In emergency need of DC motor controller

We are at an event in Peoria Illinois and are in emergency need of a motor controller. The motor controller is controlled by an arduino and controls a linear actuator. The acuator draws 33 amps, so we need at least a 40 amp motor controller. Does anyone within 6 hours of Peoria Illinois have a 40 amp motor controller?

Why not use a Talon SRX? That’s a readily available motor controller that can handle 60 amps continuous and can be run by an Arduino over PWM.

Edit: I suggest the Talon SRX (or the Victor SPX, as @kingc95 suggests) because it’s a controller that someone at the event is likely to have on hand as a spare part, since they are very commonly used.


Victor SPX as well, but it doesn’t have a metal body to act as heat dissipation. That may be relevant if sustaining high amperage continuously.

CRC Hobbies may have something that will work. They don’t open till noon though.

An excellent suggestion. These three have essentially identical electrical capacities:
