AI Thread Summary
To reconfigure a permanent magnet generator (PMG) to drive a turbine compressor, it must be adapted to function as a motor, which involves changing the electrical input configuration. The generator's stator needs to be supplied with electrical power to induce movement in the PM rotor, but this requires proper commutation to manage the stator current based on rotor position. Brushless DC motors typically achieve this through Hall Effect sensors or induced voltage sensors for current control. The discussion emphasizes the need for a mechanism to reverse the stator current effectively to enable motor functionality. Understanding these electrical dynamics is crucial for successful reconfiguration.

URGENT: PM Generator in Reverse

If you have a permanent magnet generator being driven by a turbine and the generator outputs some power level, how would the configuration of a generator change if it is suppose to drive a turbine's compressor stage with the same power?

I think the meaning is how would one change the generator to a motor that supplies the same output power.

I just don't understand applying electrical power to the stator would make a PM rotor move.

Any details would be appreciated.

"Generators" with permanent magnet (PM) rotors run well as dynamos but not as motors. The dynamo would require some way of commutating (reversing) the stator current depending on the rotor angle. This is done in BLDC (brushles dc) motors that either have a Hall Effect sensor, or use a stator coil induced voltage (from rotor) sensor to commutate the stator current.

Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
