= Main Motor Driver Ideas for Ground Vehicle and Beyond =


== Brushed Motors ==

 * H-bridge Style Modules 
   * [http://www.robot-electronics.co.uk/htm/md03tech.htm Devantech I2C driver] , 5-50V 20Amps ~$70
   * [http://www.ifirobotics.com/victor-884-speed-controller-robots.shtml Victor's From IFI Robotics]  24V 40Amps ~$110
  

== DC Brushless Motor ==
 * Transmotec 42EMB3580N-12 [wwww.transmotec.com main site, go to motors->BLDC]
 * Pittman N2313 - 270 dollars with 12 week lead time 
 * Maxon EC 45 - 400Watt Certain Lead time, 

== AC Brushless Direct Drive ==
 * Kollmegren- Danaher - D061A - 4000 dollars, long lead time just the motor (its so close to perfect I can almost taste it) 
 

= Motor Controller (BLDC) =

I've looked around at a few different BLDC ,
 * Freescale [http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=RD68HC908BLDCMOTOR&nodeId=0MFB28vCs7 eval board ]
 * Atmel [http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3764 Eval Board]
 * Microchip [http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en023545&part=DM183021 PICDEM LV eval board]

From looking at lead time and overall constraints, the PICDEM LV seems to be the best system from the specifications and documentation.  It can be ordered from DigiKey or directly from Microchip, 

= Random Ideas =

 * Use a built AC drive like this [http://web4.automationdirect.com/static/specs/gs2drive.pdf AutomationDirect] Drive and control using serial.  Handles up to 3-5 horsepower, 
 * With a standard AC drive controller, we could try out a few different types of AC motors either surplus or ebay, probably around 1/4-1 horsepower should be sufficient power but the speed x torque is really whats important
