Not really a question. I mentioned on the RFL fourm that I was thinking of getting the MY1016B2J1 motor from you this is the reply.
Don't trust the chinese spec sheet for those motors. No load rpm is 3320 rpm and 302W at 2610rpm. The sheet says that is the maximum power, but if you play with the numbers the power actually keeps climbing to a maximum of about 550W at 1500rpm. I've used one of these motors as well as an EV warrior in my axe robot and if powered by a single 24V GP3300 pack they end up inflicting that same sort of proformace and impacts. Plus they are cheaper, easier to mount and come with sprockets (well they do here in Australia). And they are sweet drive train motors too, I've seen lightweights drive up the walls with them.

Hello Tony,
We have been working with the Chinese for over 4 months to bring a wide range of the Unite motors to the UK. Technical specs can be quite difficult to get but we are nearly there. I have no reason to doubt the specs provided. The MY1016 B2J1 has a rated output of 280W at 2750 rpm with a no load speed of 3400 rpm. The rated rpm has a tolerance of typically +/- 5% and is quoted as being in the range of 2650 to 2900 rpm. I do not have a figure for max power.
It's good to hear other combat robot users are having success with these motors. Thank you for your order BTW, the shipment arrived from China today and it will take us a few days to unpack and check the contents.
Regards

Hi Paul
Just thought I would let you know how the motor MY1016B2J1 is performing. It is now fitted to the axe on our new featherweight DragonMaster. well I am impressed, on the first test of the axe it went straight through the hut floor and i had to get a crow bar out to get the axe head out of the floor. Plenty of power the gear reduction is 9-1.
Regards Tony. |

Hi Tony,
Thanks for letting us know, how feathers have developed from the 'old days'. If you have a video clip, I would certainly like to see it. I have also been thinking about an electric axe for the Zeobot, did you use a flywheel and clutch?

Hi Technobots,
I'm looking at purchasing a few of the following motor: 24V 280W MY1016B2J1 1470-020
Question 1: the toothed belt pulley it comes with - is it standard 5mm pitch for 15mm wide belts, and how many teeth does it have.
Question 2: would a quantity discount be available on this item for 10-15off.
Many thanks in advance for any help you can offer.

Hi Paul
Using a 2 stage reduction for the axe. First stage Mod 1 spur gears. Second stage chain drive. The axe is conttroled by a 15amp Electronise controller but with a 20 amp fuse fitted. Tested the axe stalled motor for 5 seconds the fuse did not blow the controller got slightly warm but that was it. Will probably get a 30amp with external relays later. Will be putting a video this weekend on my web site. Pics up on site now www.teamdragon.org.uk
under DragonMaster.

Paul,
Re 24V, 280W and 300W motors 1470-020 and 1470-024. What type of bearing is used at the output shaft? If plain, are ball races available? If so what part number to order 6 motors?
Application is miniature railway traction.

Allan,
We have no data to advise bearing type but we are 99% sure they are ball raced. Their starting voltage and current is very low and they spin very easily. The only motor we have that has a plain bearing is our 12V 150W Feather Gold motor that takes 5A just to spin off load. These 280W motors take a little over 1A at just over 1.5V.
Regards
Paul |
