What is the function of a reversing magnetic motor starter?

The function of a reversing magnetic motor starter is to provide a magnetic method of changing a motor's direction of rotation. This device is equipped with multiple contacts and coils that allow it to connect the motor to the power supply in a way that alters the polarity of the phases supplied to the motor, effectively controlling its direction.

By using electromagnetic coils, the starter can reverse the phases, which changes the rotational direction of the motor. This capability is essential in applications where motors must frequently change direction for tasks like material handling, conveyor systems, or machinery operation requiring forward and reverse motion.

Other functions listed, such as increasing motor speed, reducing voltage, or monitoring temperature, are not within the primary scope of a reversing magnetic motor starter. Instead, they pertain to different types of motor control devices or functions that address speed control and protection.
