My first motor

Hey all

Now this post isn’t about 25 years ago when I started rebuilding DC forklift motors but is about finally building a motor for myself.  So after all these years of building motors for other people I decided it was time to pimp myself up a motor.  Late last year before Battery Beach Burnout Shawn waggoner and Matt Graham from SEVO got to know each other a bit working on some colaborated projects.  Like I always do (I do alot of homework, lol) I went to there site and checked it.  they had a mini-chopper page but it was under construction.  Long story short is when I asked what they were running cost wise.  A few days later a mini-chopper shows up (now talk about making freinds, wink, wink, lmao!!)  I guess they were happy with the motors.  Well if they wanted to make me happy they did, but alas the frame sits bare.  Hell Wayland even gave me three batteries and I have the thottle.  So this leaves me with very little left to complete.  A few weeks ago I discovered a 12 volt armature with a nice keyed shaft and kind of built the motor around it.  This MLD style motors come with large comm bars so there’s not many in the comm.  Now they also use a small brush which spans only one bar at a time.  I converted it over to an Advance brush and holder and am commutating two bars at a time now.  I have no idea what this will do under load but she bench tested really nice.  Father Time uses one of these motors on the 72 volt drag bike he ran at Woodburn last year.  Now this 12 volt motor does a decent 1/4 mile but the take off was lacking, to top that off I wonder about the smaller OEM brush ability to commutate at these currents which is 5 times the voltage rating as a forklift motor at 1 hour duty cycle.  Now I’m only going to be pumping 36 maybe 48 volts into the chopper but it will be a good test bed to see how the motor will react to this modification.  Alot of the stall on the project is it’s been cold and wintery here and I’m from Sothern California and people who know me call me a lizard.  So now with warmer days coming and a new flashy motor all ready I’m hoping it won’t be long.  Of course I have the High Voltage Nationals to attend in May and have alot to do before then so I’m hoping sometime this summer I’ll be scooting along in silent bliss, that is unless the man pulls me over for being over a 1000 watts, lmao!!  Anyways thanks for letting me share a bit about my first EV project.  As far as documenting it I didn’t 8^ (  But I grab a couple pics and thought I’d post them for some filler material 8^ )  I’ve decided to put them in Jims Toy Box so take a look.
