Permanent magnets are an important component of modern starters, widely used in automobiles, power tools, household appliances, and industrial equipment, and in this article, their role and which part of the starter they are used in will be described.
What part of the starter are permanent magnets typically used in?
In a permanent magnet starter, the permanent magnet is usually fixed to the stator. The stator is the stationary part of the starter and the permanent magnet provides a constant magnetic field. When the starter is energized, current flows through the rotor windings, generating an electromagnetic force in the magnetic field provided by the permanent magnets, which drives the rotor to rotate, thus starting the engine.
Role of permanent magnets in starter rotors;
In conventional motor starters, electromagnets are used to generate a magnetic field. This design, though effective, has certain drawbacks, such as the need to consume additional electrical energy to maintain the magnetic field of the electromagnet. In a permanent magnet starter, on the other hand, permanent magnets are held around the rotor to provide a continuous magnetic force through its inherent magnetic field. This not only reduces the energy consumption of the starter, but also simplifies the design and reduces maintenance requirements.

The configuration of the permanent magnets in the rotor is typically installed in a uniformly distributed manner, allowing the magnetic field to create a uniform flux around the rotor. This uniform magnetic flux effectively interacts with the windings on the stator to generate a strong electromagnetic force that drives the rotor to rotate, thereby enabling the motor to start and run. This design not only improves the efficiency of the starter, but also allows it to operate at lower voltages and currents, thereby extending the life of the unit.
Example of a permanent magnet starter application;
In electric vehicles, permanent magnet starters provide efficient and reliable starting and power output, extending battery life.
In household appliances such as washing machines and air conditioners, PM starters make the equipment run more quietly and energy efficiently.
In industrial equipment, PM starters enhance the automation and efficiency of production lines.
Conclusion: The use of permanent magnets increases the efficiency and reliability of the starter, reduces start-up time, and also reduces energy consumption since permanent magnets do not require an external power source to generate a magnetic field, making permanent magnet starters a popular choice in many applications.
