    2 Honda IMA Inverter with Lebowski brain installed for sale

    No the IMA does not have a DCDC inside it. I was running 18V drill batteries with a DCDC step down to get to 12V and would just discharge the battery over time. I was using contactors out of a CMAX (if you need any contactors I have plenty).

    2 Honda IMA Inverter with Lebowski brain installed for sale

    Amber, Yeah, I forgot to put the pics of the wiring loom. Has a reset button, setup button. 12V power line (power on), Throttle input wires. The way you program it is with TTL thru the USB. I can take the housing off and power it up with 12V and you can see the LED's on the board. I...

    2 Honda IMA Inverter with Lebowski brain installed for sale

    I was running the IMA at about 160V for a while, then I bumped it up to 200V for a bit more speed and power :) The lebowski brain is AMAZING. The feild weakening is AMAZING!!!! With FW turned off the motor would accelerate like a rocket, and then hit a wall at about 5000RPM (due to the...

    Here are some pics of the inverters. The one with the bent fins is the one with the broken reverse. The one with the perfect fins is brand new from Kiwifait

    2 Honda IMA Inverter with Lebowski brain installed for sale

    I have 2 Honda IMA inverters that I was using on a project. I am not using them anymore. One is brand new from Kiwifait and the other one was used in my gocart project a few years ago. I was going to use in my new gocart, but switched over to volt inverter for higher voltage. One has the...

    Suzuki RF400E, now with Enertrac MHM602

    I had a kelly controller on a HSG motor, and the kelly heated up the HSG (IPM motor) FAST. I was running 160V. The power was OK, but hit a brick wall because the HSG wanted 300+V to spin up, and the kelly had no feild weakening or anything. The kelly's are great for getting you going, but...

    Kelly KLS-8080IPS, PMSM and RLS rotary Encoder please help

    Check the volts on sine cosine, and they should be the same. If the center is off then the voltages will be different. Honestly I don't recommend the Kelly controllers. I had one running a Hyundai HSG, and the controller would heat up the motor quickly. The Kelly is very inefficient. I...

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Arlo, on the leaf motor, they say it is good for 90mph. How many RPM are you spinning the leaf motor up to? They say 10K is about 90 mph, are you at all worried of the motor letting go at top speed? i see you have done up to 113 mph. Did you change the gearing? running larger tires...

    Kelly 8080IPS motor controller

    HA HA, finally got it to spin. So here was the issue. My amplitude was off. I didn't know the formula and I was guessing at what they wanted. I was close, but off by about 20 pts. Zero point=1023*((Min+Max)/2)/255 Amplitude=1023*(Max-(Min+Max)/2)/255 I was able to download all their...

    Kelly 8080IPS motor controller

    So after dilly dallying around, I got the RLS sine/cosine installed. I had to modify a few parts to get the magnets on the shaft. I had to die the 6mm shaft of the magnet holder I also turned down the head of a hex head bolt to stick into a 6mm hole. I pressed it in and screwed in the...

    Kelly 8080IPS motor controller

    Got the sin/cos in. I am building a mount for it. I bought an aluminum bolt that I will drill to .16" dia hole for the 4mm magnet. I got the connector that mounts to the sin/cos in. Now I need to wire everything up, and get my power supply hooked up to the speed controller. I plan to...

    Kelly 8080IPS motor controller

    oh the emotional rollercoaster!!!! first line, will not work... OUCH.. damb it!!!! second line.. it may work... lol!! Thank you for the info... I am not an electrical guy. I was told a resolver was the same thing as a sine cosine... Guess I'll just try it and then see if the motor spins...

    Kelly 8080IPS motor controller

    So I bought a Kelly 8080IPS with sine cosine input. I am trying to use it on the motor in the picture. The motor has a resolver in it. I was told resolver and sine cosine were the same thing, but now I'm being told other wise. And here is the wiring diagram... The resistance on the 3...

    A123 Chevy Spark modules

    Super difficult. Tabs cells are laser welded and glued as 1 big pack. Best thing u can do is cut the tabs on top and rivit to them....but very sketchy... I have taken these apart down to individual cells.... Very difficult to disassemble and next to impossible to re attach

    DIY battery pack question.

    I build packs, and I think that is fine. If you are worried, you can measure them all and sort by voltage. Then when you are building your pack you can put the same volt cell in the same parallel group. And then use a balance charger to balance the pack out. But I have found it much...

    Suggestions building modular 14s8p for downhill bike

    I have a 14s7p and I pull 150 amps. 21 amps a cell. At full speed full throttle I am pulling 45 amps @ 34mph. I am running 2x 750 brushed motors and my motors overheat be for my batts over heat. So yes you can pull 15-20 amps per cell on Tesla cells. No you can not pull it for too...

    Best 18650 battery for the buck? Best deals?

    I say used tesla because the cells get QC'd. Stay away from Alibaba no idea what u are buying. U rely on the word of a company half way around the world. I have bought many lipos from hk and never had an issue (as in unexpected fire). All my lipos are expanded. Many have failed over time. I...

    Or 3m canceled the contract once 3m found out they were getting cheap chinese batts. And now the chinese mfg is dumping its crap product on stupid people. Show capaity curves at 1c 3c. Buy an icharger. It will do all this. You dont need to be an engineer. You just need an IQ over 121

    Best 18650 battery for the buck? Best deals?

    Buy used tesla cells. it is the cheapest way to get QUALITY 18650BE's Buy from someone who has sold a fair amount so you have a good idea you are getting what they are saying you are getting. If you are making your own pack I recommend not to solder them, and if you are going to solder them...
