Electric vehicle controllers and control systems

Hy guys I am new here found the site while doing a search. I am looking for a high voltage brushless sensorless controler. Need to be able to handle 120 volts at the least and more would be better. It also needs to be rated for at least 200 amps.

Thanks in advance for the help

I'm building an Ebike, and here's my dilemna.

I found out I can wire a Crystalyte 5303 with a Kelly regen 100A controller. Regenerative braking is what I'm shooting for. Standard Crystalye controllers don't have it. However, Steven at Kelly Controllers informed me, I can't get a two-way twist throttle (forward/reverse) for braking, and I would need a seperate 5kohm pot or 5v sensor for regen braking.

Here's my question.

What if I use two twist throttles?

- One on the right for throttle.

- One on the left for Regen braking (twisting forward).

I have a recumbent bicycle project that I am just starting. The bike has a a 26" rear, 20" front wheel. I would like to install a hub motor in each wheel. Why? Because I can!!! Is it possible to operate both motors with one string of batteries and one controller with the controller being sized for the max current draw of both motors together?

After straightening out the wiring on my newly acquired electric "cargo trike" I still have one connector that is unidentified. How can I tell if it's supposed to go back up to the dashboard, to light up the stock battery gauge and/or the brake light? Is there a wiring standard color code. Or is it the proverbial "OOPS DAMN - I let the smoke out of another one" trial and (expensive) error method? It's this controller:

Hello forum members,

I have a question regarding the paralleling of #CT-302S9(rated 24 volts,30 amps) power controller for a clone electric scooter(not home-built) to help in acceleration/hill climbing ;will wiring 2 of the #CT-302S9 pwr controllers work well on my scooter??

I am thinking it may work since the p.c. is a Hall-Effect type(no resistance reduction),but I am not sure exactly how to wire the 2 p.c. regarding the speedometer control circuit on the p.c.

As a general rule, I hate finding questions on forums that have been answered dozens of times. Even more, I hate ASKING those questions, but I think I've spent enough time searching this site and NOT finding the answer I'm looking for. I've seen several sites with controllers for sale with various numbers of ports available. That's not too tough - starts with power in, power out and throttle ports, and goes up from there.

My crude understanding needs some reassurance or clarification .Therefore, this is a request for anybody so graciously share input on the following subject:Looking at the specs of both XB-600 & XB-508 they read 48 Amp Circuit & 56 Amp Circuit respectively .Does it mean that the XB-508 controller would allow more current to flow ? Would it more likely resist better modding ? Would then the hub be allowed to develop more torque ? Note that the 508 controller sells more expensively .And finally : Does the 508 controller puts out 19 wires ? Thank you in advance.

I have just received a cute 36v Mini-Moto gokart , for which there is no wiring diagram available nor is there a controller available from the original distributor. I can make the motor run by hooking it up directly and it will run at one speed in one direction.

My problem is that I have no clue as to how the controllers work. I am confused about the throttle which seems to work through a magnetic field as there is no rheostat-like device. What kind of signal is sent to the controller?

Ok, I bought a 48V 1000W Electric Scooter Speed Controller. 48 Volt 1000 Watt output. Designed for 500-1000 Watt motors. Under Voltage protect 41 Volts. Current limiting feature prevents controller damage due to over-current conditions. Under voltage protection feature prevents over-discharge and extends battery life. 12AWG battery and motor connection wires. Uses variable speed hall-effect throttle.
