Hiya, playing with W = I`R. Where I = 12.5A(max) and R = 3 ohms leaves me with 486.75 watts is this correct?
Background: using a L297 to drive a mosfet H bridge to run a 2 phase bipolar step motor. Yes, I want full step (.0005" resolution per step). I want to use the chopper circuit to the sens inputs on the L297. My power supplies output 38.4V, 12.5A dc unregulated. Using 1 power supply per motor. thx for your help
