Motor on Ebay

Odd looking motor on Ebay

http://www.ebay.co.uk/itm/24volt-1-2.../221983092702?

Do you think this would be clockwise only, or are they just stating the rotation for the given polarity?

Thanks

Edit: seems its a "Brake Pump Motor, 24v, 14 winding"

Its very likely to run in both directions but it might be timed to run faster in the clockwise direction. I don't see any output shaft in the photos, be careful that you don't get some useless little stub shaft.

that inset shaft with the channel across it is the motor shaft.

I swear that last photo wasn't there when I looked! It would be a complete PITA to couple that to a wheel.

I've had a shaft like that on my Roger Plant motors (not the Littons). I coupled the motor to a heavy angle grinder gearset and transfer that to a chain and sprocket to the wheel. This setup worked great in RCC2 for years.

Thanks all, I will probably give it a miss, was considering it for a weapon. Now to dig around in the garage for my old GPA750s

Those could be worth a mint these days. Sell em and buy a mini magmotor!

I thought you were looking for drive motors; the eBay motor or a short Mag motor is WAY underpowered for today's heavyweight weapons. Most featherweight spinners are using motors between 1.5 and 4KW.

The low end of the spinners in the feather class use at least 700W motors. And those are "historical" machines.

For a heavy, look at 24V 2kw and overvolt them to, 36V, then those are 4.5 kw on paper, and hot, if not melting after a fight.

Better yet, use one of the new48V fan cooled long mag motors - their peak power is now 8.5 KW . They are only slightly more expensive than the original A28-400 motors that put out 3.3 KW, making them quite a bargain (compared to all other over-priced motors).

Thanks, I have been fiddling with humanoid robots for too long, Watched Battlebots last night.... going to need a bigger spanner.

Searching around the forums for information on motors and controllers comes up with lots of information, but tends to be buried deep in the posts. Would be good to have a parts and suppliers page somewhere with all the common items people have used, and where to get them.

I have my 2 new Bosch GPA750s (bought in 2002 from Ellis) and a couple of 4QD NCC-70 controllers, but really need to get some new kit as spares for these would be too difficult to get hold of.

[maddox10]

Sell these to teams that are using the parts, and go for a more modern setup.

But the esc's will be difficult to sell.

I feel partial to Iskra motors.
