Check out www.Holmeshobbies.com for availability of these beasts. Replacement brushes available now too.
I just got the final parts to the Cobalt Puller motors, and boy are these motors awesome! This is a departure from my normal style, these are good old BRUSHED motors fit to have the Holmes Hobbies name on them. They are for 2.2's, clods, and the 10T can be used in a super. The can is a bit longer than your standard motor, at around 2.5" long, so using them can provide a challenge with some link setups and clodbusters. It will bolt up inside a stock AX-10, a K2-3S(L) chassis, a stock Wheely King, and many more. It does not fit into a SW2 or SW3, GC-1, or similar narrow competition style chassis without careful tranny positioning or chassis modification. The diameter is 1.35", like a normal 540 motor. It mounts up to the standard 25mm bolt pattern, and uses 1/8" pinions like any standard motor. The best part is the LARGE 7 slot armature and large commutator. It allows a much higher commutation rate- giving better slow speed control and greater torque.
There are three winds available right now, very limited quantity. 10 turn, 7 turn, and 5 turn. Any of the winds can be crawled, as the 7 slot armature and large diameter commutator gives better control than the average motor. Some details from my website about the 10T motor:
Uses standard 1/8" pinions, and 25mm motor mount spacing- bolts up like a normal motor.
Strong Cobalt Samarium magnets
7 slot armature, 10 turn
6.5 ounces,
2.5" long, 1.35" diamter
5-12 volts
160*F max
Mamba Max highly recommended.
I have been crawling and testing these motors for a while now. At the last comp I ran the 10 turn with a 3 cell lipo in my 2.2. Slow speed control was second to none, and top wheelspeed was around 6-8 mph with a 84:1 geardown with mashers. That is tlt axles with an R2 tranny with 8 tooth pinion. Power was no problem of course, I could have gotten by with 6 cells nimh.
Pricing is $79.99. With increasing costs of high strength magnets and fewer manufacturers for brushed motors, this might be the cheapest that they come.
10t = 1700 rpm/volt (faster than a 35t handwound 540)
7t = 2300 rpm/volt
5t = 2800 rpm/volt
Any questions?
