Universal AC/DC gearmotors are designed to operate on both alternating current (AC) and direct current (DC) power sources, making them versatile for various applications. These motors are typically series-wound, meaning the field windings and armature windings are connected in series. This configuration allows them to run on both AC and DC power. When connected to an AC power supply, the alternating current causes the magnetic field in the motor to alternate, which in turn induces a current in the armature, creating torque and causing the motor to rotate. The series-wound design ensures that the direction of the current in both the field and armature windings changes simultaneously, maintaining consistent rotation direction. For DC power, such as from a battery, the current flows in a single direction. The motor operates similarly, with the DC current passing through the series-connected windings, generating a magnetic field that interacts with the armature to produce motion. The motor's design allows it to handle the constant voltage and current from a battery without requiring additional components. Universal motors are equipped with brushes and a commutator, which facilitate the transfer of electrical current to the rotating armature. This setup is crucial for maintaining motor operation regardless of the power source type. The gear mechanism attached to the motor provides torque multiplication and speed reduction, making the motor suitable for applications requiring high torque at low speeds. Overall, the ability of universal AC/DC gearmotors to operate on both power types is due to their series-wound configuration, commutator and brush assembly, and robust design, allowing them to adapt to varying voltage and current conditions from different power supplies.
