Setup - The hall sensor setup had an automatic learning feature which made getting the hall phase combination a very easy process, took about 1 min to learn after I figured out the correct sequence in the software I needed to get it to learn the combination. It came with instructions, but they need to be clarified a bit. The motor torque ripple will be reduced to the minimum, so as to ensure electric vehicle to run without any noise and vibration, smoothly, and comfortably.

Sabvoton Controller 72200

Phase current control based throttle - This makes riding very nice. It has a variable up/down time limit settable in milliseconds to help buffer out any throttle jolts that happen while riding. The throttle voltage end points are adjustable so it will match any pot type throttle or hall based throttle and provide full range. The throttle mid point and also the phase current mid points are adjustable so that you can customize the throttle curve. Cons - largish, about the same as a 24 FET Xie Chang / Lyen, I'll post up some pics for comparison, buggy android software, programming software is a little clunky, but works well. So far, I tested all those controllers on a 72V 35Ah lead acid battery, on my electric motorbike, with 16 inches 3000W QS V3 high speed motor. I also tried a big 250A continuous Lingbo sinewave controller. It seemed far inferior to me than the sabvoton. Lots of throttle lag, weird regen, seemed somewhat less powerful or barely equivalent to a 150A sabvoton, seemed very inefficient in terms of power consumption, the programming software wasn't good.... So far the sabvoton remains my absolute favorite. Full disclosure, I will be selling these units because I like them. I will start a separate thread in the appropriate for sale section, so please keep that discussion in that thread.

It takes only 3 minutes for the motor to be well matched on its best electronic angle at the first time. Here are some pictures to get a good idea of it's physical size. It's very similar to a Xie Chang 24 FET, but it's much heavier and the quality of construction is vastly superior.

If I’m successful with a repair I’ll provide details. Unfortunately I’m not able to attempt again until November. I evaluated on contruction, pricing and feature set, ended up choosing this controller. I would really like to get this company or Adappto to use a power stage setup I've designed so I can start selling high power controllers. I have the gate drive/power stage figured out, but don't have my own controller brain and don't desire to design my own at this point. You have to understand here that those two controllers have a very different technology. Square wave for the Kelly and Sinewave for the sabvoton. Kelly is also doing square wave controllers, but I never have the opportunity to own one so far.

If you don't want high top speeds, but you want high voltage, what are you doing? Every reduction gear stage robs you of several percent efficiency. For a mid drive it's most efficient with just 1 stage, chain to drive gear. If you don't need high speed, then you don't need high voltage, you need a motor that has the correct KV. For that matter if you did want high speed you could do it with low voltage, it would just require more amps. I'll only talk about the 72200 vs the 12401, since the 72150 is pretty much the same as the 72200, only with less power. I think I have TPS dead low 20, and TPS dead high 70. I understand these as limits for throttle, corresponding to 0-5V throttle output signal. Every throttle is a bit different, but real values are probably more like 1-4 V. So 1V corresponds to TPS dead low 20 (20%), and upper 4V as TPS dead high will be lets say 80 (80%). Thats how I understand it.[/quote]MQCON(Sabvoton)is a high-tech enterprise specializing in researching, developing, manufacturing and marketing the motor controller，here are some other types maybe workable for you. Kelly: the start up is quite rough from 0-5km/h, lots of vibrations, lots of horrible noise like the thing is gonna explode. This is normal on square wave controllers, but not really nice. The start up torque is good, given the weight of my machine. Once passed 5kmh, and until about 30km/h, the motor sound is really fun and nice, sounds almost like a Formula one engine. There is plenty of torque and it doesn't take much time to reach 30. Passed that speed, the sound becomes less audible and the torque seems to decrease, or at least to reach a flat curve, until you reach the top speed, which on my machine was 97km/h. On deceleration, the slide regen was not noticeable since it can only be set up to a very low value. I don't use the regenerative breaking so I cannot say if this works fine, but I saw in the software that it can be set to 50% of controller max power, which is not actually very high too. for my maguara twist throttle, I was told to set the TPS dead low to 5% .....because at a higher setting, the throttle would not send power to the motor until it had been turned 1/2" of twist....which I did not like it that way.[/quote] It takes only 3 minutes for the motor to be well matched on its bestelectronic angle at the first time. The precise current ring can provide accurate torque input to meet the requirement of large torque output during vehicle starting and climbing.
