RDDLZ AC synchronous gear motor is an electric motor that operates at a constant speed of 15 rpm when supplied with alternating current (AC). This synchronous motor is commonly used in automation, conveyor systems, clocks, and other industrial machinery where stable and consistent speed control is essential.

Tips: How is the synchronous characteristic of AC synchronous motor achieved?

The synchronous characteristic of an AC synchronous motor is achieved by ensuring the rotor speed matches the frequency of the stator's rotating magnetic field. This synchronization is due to the rotor's construction and the magnetic interaction between the stator and rotor.

The stator generates a rotating magnetic field when an AC supply is applied. The rotor, typically equipped with permanent magnets or electromagnets, aligns with this field due to electromagnetic attraction. Unlike induction motors, where slip exists, the rotor of a synchronous motor is "locked in" with the stator field.

To achieve synchronization, the rotor must be brought near synchronous speed during startup, often using auxiliary methods such as damper windings or an external motor. Once synchronized, the motor maintains constant speed regardless of load variations (up to a critical point), making it highly suitable for applications requiring precise speed control.
