running steppers at destruction volts and amps
water cooled steppers ??? , my new driver runs at 110v - 220v at 7 amp , plenty enough "grunt and sparks "to make the magic smoke come out of any stepper
umm $75 a 1600oz/inch stepper on ebay , heard there's to much internal inertia and at 22 inductance would need 160 volt to get the best out of it , i feel the need to sacrifice one to the "magic smoke gods" to ease them
just have to figure out how to make a cheep dynamo test rig ,so i can measure the torque in running conditions , have a 24volt brake system coming , so will have to test the performance of the brake v's voltage and set up a test bench , already have a laser Hz gun ( rpm )
so volts give speed , the higher the volts the thicker insulation ,less windings the thicker the insulation
and amps give you torque, more heat with more amps , thicker wire , less windings
dose any one know of any treads on running steppers to destruction
i might rewind a 1600oz at 240 volt, 150c ,4 amp ( after the first magic smoke ) and cover it in 12x 80watt peltier heat pumps and aluminium water cooled heat sinks to get rid of the heat with the over amps , 3 peltier's per side on the stepper ,
dont plan on using them , just want to see how much of a speed / torque advantage savage cooling can provide ( could even freeze the motor over but will thermostat the peltier's at 40c )
while its apart i will look at the magnets ,
