Connections For Motors!

[Malakite]

Easy one this although I don't know the answer!

I would like to buy a pack of the round 'male' connectors that usually appear on the end of a motor that connect directly into the 'female' connectors found on the latest ESCs. I guess the packs will come with male and female which is fine, I just don'y know what they are called to order them!

Bullet connectors? or am i making that up? old tamiya guide book has them down as 'snap connector set part#50245'

[Blacque Jacque]

Tamiya Snap Connector Set 50245, yes they are also called bullet connectors.

they're the fellas.

Theres a shop on ebay "ExcelsiorBikes" that sells motorcycle bullet connectors.

They look almost identical to the tamiya ones.

Not sure whether you need these to restore a car or just want to easily change out motors but these connectors are poor at best they loosen over time and start to arc. I would recomend Deans or any of the other high quality connectors

BTW: The crimping tool that comes in that "snap connector set" is a complete waste of time. If you do plan on using those, I suggest you get a decent crimping tool...

Personally, I would only use these types of connectors on vintage cars that you want to keep as original as possible...

I was going to suggest Corallys as well but didn't want to confuse things further

Brilliant thanks as always

So what are Deans connectors then? What do they look like etc? Do they make a difference in terms of speed/battery life etc?

type in deans in ebay under the section radio control, i use deans on all my racers, oem ones on the shelfers

Whats the benefit of these though? Is it just convenience of a more secure connection?

Lightweight, Secure, Low resistance for High current...

Deans Ultra Plug (don't be fooled by cheap imitation deans "style"):

The male (gold) connector goes on the ESC & Charger. The female (silver) goes on the batteries. I always direct solder motors. Installing plugs costs more, looks ugly and increases resistance. Besides, it doesn't take long to heat up that soldering iron anyways.

Whatever you do, be sure you note which pin on the connector gets soldered to which lead (positive is marked with a "+"). Having a battery pack wired backwards is a quick way to end the life of a lot of ESCs. We found this out the hard way a couple weeks ago when a friend was lent a battery from someone who's equipment was all wired backwards. His ESC went up in smoke instantly!!!

yeah, i blew a charger by dropping an exposed deans connector still connected to the charger

Thats why I only buy chargers with fuses. I also make sure my chargers are unplugged till after I connect the battery and unplugged before I unconnect the battery.

I read some where in the Forum earlier that you need the help of a spider monkey just to unplug the the dean connectors. I think the it would be very costly just to have a monkey around for better electrical conduction and the monkey would be bored unless you RC every day.

My personal opinion is you are just kicking around not into racing than the regular Tamiya plug or bullet connects should be good enough but if you want nothing but the best and or into racing than dean plugs are the way to go but make sure the wirings can handle the current and are just enough length.

These ones work good between ESC and motor. 5mm Bullet Connector safe to 150A. There is a larger 6mm that is safe to 200A.

Never had a problem myself pulling deans apart. I use them on everything, ESC, Batteries, Charger, Motor. My brushed controller (hardly ever used anymore) I swap between cars and it makes it a lot easier having the motor unplug.

So presumably when we talk about the wiring being good enough for deans, I take it the original wiring that comes with the cars/motors/chargers/ESCs is good enough to handle a deans connection?

[TA-Mark]

The wires generally have the right Amp rating for the ESC, it's just the Tamiya plug when it becomes used/corroded that becomes a problem. Same with the standard bullet connectors for the motor wires. And only an issue on a car that is run, shelf queen has no need for Hi-Volt plugs.

Cut the Tamiya plug off, bare 5mm of wire by cutting off some of the insulator and solder to the poles of the deans. Shrink wrap, that comes with the deans, to help prevent a short at the backside of the deans.

Someone should do a tutorial on replacing Tamiya plugs with Deans, and the same for powerpoles so we can refer this question to it.
