Great scott - [11]
Linear
- Model steam engine - Solenoid Model Steam Engine
Simple BLDC Outrunner
- Including Howto - [12]
- Inrunner BLDC with embedded 3D printing from the WM Keck Center for 3D Innovation - [13]
PCB Motor
- Circuit mill + 3DP - axial flux - [14]. 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. [15]
- Isn't this a ducted fan, not a pule, turbo, or ram jet etc?
Alternator - Axial
- Decent at low speed - [16]
