Motor Pwm

AI Thread Summary

A PWM controller rated at 6-90V, 15A, and 1000W is suitable for a 3-12VDC gear motor with a no-load draw of 1.5A and a stall current of 25A. The controller's voltage and current ratings exceed the motor's requirements, ensuring safe operation. The discussion highlights the importance of matching PWM specifications to motor characteristics for optimal performance. The user initially sought guidance but found relevant information independently. Proper selection of PWM controllers is crucial for efficient motor control in machine applications.

I'm building a machine using a 3-12VDC gear motor, 1.5A draw no load, stall at 25A. Would a PWM rated at 6-90V 15A 1000W be an appropriate controller?

Nevermind it took some time but I found an article that helped me.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
