Re: Revolt RV-series motor review and comparisons

On my Neu 8057 the shaft is attached to the bell with 6xM5 bolts and inherently glued with loctite: neu1.jpg neu2.jpg Yeah!!! That will hold up! Since I've been modding these Revolt motors in a similar fashion...nice to know I was doing something right. I'll have a look at Neu motors. Where did you...

Re: Revolt RV-series motor review and comparisons

As already mentiond, it is the Loctite 648 which should be used for that. The feather key should be up to the task for what the motor is capeable to deliver to the shaft, but i agree that it is a little bit undersized. btw: it is the torque which will shear off the key and not the power! :wink: You...

Re: Revolt RV-series motor review and comparisons

Super Loctite was sort of joke. They do make many different flavors though. I used some green "wicking grade" stuff that was almost like welding the parts together. I don't remember the number. It was more like super glue. Yes, any kind of anaerobic locking fluid doesn't work well if there is much ...

Re: Revolt RV-series motor review and comparisons

Any pictures of failed keyways? One thing that would help is to glue the connection together with super Loctite or something that will prevent any movement between parts. Its when you get a little free play things start to hammer and you get deformation. Just high power isn't the real problem but s...

Re: Epic 7kw+ 12 fet controller...or there abouts :)

So from your extensive experience with modding the controller where do you see the weakest link to be? I'm considering adding a little more solder to the shunt for 55-60A on mine... Im thinking the 14-16awg phase wires going into the motor that are only about 6" long won't like those phase amps... ...

Re: Revolt RV-100 series motors

In conversing with Revolt, they won't tell me anything other than what they post on their web site. I think they really dislike me scrutinizing their motors, but won't say anything. You'd think they would want to brag about their motors...at least the Pro and E...nothing. They get annoyed when I te...

Re: E-Bike XB-502 conversion project

I went for a test ride now that it's all back together. Everything is working well again. I should try switching the motor to delta and dropping a tooth or 2 on the motor sprocket. This may get me the acceleration I want and still retain the top speed. I'll make a motor bracket in the next few days ...

Revolt RV-100 series motors

This ought to make a few people happy... I took apart all 3 RV-100 series motors so I could do comparison images. Bell bottoms. https://i1055.photobucket.com/albums/s515/rkenders/EV%20Stuff/Brushless%20motors/Revolt%20Motors/RV-100%20series%20bell%20bottoms.jpg Left to right: RV-100-Regular, RV-100-...

Re: Revolt RV-series motor review and comparisons

[off topic comments removed by moderator] Last night I replaced the shielded bearings in the E with sealed ones. I'll be adding SMD halls between the stator teeth like I did to both Regular motors. Hall placement isn't very consistent. As can be seen the halls don't overlap the magnets. It's not rea...

Re: Revolt RV-series motor review and comparisons

From the looks the stator seems to be on another level in comparison to the previous revolt motors. Thank you for the pics! Why they decided to place the hall sensors beside the stator hanging free, and with a large gap to the magnets is kinda strange and also the thing with the large resistors loo...

Revolt RV-100E

With the motor base on it, I can now turn the motor. The much stronger magnets definitely make the cogging effect a lot stronger. The bell bottom came off quite easily. Remove 6 screws and with very little prying, the bottom came right off the armature. The bell bottom and top are CNC milled quite n...

Revolt RV-100E

I got to mess with the RV-100E a little and made a paper template for the bolt pattern for a base. Now that the base is made, I can pull the motor apart. I made 3 blanks so one of those got used today to make a base for the E. Since I didn't know for sure if the paper bolt pattern transfer would be ...

Re: Revolt RV-series motor review and comparisons

I'll be using 219 chain and sprockets. The shaft on the RV-120 is 15mm. I have several of these shaft adapters already made that have a 3/4" OD with a keyway. The ID's are 10mm or 12mm or solid. https://i1055.photobucket.com/albums/s515/rkenders/EV%20Stuff/Brushless%20motors/Motor%20shaft%20to%20spr...

More on the RV-120-regular motor... I bought a 3 jaw chuck so I can hold round objects. I could have gone with a smaller chuck, but the theory is that I can hold large stuff now. I was limited to whatever could fit in the jaws of the cross vice or across the face of the rotary table, Now by holding ...

Re: "GT Asteroid" aka Currie Overhaul & Questions

I like the idea, but it will have issues. The chain will pull inline with those slots and pull over the motor slowly. No amount of cranking down the screws will hold it in place. You need your "under tension" point to be more or less 90 degrees from the direction of force. Your plan can work, but ro...

Looking at the voltages on the DC-DC board, I have batt-, but no batt+ voltage. I'll figure it out...just wierd that it's not there after the initial large w...

So...hijacking my own thread... Just my preference and opinion, but Chinese LEDs are pretty lame by comparison to legit CREE's. Can you say "64oz big gulp vs a sippy cup"?

Kelly KBS7221E upgrade

I've had this trapezoidal Kelly controller for several years. It's also pretty strong...something like 10kw. It's seen about 6000 miles of use and has never given me trouble. It has one oddity with regen where if you have it set too high, the controller will disable at random when coasting down hill...
