WebThe block runs the motor using closed-loop field-oriented control (FOC) with a limited speed during which it runs the tests to estimate back-emf constant (K e) and viscous damping (B).After a pre-configured duration, the block concludes these tests to compute K e and B, and then, triggers coast-down by shutting down all six inverter switches. WebSep 12, 2024 · Consequently, an emf is induced in each circuit by the changing current in the other. This type of emf is therefore called a mutually induced emf, and the phenomenon that occurs is known as mutual inductance (M).
