Persamaan transistor fdb 8447L8/31/2023 ![]() The size of the iron core is related to material, current, frequency and voltage, which is called iron loss.Ĭopper loss and iron loss are reflected in the form of heat, affecting the efficiency of the motor. There is hysteresis eddy current effect in the iron core, producing loss in alternating magnetic field. If the current is not a standard DC or sine wave, it will also produce harmonic loss. If the winding is with a resistance, there will be electric loss which is proportional to the square of resistance and current. ![]() ![]() The internal of common types of motors are iron core and winding coil. So the control of pulses’ number, frequency and the power on sequence of each phase winding of the motor affect the rotation of the stepper motor. The angular displacement of the output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency.Ĭhanging the order in which the winding is energized will reverse the motor. Every input of an electric pulse leads the motor to rotate at an angle to advance one step. When the vector magnetic field of the stator rotates an angle, the rotor also rotates at an angle with this magnetic field. The magnetic field will drive the rotor to rotate an angle, so that the direction of magnetic fields of the rotor is consistent with that of the stator. When the current flows through the stator winding, the stator winding produces a vector magnetic field.
