Question for Castle Reps or anyone who may know ?

[Bondonutz]

Castle is not excepting calls till Monday.

I have a older model MMM with bullet receptacles for the motor wires and want to wire up a 540 2 pole 10.5T sensored motor to it. Can this be done and run unsensored, if so which ports are designated A,B,C ??

THX,
J.

In sensorless mode, the A, B, and C wire designation is not important. Make your connections and activate the motor - if it turns the wrong way, swap any two wires and you're done.

As far as I know (and thats not much) all sensored motors can be run unsensored. Wire it up like any other motor, if it runs backwards just swap 2 wires around.

Edit: Mike beat me to it lol

[Bondonutz]

A buddy of mine smoked his MMP hooking up a sensored motor planning to run it unsensored so I was concerned doing the same.

Thanks Mike & Josh.

That smoking might of come from the startup cogging that you get from running slotted 2 pole motors.

IIRC, you can also select motor direction in CastleLink if you can't/don't want to swap wires...

and 2 or 4 pole

I do know I tried to run a novak motor from a HVmaxx setup on sensorless cotroller.
I did not have such good luck.
It ran but never smooth like it should.
Look up the motor and see if it says anything about sensorless.
I didn't smoke nothing but had cogging issues.

You will always have that startup cogging with those roar type motors trying to run sensorless. You can reduce that effect with gearing and startup power, but to me that just sucks as you can't get the full potential out of the motor. The 4 pole sensored motors work just fine in sensorless.

Sorry, not on the mamba's, I just checked mine

My apologies, I must have been thinking of my medusa program.

Tech guy I knew a long time ago said "Generalizations are never true."

I think it depends on the motor. I ran a Novak 8.5 (2 pole slotted) motor on an original Castle sidewinder for a while in a 2WD off-road truck and I thought it ran better than when I was using it with a sensored ESC.

What rotor where you using in that 8.5T motor?

I got around the cogging with a 12.5mm rotor and some more voltage with my 2.5T motors. The LRP with 14mm rotor is a hard one to start up in sensorless.

IIRC, standard 12.3 rotor.
