Motor current draw findings...

[neurokinetik]

So I just put together a little rig that connects up my stock battery holders directly to the motor with the ammeter in series. On a fully charged set of NiMH batteries, here's what I found:

(These are unloaded numbers, BTW)

Stock motors
Stage 1 motors: 0.26A - 0.35A
Stage 2 motors: 0.45A - 0.53A

Spin Brush motor: 0.28A

Tamiya Plasma Dash: 1.7 - 1.8A

Team Orion Elite stock motor for Micro RS4 (180 type motor): 0.21A

GPM MH038 Hi Speed 35T modified motor (180 type): 0.27A

(Need to borrow a stock X-Speed to test)

Experimental and modified motors
Spin brush armature and can, stage 1 magnets, endbell, and brushes: 0.37A

Stage 1 with spin brush magnets, timing advance, and BB endbell: 0.18A

MiniZ Racer Z130-A-BB armature with timing advance in stage 1 can with spin brush magnets: 0.40A

Stage 2 with spin brush magnets and timing advance: 0.60A

Stage 2 reduced to 44 turns, timing advance, and Drac's Neo magnets in Auldey BB can: 0.70A

25 turn (28 Ga wire) armature in stage 2 can: 0.89A, but it pulled as high as 1.4A before it topped out.

Custom 35 turn (28 Ga wire) in Stage 2 can with timing advanced: 0.90A

Custom 35 turn (30 Ga wire) in Stage 1 can with timing advanced, and spin brush magnets: 0.70A

Custom 35 turn (28 Ga wire) ex-Plasma Dash armature in BB motor can, timing advance, thin Neo magnets: 0.58A

Custom 30 turn (26 Ga wire) 180 motor: 0.50A

Custom 2 x 21 turn (30 Ga), timing advance, spin brush magnets, ball bearing can: 1.7A
