Heat-resistant plastics are a category of plastics that have gained prominence in industries where conditions range from high temperatures to extreme conditions. With properties such as thermal stability, lightweight, and chemical resistance, they outperform conventional materials such as metals and ceramics. Although heat-resistant plastics may be more expensive up front, their use promises efficiency, lightweight, and low maintenance rates, making them more attractive to industries as diverse as aerospace, automotive, electronics, and manufacturing.
As ongoing innovations in the field of heat-resistant plastics improve their performance and functions in various applications, these materials are expected to play a more important role in the development of modern technologies."alternating current". They are suitable for a variety of applications where reliability and efficiency of operation are always required. These applications include household appliances, manufacturing tools, and air conditioning units.
On the other hand, DC motors operate with direct currents where the electric current flows in only one direction. They are suitable for applications where regulation is essential with relatively high precision speed and where there is a need for a large starting torque. Applications include automotive systems, robotics, and other household appliances.

Part Function
Stator The fixed part that produces the magnetic field is made of rolled steel sheets with insulated wire windings.
Rotor The rotating part that rotates the mechanical load can be of the squirrel cage or wound type.
TREE Transfers mechanical energy from the motor to the driven load; exits the motor housing.
Landings They support the rotor and allow it to turn smoothly in the stator; they can be ball or roller bearings.
End bells Covers at each end of the motor house the bearings and provide structural support; they are made of cast iron or aluminum.
Fan It cools the engine by forcing air over its surface to dissipate heat. It is often mounted on the rotor shaft.
Pregnant It protects internal components from external contaminants and physical damage and ranges from open frame to fully enclosed design.
Types of AC Motors and Their Functions
Synchronous motors
Synchronous motors maintain a constant speed, which is proportional to the frequency of the AC supply voltage. They are suitable when precise speed regulation is essential. This feature ensures that the motor speed is stable; it can change speed depending on the load it receives. It is essential, especially in systems that require tactile control and synchronization.
