Prinsip Dasar Motor DC

Motor DC bekerja pada prinsip bahwa konduktor pembawa saat ini akan dipengaruhi oleh gaya elektromagnetik di medan magnet . belitan stator diumpankan dengan arus eksitasi DC untuk menghasilkan medan magnet eksitasi; the main circuit introduces a DC power supply, which is transmitted to the commutator through the brush, and then the commutator converts this DC power into an alternating current and passes it into the armature winding to generate an armature magnetic field. The armature magnetic field and the excitation magnetic field form an air gap magnetic field. The armature winding cuts the synthesized air gap medan magnet untuk menghasilkan torsi elektromagnetik untuk menyebabkan rotor memutar . ini adalah prinsip kerja dasar motor dc .

Model motor DC dua kutub terdiri dari kutub magnet utama (kumparan eksitasi), jangkar (koil jangkar), kuas dan komutator . sepasang kutub magnetik utama statis DC yang dipasang pada stator, dan kutub magnetik utama dihasilkan oleh medan magnet dari koil eksitasi; Rotor dilengkapi dengan inti jangkar dan belitan jangkar . arus jangkar dihasilkan oleh catu daya DC eksternal, dan ada celah udara antara stator dan rotor . {} {{{{{{{masing-masing {{{{{{{{{{{{{masing-masing berbentuk lain dihubungkan masing-masing, dan masing-masing. whole composed of commutator segments is called a commutator. The commutator is fixed on the shaft and is insulated from the shaft. A pair of fixed brushes are placed on the commutator segments. When the armature rotates, the armature coil contacts the external circuit through the commutator segments and brushes, and an external DC power supply is diperkenalkan .

When the DC motor is running, the DC power supply is connected between the two brushes. The direction of the current is: the current on the effective side of the N level is always in one direction, and the current on the effective side of the S level is always in another direction. The electromagnetic force on both sides is in the same direction, so the armature rotates. When the effective side of the coil turns from the N level below (S level above) to the S level above (N pole below), the current direction changes at the same time due to the commutator segments, while the direction of the electromagnetic force remains unchanged, so that the armature is subjected to an electromagnetic torque with a constant direction. The armature of the DC motor is composed of multiple coils, so the electromagnetic torque generated by the coil is relatively seragam dan tidak akan ada terlalu banyak denyut nadi, sehingga motor dapat berjalan terus menerus dan lancar .
