    New Dewalt brushless motor?

    So i went to dewalt's home page to find the closest service center to see if i could run over and pick up a 14.4v motor and saw that they have introduced a new drill with a brushless motor in it. I was wondering if that motor would be able to work in the summit.

    The website says that it is supposed to run 57% longer than their brushed motors and cooler. I am just curious if i should go ahead and get the 14.4v brushed motor or wait for this new brushless motor.

    I believe you will need a new speed control as well if you purchase a brushless motor.

    It's back to the old 1:1 saying, again....

    Get the 14.4 it is proven,it works
    With the evx 2 I have run mine hard for a long time still going strong. It's not a rocket engine but can be geared a bit more aggressively.a bit more speed ,yes
    but gobs of torque

    Correct. The EVX-2 will not run a brushless motor.

    What would be a good esc to get for it? I think I will get the brushed motor now and experiment with the brushless motor when it comes out later.

    You are then back to the brush less equation. The only speed controllers that are worth attaching to a brush less motor for a heavy summit is a remind rx8, castle mmm or mmp or one of those foreign esc.

    And unless that brush less dealt is waterproof, or is out of this world torquey then you would be better off just buying the complete brush less system.

    396505-21 sv. The "sv" seems to be optional - some places list it, some do not.

    theres about six different part numbers for the same/similar motor, the one that ksb51rl says is correct and probably the most advertised.
    There is basically two types, the Old type with 4 mounting lugs on the edge of the can, you don't want this.
    The New type with the flat end, this is what you want.

    All correct! Even Black and Decker (same company as Dewalt) has different numbers for the same part.

    The EVX2 WILL be able to control your brushed motor... not maybe it works. We all do it. It will NOT be able to control a BRUSHLESS motor.

    i have only seen schematic drawings for the black and decker and looks the same. I must of deleted the black and decker bit out am sure i had put that in too. I haven't seen the black and decker motor but the schematic drawings it looks to be the same motor. Maybe different winds/turns but the can itself looks to be the same.
    Black and decker is for the diy enthuisiast while dewalt is more professional trade.
    This might just be the better gearbox in the dewalt, compared to the black and decker. everything else the same. I'll have a look see if i can find it again, it has been a while.

    That makes me wonder if one is better then the other and is one is cheaper then the other.
    also who makes the motor. Basically cut the middle man out and order direct.
    I actually work for a company the is a dewalt service center so I've been quizzing my hand tool guy but haven't been able to get much out of him.

    I've tried to find the black and decker motor but haven't found one, I lost all my internet bookmarks a while back.
    The dewalt/ black and decker factory is maybe 40mile from where I live. They are quite secretive.
    I contacted dewalt and told them that my motor had been damged, then gave him the motor number, but when I looked online for a replacement, I could only find the part number giving above and asked would that motor be suitable for my drill and why are the numbers different.
    When they replied they said, its a revised part numbers and I should take the drill to the local service centre.
    I would guess that the last two digits are the motor timing number but they wouldn't say.
    Dewalt motors are quite inexpensive for what they are, and they're used successfully with the evx2.

    B&D 14.4V motor p/n = 579724-04 but I've only uncovered them in the UK or in NZ.
    I'm thinking it has to be the same motor as 396050-21.

    What I find really weird is I have fried so many B&D motors in my drills but have never smoked a dewalt drill motor. That just makes me think that the dewalt are better. Also a dewalt drill is almost 200 bucks vs. The Walmart 50 dollar drill.
    I appreciate everyone's research and I know i will be going dewalt powered real soon.

    you can just buy the motor for $30, from online robot shop, This is the new style.
    I think they last longer because of the gearboxes, dewalt is designed for all day use commercial. Black and decker is used in the home.

    Search the thread, there are several good "how to's" with photos. You will need to remove the pinion from the Dewalt. You must also slightly modify the mounting holes on the motor mounting bracket with a Dremel or small file(I used a file).

    I didn't even think of looking for a how-to thread. I'm not thinking straight today; I'm blaming the heat.

    Yes, that's a good one, but please don't spread it around. The canadians are enough of a problem as it is. (Zing!!! pav, j/k)
    If I ever feel the need to install a 396505-21SV, that is the tutorial I plan to consult.

    Thanks for the link that will help a lot when i go to swap but the motor. However, my wife's car died last night so i guess the dewalt upgrade is going to have to wait until her car is fixed.
