EQM4810 Single Phase Motor

Instead of using a commutator to regulate the current inside the coil, EQM4810 single phase motor uses an electronic commutator to deliver the current, which produces an alternating current signal that causes the motor to drive. The working principle of a single phase motor is similar to that of a brushed DC motor. In a single phase motor, the current-carrying conductor(stator)is fixed, while the permanent magnet(rotor) is in motion. When the stator coil receives power from the power supply, single phase motor becomes an electromagnet and begins to generate a uniform magnetic field in the air gap. Although the power supply is direct current, the switch still produces an AC voltage waveform with a trapezoidal shape. Due to the interaction between the electromagnetic stator and the permanent magnet rotor, the rotor continues to rotate. By switching the winding to high and low signals, the corresponding winding are excited for the north and south poles. A permanent magnet rotor with a north and South Pole is aligned with the stator pole, which causes the single phase motor to rotate.
