Synchronizing Motors

Roboteq,

The droid that I'm building utilizes a pair of AmpFlow A28-400 motors that together drive a single drive-shaft, similar to how Teach Whyachi pairs two A28-400's using spiral mitre gears (www.teamwhyachi.com/Twm3R.htm). In my case the motors each have 12-Tooth Spur-Gears that drive a 48-Tooth Spur Gear on a drive-shaft.

Both motors will be driven by one of your HDC2450 Dual-Channel controllers (really awesome controllers BTW!). For my application, I need both motors working at the exact same time for all functions both when producing power and when regenerating. I know the HDC2450's can do the job per the stats, but I am concerned about damaging the controller and/or the motors by getting the timing wrong.

My question is this; Would it be wiser to use a single-channel HDC2450 and connect both motors in series? Or can I use the dual-channel HDC2450 safely with this configuration?

Any advice or input would be most welcome. :)

Thanks!

Kris

How exactly are the motors driven? The utility in itself allows you to drive the motors syncronously.

If driven by 1 joystick, or remote, you set it as motor command for both channel 1 and 2.

If you are sending motor commands via serial, you send the commands as a 1 line command using the "_" to combine the command. It works as a carriage return.

!G 1 500_!G2 2 500 would cause motor 1 and 2 to receive the same command at the same time.

Roboteq Support,

Thank You for the response! =) Very good information!

To answer your question, I will be initially controlling the motors via joystick while I build and test the droid's drive system. Once complete, it will be driven via RS232 Serial commands from an Arduino Mega most likely.

Cheers!

Kris
