I am looking for a pmdc motor in a small packaged 1.56" diameter, 5.1" long shaft to shaft. The operating specs are as follows
175 C, operate, 200 C survive
Kt (torque constant) approx 8.2 in-oz/amp
Ke (back emf constant) approx 6 V/krpm
no load rpm approx 5000-6000 rpm
The motor is...
I have some cast rotor and stator blades for a turbine-alternator system. The parts are investment castings. The blades come in as cast in 440C.
We must do finish machining on the parts. What is the typical hardness for as cast 440C part?
