Ramming Speed 2: ESC

I am using Victor 883 speed controllers. With the exception of fan mounts cracking, they have worked flawlessly so far. I will use two controllers to power my 4 18v Dewalt motors at 21.6 volts. This configuration has been used before, namely by Wedge of Doom. I will reinforce the fan mounting to prevent failure.

Here is info from the IFI Robotics website:

The 24V Victor 883 is a speed controller specifically engineered for robotic applications. The high current capacity, low voltage drop, and peak surge capacity make the 24V Victor 883 ideal for drive systems while its braking options and precise control meet the demanding needs of arms and lift systems. This controller safely handles the high continuous current draws and extreme current surges produced by robots. Innovative FET switching architecture and an integral cooling fan ensures cool FET junction temperatures. The low voltage drop and high switching speed ensures the motor receives maximum power, providing significant improvements in acceleration, direction changes, and lifting torque.

24V Victor 883 PWM Signal Information

The Victor 883 (for use with standard R/C receivers) comes with a PWM Signal Driver. This PWM Signal Driver ensures the signal from your receiver is compatible with the Victor. The PWM Signal Driver may not be necessary on some receivers or with some external mixers. The Victor 883 (for use with the IFI Control System) does not come with a PWM Signal Driver.

24V Victor 883 Fan Information

The Victor 883 comes with a cooling fan attached to the top of the unit. The 24V Victor can operate over a 6V–30V range, however, fans cannot operate over this wide a voltage range. When you purchase a 24V Victor 883, you must select either a 12V or 24V Fan.
