Re: Brendon_m Moke

So my plan I'd to weld a coupling to that from the clutch side and mount the motor where the clutch was. Exactly like most other installs. Doesn't the crankshaft act as the bearing support for the drive gear/spline piece that passes through the seal in the case? There would be a lot of pressure try...

Re: Aust. Auto Aftermarket article on Batteries and EV's

The fact CATL are now the biggest EV battery producer in the world must mean there will be a lot of their batteries hitting the wrecked vehicle market soon, so maybe another source of cheaper battery packs for DIY EV builds and maybe the Chinese EV's will start to appear in Australia as the half cut...

Re: "Fuel" Cost for Novated Leaving

Good question for a first post Jason, I hope you get an answer soon so I'll know as well. Often wondered about tax fuel cost claims when it comes to EV use, we have a 2008 Prius that is hybrid drive and I'd like to upgrade it to plug in electric and as it is a business use vehicle the full costs sho...

Re: The need for blocking diodes in a battery charging solar array?

Re: The need for blocking diodes in a battery charging solar array?

The problem is not shaded panels, the problem is a solar array with no where to feed its generated current so this generated current at what ever voltage it reaches short of absolute open circuit voltage finds weak spots within the panels in the array. A fuse will not protect the panel from being ex...

Re: The need for blocking diodes in a battery charging solar array?

The first knowledge of a problem was the RV owner calling to say the battery wasn't charging as well as it did before on solar only. I would say the panel failure was a cascading affair with the weakest failing first and the strongest being the only survivors. On 2 systems where the panels failed a ...

Re: What motors will I require for a constant 120kW equivelant output?

Did you buy it from Ben? I think that was the AFM140. If it's the 4-turn motor you can run it on a bus up to 800 V DC. If it's the 3-turn motor, you can probably use a 700 V bus but no need for field weakening. It will be fast enough. Yes, this was part of the package I bought from Ben, along with ...

Re: What motors will I require for a constant 120kW equivelant output?

You won't want the motor to turn for no good reason, and the stator is cooled from behind so there's no cooling benefits to having it turn over. The motor windings will tolerate being at 130'C but you don't want to be there for very long. Make sure the radiator is sufficiently sized to shed the hea...

Hmm that's like about a 75kW 4-pole induction motor. 75kW 1,500RPM 120kW 2,400RPM 200kW 4,000RPM (assuming voltage high enough) If you ran the rewind so the voltage peaks out at 2,400RPM (~250VAC) would be about right. You could still reach 200kW+ at 2,400RPM but still run at higher RPM with reduce...

Thanks Chris. I wonder how long it could deliver the 120kW before problems started to occur and would a temp sensor in the coolant outlet be a good indicator?
