WebThe motor parameters that are usually used in motor control are: stator resistance, stator inductances and the magnets flux linkage (or the back-emf constant). The stator resistance and inductance can be obtained very quickly with line-to-line impedance measurement for different rotor positions or through a short-circuit test. WebIt is a fact that a stepper motor generates a “back voltage” when the rotor spins. It’s called a Counter Electromotive Force, or counter EMF. Spin a permanent magnet inside a coil and it will generate a voltage. The polarity of the voltage that’s generated by the stepper motor is opposite or “counter” to that of the power supply.
