Concentrated winding in bldc
WebSep 29, 2024 · We designed and analyzed an interior permanent magnet synchronous motor (IPMSM) to prevent irreversible demagnetization of the permanent magnets (PMs). Irreversible demagnetization of NdFeB PMs mainly occurs due to high temperature, which should thus be minimized. Therefore, it is necessary to reduce the eddy current loss in … WebJan 2, 2024 · Different winding patterns may also have an effect. However I suspect that matching back-emf to the drive waveform is often not done, because real BLDC back-emf waveforms are all over the place. Here are some scope traces showing the phase-to-phase waveforms of 3 motors that I tested (vertical pulses are PWM drive, back-emf is the …
