Electric vehicle controllers and control systems

most electric scooters controller function are the same, offer the circuit for visitors info .

Hello I am new to this forum. I have a couple of questions. I was wondering if anyone could help me out.

1.)If you run a 24volt 40amp controller on 36volts, the motor should have more power than a 36volt 30amp controller on 36volts. Right?

2.)And if you use two 40amp controllers on two motors it should be 80amps X 36volts= 2880 Watts? (the motors are rated for 36amps each)

Thanks

Hello all, a new member here. Thought maybe someone could help me. I have one of the TRX 3-wheel scooters that was purchased at the end of January 2005. The controller burned out last summer and looking to replace it. The controller removed has 2 bunches of wires. On one side there are green and blue wires (about 16 gauge) coming out and going into a plastic socket connector and on the other side, there are what looks like a main black and red wire which end with barrel type connectors.

this bike was a prize a few years ago that was one at a bar draw... it only worked for a few weeks till things started going wrong with it! Does anyone recognize this controller or can they suggest a good replacement? it's a brushed motor, only 250w, 48v and i wanted to fix it up for my parents to use at their campground.

Hello All:

This is for you electronics engineers out there..

With electric bicycles there's an option between having a throttle or not having a throttle. Traditionally a throttle-less electric bicycle was called "pedelec" or "pedal electric". The pedelec design lacks a throttle and instead controls the motor power in some other way.

The Charger bicycle was a pedelec design and there have been others over time. It seems though most electric bicycles have a throttle.

I have a 24v DC reversible motor rated at 45 amps no-load and 145 amps loaded. Supposedly it is a Ramsey winch motor: ebay.com 230333899614 I'm using it on an electric aircraft tug. I posted some questons under "Other Electric Vehicles" and then discovered the "Control Systems" Forum, which seems more appropriate for my questions!

Hi,

I am very new to building electrical components but I am trying to get a simple design and then build a light sensitive door opener for my chicken coop.

It would need to run off a small battery. It would only need to lift or push a door weighing no more than 100g. It would either need to be operated by light sensitive switch or a timer. It would all need to be housed in a waterproof housing.

Can anyone out there help me with this.

Many thanks
Mitch

Im wondering if I instal a 60v controller on my 48 volt system will I get an increase in speed at all or is it just a waste of money the specs for my scooter are below v
