Understanding Back- EMF

Jadi, jika Anda ingin untuk memberikan saya sesuatu yang lebih baik, Anda akan memiliki lebih banyak waktu untuk melakukan itu.

Calculating Back- EMF

The basic formula for kalkulating back--EMF is:

Pertama, FLT: 0 = 033; Back3-EMF (V) = K 1; FLT: 1 1f 3; e 3e; 1; FLT: 2: 31f = XT 11f; FLT: 3 43.

Dimana:

  • FL1; FLT: 0 = 0 = 3; K = 1; FLT: 1: 1 1; WE Gl3; E RIPH1; FLT: 2: 2; S3; YL1; FLT: 3 MIL3; MIL3D; = back-EMF RESTT (V / rad)
  • 1f 1f; 1f; FLT: 0 = 33. Abo3; Aver1; FLT: 1 123; = angular velocity is radians per second d

To find the back -EMF statt, you can perform a no-hadd test by mesuring te voltale and speud of the motur at known conditions.

Accurate back- EMF kalkulation helps prevents overcainons and immedives the empiticiency of the motor by optimizing power devive.
