Re: What is your favorite motor....
 

My favorite motor for our drives is no question the small cim. It was a great change from the old drill motors we had to use back in the day.

My other favorite motor is the Fisher Price. We use this motor to lift our platforms 12 inches this year. I was surprised when i found out they had enough power but they did.

Hands down, small CIM.

Re: What is your favorite motor....
 

If the question is drive, the answer is small CIM. A keen eye may note two large CIMs on our drivetrain this year. That's only because we're using one small CIM on the arm, since the BaneBots setup was far easier to work with than trying to figure out how to interface with the large CIM. If we were to switch out the arm CIM for some other motors for whatever reason, I'd definitely make the switch back as time allowed.

For arms, I much enjoyed the van door motor (it was on both of 1293's lifts during my tenure), and have been quite satisfied with the Denso motor thus far on 1618's arm (those black hubs are lovely). Looking at 1902's method of adapting the Globe motor down at UCF, however, has made me realize that perhaps I haven't given it a fair shake.

CIMs and FPs are on the top of my list. With the power they unleashed at Bayou, 2.5 horses sure did look like it helped at times, especially when we being pushed and for once could fight back.

Re: What is your favorite motor....
 

By far, the best motor in the in the kit is the small CIM. In most any application, it's a robust, powerful, and forgiving thing. It basically cannot be burned up, and for that reliability alone, it's better than the FP. It has equivalent power and efficiency, and though heavier, it's easier to design into gearboxes, abuse, and needs almost zero maintenance.

It's big little brother is even more forgiving, but it's weight and lower power negate this significantly.


But, a big thanks goes out to the old Van Door motor- that thing was robust and easy to design around, which saved us many times in the past.

That 400hp electric motor they use on the Epcot test track ride.

Re: What is your favorite motor....
 

the 700 hp engine in my 55 chevy is right up there too...but I fear we're getting off topic!

Re: What is your favorite motor....
 

I didn't hear anyone say FIRST KoP Motors or electric motors. [Although that's what they probably meant.]

Re: What is your favorite motor....
 

I'm gonna have to go with many others and say CIM. It has done wonders for our team haha.

Re: What is your favorite motor....
 

Small CIM tops the list, although I could be biased since I remember the horrors of tripping breakers with the Bosch drill motors. :yikes:

I would vote the Van Door as a close second, as they always seemed to be the perfect arm motor. It's too bad FIRST discontinued using them in the KoP. RIP little fella.

Re: What is your favorite motor....
 

well since no one said "FIRST motors"

Im gonna go with the A20A3, B18C5, B20A, H22A,K20A,F20B....... and oh ya the twin turbo supra motor

Re: What is your favorite motor....
 

depends on what they are used for.

LOVE the small cims, because first thing a robot needs to do before even thinking about anything else (figuratively speaking of course), the robot needs to be able to move. and move well it usually will, with small cims

big cims are awesome in their own way, not necessarily for use on a drivetrain or bot usually. they are heavy, hard to interface, and take up more space when one could usually use a small cim. however, when someone either new to or outside of FIRST sees these bad boys, the look on their face is priceless.

globe motors i like much. small, built in gearbox, durable. very good for most manipulators. much more could be said, but i wont say it here.

however, my opinion of FPs has somewhat gone down this year, considering the built in heat activated breaker that nobody knew about until we actually ripped one of these motors apart (by bandsaw, not by robot :ahh: ) words cannot describe how annoying this 'add-on' was.

btw, it really sucks that we cant use vandoors this year. they rock :(

Re: What is your favorite motor....
 

1. Globe Motor: these little things are indestructable, I tell you. It's a high quality gearbox on a small motor that is very compact. Very easy to design around.

2. Bosch Van Door Motor: that thing is powerful and has a long shaft to work around, unlike the smaller window motors.


(On a side note, 604 has accumulated several globe motors over the years and we can bring them to the Silicon Valley regional if anyone needs them.)

Re: What is your favorite motor....
 

I personally love the keying window motor; it’s robust and has plenty of power. I found that a #25 chain sprocket mates perfectly with its gear I had this connected to an arm. The window motor bent the screws holding the arm to the sprocket! I had to go and make hardened steel screws by heating and dipping them in oil.

I hate any bane bots transmission product. Our main 56mm gearbox failed (output plate) in the elimination matches. We couldn’t replace it in time………….

Re: What is your favorite motor....
 

i'd have to go with the small cims or the vandoor
believe it or not last year we actually managed to partially toast(horrible response time/power) 2 cims which basically lost us the galileo finals gah, but when we found out and switched them at iri we headed for the win. so small cims all the way
