Please log in for more thread options PSpice for a simple DC motor going forward/stop/reverse using a 12Vdc source My application is a power window DC motor controlled by up/neutral/ down window switch - any tips/ideas? | ||||||||||||||||

Please log in for more thread options What exactly are you trying to simulate? The motor as a load, or the terminal behavior of the motor, with position out vs. volts in? Are you asking which of the above mentioned tools would be best for this? -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software? "Applied Control Theory for Embedded Systems" gives you just what it says. See details at http://www.wescottdesign.com/actfes/actfes.html | ||||||||||||||||

Behavior of the motor - showing outputs (voltage, current, speed) when the up switch is pressed and then the same for when the down switch is pressed with the motor spinning the other way to roll down a window I guess I need an H-bridge type circuit | ||||||||||||||||

Plus: 1. When the switch is released, and it goes to neutral, do you want to brake the motor or let it coast to a stop? 2. Do you want to have limit switches at the ends of the window's travel or do you just want stall current to be drawn until the switch is released and goes to neutral? JF | ||||||||||||||||
