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).

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...

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

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...

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...

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...

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...

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...

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...

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...

Ok, just bought the sin/cousin u suggested. Thank you Eric

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...

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...

You left out the plastic dividers... why did you do that? I am not 100% sure they are NEEDED but they come from the factory with them, so I would think they may be needed...
