Motor Controller Selection - High Current

Help & Support Robot Parts
1

Hello. I am reaching out to see if anyone can help me with finding the right motor controller for my needs. I am looking for a high current single channel motor controller - 160A or more. We are controlling a 24V brushed AmpFlow motor model A40-300 (http://www.ampflow.com/four_inch_high_performance_motors.htm). We are using this motor to lift a platform so it has a lot of initial inertia to overcome and draws a lot of current upon starting and stopping. I saw the RoboteQ XDC22230S (30V version) and XDC2460S (60V version) on RobotShop’s website. Does it matter which one of those I select if I’m only using a 24V system?

Please let me know if anyone can point me in the direction of other less expensive high current controller options. Thank you in advance for your help!

Sorry I meant to include that I would also like to have encoder inputs on the controller.

@Efft High current tends to involve high prices. The highest current controllers carried by RobotShop at this time are RoboteQ (as you suspected):

You’ll see there are 160A, 200A and even 360A controllers. Normally the voltage rating is a “maximum”, so if you see a model you like, check the manual to see min / max voltage. Both models you list can operate from 10V+. If there’s a chance that your charged 24V battery surpasses 30V by quite a bit, might consider the 60V option. If not, the 30V should be suitable.
