Baluncore's latest activity
-
Baluncore replied to the thread Digital phase converters for running 3-phase motors.Your diagram is correct, but the voltages are confusing because you do not indicate if a voltage is Vrms or Vpk, so it is hard to... -
Baluncore replied to the thread Digital phase converters for running 3-phase motors.This is one way to convert a single phase, active with neutral, into three-phase lines with 120° separation. The neutral becomes the...

Baluncore replied to the thread Digital phase converters for running 3-phase motors.A 3PH supply is just three single phase lines relative to neutral, the phase differences are 120°. The phase voltage, is the voltage...
-
Baluncore replied to the thread Digital phase converters for running 3-phase motors.That is the basis of the VFD solution. Alternately, by using a phase shift capacitor to drive the third phase, the circulating field...

Baluncore replied to the thread Engineering task: How prevent metal balls from getting stuck when flowing down and out of a cylindrical container?.Two balls, with surface friction, can build a wedge across the exit tube. That is because the balls counter-rotate and can lock like a...
-
Baluncore replied to the thread I Why are continuously emitting radio pulsars not detected?.A pulsar is a noise source that pulses in a noisier background. The detected signal from the brightest pulsar, fed in real time to an...
-
Baluncore replied to the thread Making a compressor from a steam engine or Tesla Turbine.Efficient steam engines tend to be two stage compound engines. What type of steam engine do you have for the project? Are you able to...
-
Baluncore replied to the thread I E field in a wire.1. In the first case, no current flows through air, so the E-field will be a dipole field, centred halfway along the axis between the...
-
Baluncore replied to the thread I Time interval terminology.The astronomical term is "Synodic Day", because that Earth rotation is measured relative to the Sun, not (sidereal) the stars. The term...
-
Baluncore replied to the thread I need a concave mirror with a focal length of 150 feet.Why circles? If the mirrors are rectangular, lay them out in a rectangular grid. You only need to place accurately calculated shim...
-
Baluncore replied to the thread I need a concave mirror with a focal length of 150 feet.That was a well-balanced tree with a flexible hinge, so you could have used a wedge in the back cut, rather than a rope. The problem...
-
Baluncore replied to the thread Making a compressor from a steam engine or Tesla Turbine.There is little conceptual difference between a pump and a motor. Old gasoline engines have been modified to use one end-cylinder as a...

Baluncore replied to the thread I need a concave mirror with a focal length of 150 feet.Spoil sport. You could quietly use an industrial IR laser to start the fire during an electrical storm, then as a good Samaritan, you...
-
Baluncore replied to the thread Multiple signals controlling relay.Use an N-chan MOSFET to drive the relay, controlled by the MC, with pull down on gate. Can you program the MC to remember the "force...

Baluncore replied to the thread I Could anyone give me a step by step guide to using VASP for DFT calculations?.https://en.wikipedia.org/wiki/Vienna_Ab_initio_Simulation_Package
