I don't see any specs for the 9015 FP motors.

Seconded w/r/t the Johnson 9015, and also, does anyone know for sure if the new Keyang is the same as the old, apart from the different connector housing, spline and shaft?

are you thinking of the keyang or the taigene?

as I recall, the taigene looks similiar the the keyand somewhat...

thanks, vivek

are you thinking of the keyang or the taigene?

as I recall, the taigene looks similiar the the keyand somewhat...I already compared the current Tiagene (16640238) with an old one that was lying around; they did not share the same model number, so I assume the current Tiagene is a different model (however, I don't know which of the old Tiagenes this was, so it's possible that this motor was issued in the past).

As for the Keyang, there three models which are legal this year: 16627960 and 16627961, which are equivalent to last year's LH and RH Keyangs, and the new Keyang, 16631023. You're allowed one of either 16627960 or 16627961, and one 16630123. I'm wondering if they're internally identical (and therefore we can use the same data as before for design).

Can anyone verify the specs of the taigene are accurate?

Where are you getting the Taigene specs from? I can't find anything on that or this new 9015 FP. Does anybody have a dyno lying around that they could test these motors on?

who has the motor specs??

fp 9015
the 2 small motors
rs 540
rs 550

I'm assuming the mini-bike motor listed in the good tips page is a mis-print.

Thanks in advance.

I was just in contact with a representative from F-P regarding the 00968-9015, and he says FIRST has been given the motor curves already. I'll ask FIRST if they're planning to release those now. If not, I will check with him tomorrow to see if he wouldn't mind sending it directly to me, so that I can post it here.

Travis Schuh

Is the 00968-9015 fisher price motor similar to previous motors? I know that the fisher price motors change from year to year, but would it be reasonable to look at the specs from previous year's motors to get a rough idea of whether the fisher price motors will be strong enough?

Thanks,
Travis

Am I missing something or does the Taigene's specsheet only give dimensions, and not performance specs?

Paul Copioli

The Fisher-Price specifications on the FIRST website are consistent with the specifications I received from Johnson Electric.

Use the specifications on the FIRST website as they are accurate.

If I remember correctly, Johnson Electric's stats from last year contained more info than those issued by FIRST. Is this true this year? If so, can you please post the Johnson spec sheet?

do we know exactly what motors we have?

there are several 540s and 550......the rs385 isn't listed for our rpm.

Is the FP gearbox still 124:1 as in JVN's spreadsheet?

reflion

Anybody know the torque of the Taigene motor? It's not listed on the specs FIRST provided, and we need to know if its a motor that we can use for our task.

Gary,

I had some students verify the Fisher Price gearbox this weekend. They calculated it to be 125:1. A few miscounted gears and it could easily be 124:1, so I would confirm JVN's numbers to be correct.

Thanks Ben - good to know at least one thing that looks the same stayed the same. If I threw all the FP motors (or window motors, or van door motors) we have on a table and stood back a few feet, I'd be hard pressed to remember which ones are allowable. Sounds like a good game to play with the students.

I'm very confused about the two small RS 385PH-18110 motors that were provided in the kit this year. I found this datasheet from google:

http://www.google.com/url?sa=t&ct=res&cd=1&url=http%3A%2F%2Fwww.e-star.tw%2Fdata%2FPIC%2F%25E6%25A9%259F%25E9%259B%2 5BB%25E6%2595%25B4%25E5%2590%2588%2FDataSheets%2FM otors%2FBrushed%2520DC%2520Motor%2FRS-385PH-18110%25205-9V.pdf&ei=nTKUR_qMJYOsgQS-4_i5DQ&usg=AFQjCNHzFch6t6i63Oy34XswGpyLLG95rg&sig2=xMLHzqChHyVREKbzJpbsIw

which says it is a 5V motor.

I also saw that Banebots sells the RS 385 motor (though this might not be exactly the same model), and says the operating voltage is 3v - 9v and the nominal voltage was 7.2v.

Aren't all the motors supposed to be 12V motors? If not, how are we supposed to use them?:ahh:
Richard,

I too found that spec sheet, but I don't think it's anywhere close to correct. I base this on two web pages:
Mabuchi RS-385PH Specs (http://www.mabuchi-motor.co.jp/cgi-bin/catalog/e_catalog.cgi?CAT_ID=rs_385ph)
Mabuchi Motor Designations (http://www.mabuchi-motor.co.jp/en_US/technic/t_0302.html)

The specs page lists similar motors as ~24V nominal and has all the relevant specs. While it doesn't list our particular motor, decoding the model number using their motor designation page reveals that our motor is very similar to the -17120 model, but with increased armature wire diameter and, consequently, decreased armature windings. You obviously can't directly derive the specs for our motor from this info, but I'm confident you could use the -17120 specs as conservative numbers. I'm less confident that you could just take the difference of the -16140 and -17120 and add them to the -17120 and get decent numbers. Somewhere in-between these values is probably a reasonable guess without calling Mabuchi.

I have an old Fisher Price FP801-005 12V motor here. Is it a legal motor to use on our robot this year? I could only find a FR801-001 in the kit of parts checklist.

The part number doesn't match. Not legal even as a spare.
<R34> Teams may replace lost or damaged Kit Of Parts COMPONENTS only with identical COMPONENTS of the same material, dimensions, treatment, and/or part number.[quote]And even more tellingly (addressing this exact situation) here:[quote]<R58> Motors, pumps, and, Robot Controllers from previous robots shall not be used in addition to those provided in the 2008 Kit Of Parts. They may be used as direct one-to-one SPARE PARTS for those provided if the provided part fails or is damaged. They can only be used if
they are identical to the part being replaced.
 Note that the Fisher-Price motor found in the 2008 Kit Of Parts (Part number 00968-9015) is different from the Fisher-Price motors used in most previous FIRST competitions. Only the Fisher-Price 00968-9015 motor may be used as a SPARE PART for the Fisher-Price motors provided in the 2008 Kit Of Parts. Prototyping, maybe. But definitely not competition.

Team 2108 counted the teeth and came up with 123:1 and 125:1. As fine as the teeth are, it is easy to miss or double up on a few. We are assuming it is the same 124:1 published a while back. Plus or minus less than 1% is close enough for us!

Anybody know the torque of the Taigene motor? It's not listed on the specs FIRST provided, and we need to know if its a motor that we can use for our task.I haven't found actual specs on the the Taigene motor, but we have determined that it is REALLY WIMPY compared to a similar-looking one we have, probably from 2005. Our very scientific tests involved connecting the two motors to a battery in both directions and observing how much the motors "jump" from torque reaction. The old one jumps a lot more. Our second test was of the "don't try this at home" variety. A person held the motor in one hand and an adjustable wrench on the output shaft in the other hand while a second person connected the motor wires to a battery. The old motor had a lot more torque. The motors have different worm and ring gear designs, and they also have different "winds."

Download JVN's 2008 Design Calculator. (http://www.chiefdelphi.com/media/papers/2059) All motor specs are on there under the specs tab.

John points out that the specs have either been experimentally determined, or taken from the manufacturer.

I have yet to find specs of all these motors on the FIRST site.

Beware, at least some of the data on John's calculator are NOT for 2008! We just ran bench tests on the new Taigene Van Door motor (see attached), we will have the complete data for this motor and others available on the first.wpi.edu site very soon. The condensed data for the new Van Door is as follows (all corrected to 12.0V input): Free running--48 rpm/1.2 Amps, Stall--360 in-lbs/24.2 Amps. Max power: 53W. So it is about 20% less powerful than the last Van Door we were supplied.

I see these specs posted by teams about the Taigene Van Door Motor the what FIRST has posted on its website. My question is will FIRST ever post official performance specs about the Taigene Motor?

I wouldn't consider the "Jump" as an accurate method of torque testing

Kit Gerhart

I wouldn't consider the "Jump" as an accurate method of torque testingThe "jump" should be a good indicator if the mass of the armatures of both motors is the same, but I don't know for sure that it is. The "wrench on the shaft" test is a sure indicator of a difference, though.

The pinion on the motor should be 32 pitch. I think this year's is 19 tooth, but you can verify that by counting the teeth.

Ok, I'm really confused and really tired. My team needs to use the 16627960 Motor and the 16631023 Motor TOGETHER. Meaning we need to know if they run with the same specs I guess. Would it work having them oh lets say on opposite sides of the same shaft running to flip it up? For us if they don't run exactly the same it will destroy itself (trust me we know.) Anyway, I've been working to try to figure this out for several hours, any help would be really appriciated. I looked at Keyangs website AND FIRSTs official specs, Keyang isn't any help and FIRSTs specs are too small (and side ways on my screen) to read.

JVN spec for denso motor does not seem right.

JVN listed Stall torque for Nippon Denso motor of 9.2 N-m works out to 6.78 ft lbs.

In testing today, we measured ~12 lbs force on ~ 2 foot weightless arm today using a decent load cell. This is closer to 24 ft lbs so this is different from JVN spec by a factor of almost 4.

Does anyone have any test results on the Denso motor.
