Re: washing machine 12 inch bldc outrunner

btw,i need to put 300v into it,100 volts for each of the 3 legs. company in korea stamped the drum as being tested with 310vdc,i would definately love to do the same. You can't put the same voltage into all legs at the same time; if you do there's no current flow and the motor doesn't move. You mus...

i dont think a commutator will work either,i need my contacts 30 degrees appart with a width (or duration) of 6 degrees.
It would work if you built it to do that.

Re: Lead current limit for different MOSFET packages?

But it's not as bad as it sounds, because the phase current is divided between the high and low side FETs. With 1 high and 1 low side that's 100A RMS output, Since they're in series, how does that work? :? Current is only distributed among parallel circuits. Current is always the same in series con...

Re: The Cycle Satiator, universal charger for the enthusiasts

So far, i was not able to charge the battery full ( 100% ) the process begins with preconfigured current ( say: 2 Amps ), but soon goes down to below 1A, and starts oscilating: (voltage and current - as well ) like 0.7, 0.5, 0.4, 0.2, 0.1A loop. with frequent `Pwr fault restart`in between.

Re: Poor Man's RV

I wonder how Justin set up that steering linkage. The hard part might be tapping the bolt into the front fork crown - could be easy, depending on the fork, just have no idea. Mine already had it, so I only needed a new rod with "rod end bearings" on either end, which was just an aluminum tube with ...

Re: washing machine 12 inch bldc outrunner

You mentinnoed i needed to use a contactor, imo a contactor is nothing more than a glorified relay,but in any case absolutely not suitable for my intended use of building a mechanical controller for this motor. No, I said "commutator", not "contactor". A mechanical controller is called a commutator...

Re: Hacking a Couple Stromers

I think that's what mine is, but it might be more like 140-145; I"d have to measure the fatbike fork I had it in to be sure. (can't measure the axle directly). I had to spread the fork to fit the motor in it.

EDIT: looks like it's actually about 160mm!

Re: MAC rear hub casset freehub replacment?

It's probably part of the side cover, specific to that model of the MAC. I doubt a regular bike hub freehub will fit it, based on various discussions about motors with freehubs over the years (sorry I couldn't find the specifc ones). I'd guess your best bet is to contact EM3EV (or maybe Grin Tech) a...

Re: BBSHD Voltage Problem Firmware Update & Instructions

As Fechter noted in the post just above yours, you can't read the controller's fw, due to protections in the MCU. (This is typical of every controller I've ever dealt with--no reading, only writing. Even the opensource and other self-developed controllers around the forum generally can't read back a...

However, I have´nt got any really noticeble braking.
Which motor is being used? If it's a geared hub, there won't be because of the freewheel (there are a couple of non-freewheeling geared hubs, but most of them do).

Re: Charging Sequence

I dunno. I'd always do it wall first then battery....but it depends on the charger design, I guess.

I suspect they just mistranslated the instructions, so maybe check with the manufacturer.

Common throttles are either potentiometer or hall sensor. Sounds like hte one you have is hall sensor, but the controller needs a pot type.

Re: EV Global upgrade

Since the EVG is 1500W I was looking at 3kw or 5kw. Why specifically are you targeting those wattages? If it's just because they're higher...well, they may not do what you want (or may be way more than you need). First you have to decide what this is going to be registered as--moped or motorcycle (...
