Motor selection and motor installation questions

[Gimpalong]

Well, I went back and reinstalled the SHS motor. I substituted the spring from the old motor for the one in the SHS motor and it fit into the motor cage just fine. Gun cycles, but I'm going to need to take some time to adjust the motor height to get it right.

Seems a bit underpowered, honestly. I'm not sure if this is a result of the motor being adjusted too tightly (which I can change) or if my battery is just too small to provide the needed power. The battery is a 7.4 1000 mAh 20C. The battery definitely gets warm quite quickly.

SHS' have a tendency to get warm, in my opinion, quicker than other torque motors. That's been at least my experience (to the degree that you have to have gloves if you're in a decently long firefight).

I believe the SHS motors have Neo magnets, which take better usage of the battery they are with and don't "cap" out. So I'd have to assume that bumping up the an 11.1v would show you better results.

You also have to remember it's a high-torque motor, so it's meant for bigger springs and a quicker response than BPS. If you wanted something more noticeable of a difference, you should have went with the Lonex A1 Motor.

Higher torque motors reach maximum speed quicker than high speed motors and hence give faster shots in semi in most cases. He isn't looking for high ROF and the SHS motor should put him right were he wants with the battery he is using. Also, 16 TPA isn't really that high torque anyways compared to other motors out there such as the JG blue. The warming up in older SHS motors has apparently been fixed in the new ones.

[Gimpalong]

Yup, Ctres is correct. I'm looking for snappy performance in semi-auto. That said, I've been experiencing some binding in semi-auto. That's why I mentioned that I need to take some time to adjust the motor height because I think it's too high (tight) at this point.

That Lonex A1 that you linked to above actually looks exactly the same as the SHS aside from the sticker. The can, spring and red base plate look exactly the same oddly enough.

Thanks for the responses guys, I'll keep playing with it. I might be a bit jaded by my Polarstar and am expecting too much.

The battery you are running is also a pretty low discharge and is probably starving the motor a bit. SHS are slight power hogs and having more than 20 A to use would help.

I didnt read through all of the thread either, but if you didnt reshim the gearbox properly from bevel to pinion then you dont have proper motor alignment and is probably another contributing factor to sub-expected performance.

I'm assuming that's 20C continuous. The burst rating should be higher, no?

Right, the burst rating is higher, but a lot of people are running 40+ C LiPos in setups nowadays. The motor will only draw what it needs and no more, so it doesnt hurt to have more than you need.

Hi guys,

I went back and adjusted the motor height. I was playing around with the gun and noticed a serious performance difference when I used my one Intellect based 7.4v 20C lipo versus my three cheaper 7.4v 20c lipos. It's entirely possibly that my cheaper batteries are labeled as 20C, but aren't actually. With the intellect cells, I get a nice crispy trigger response and a nice rate of fire. With the non-intellect cells the gun feels very sluggish.

Thanks for all the help, guys. I think if I pick up a 30C or 40C 7.4 lipo things will be sorted.

I highly recommend that you tune the gun up as well if you havent already. Proper shimming, AoE, swiss cheesing, ect will also make a big difference, especially if you up your LiPo to run the motor at peak performance.

Glad to hear the problem is sorting itself out though!
