Suggest me a motor controller
Suggest me a motor controller
(OP)
I want to use a motor controller to control my DC motors and i'd like to receive some suggestions from you before to buy them.

I have a mobile cart with four DC motors and each one has these data (the motors are all the same):
V: 24V
A: 40A
P: 1000W
Can you suggest me a suitable motor controller with USB or RC or RS232 communication channel?
It is very difficult to find a motor controller up to 50-80A which support also USB or RS232 communication.
Can I use one motor controller to control two coupled motors? In this way I use two controller: one for each side ( a controller for 1 and 3 and another one for 2 and 4).
Or I have to use four motor controllers?
Thanks a lot to everyone.

Half full - Half empty? I don't mind. It's what in it that counts.

Can you explain me better, please?
All the motor controller i've seen take the input voltage (24VDC, 50A) and directly connect to the motor.

In past, I used to control my motors (12-24VDC, 10A) with devices like this: http:
I connect the two wire of the motors (my motors has two wires and not three) to the controller and then I control them via USB.
Now i have to control motors which are more powerful (up to 80-90A) and i'd like to use a controller similar to the one I've linked before.
Do you think it is possible?

Four communication or control options:
USB interface for direct connection to a PC.
Logic-level (TTL) serial interface for direct connection to microcontrollers or other embedded controllers.
Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller.
0–3.3 V analog voltage interface for direct connection to potentiometers and analog joysticks.
It is the last item, 0-3.3 V interface that you shall use. It is very well possible that the USB/analogue device you find outputs 10, 5 or 3.3 V. In the latter case you are set. If 5 or 10 V, all you need is a couple of resistors for a voltage divider.
