An electric motor is a device that converts electrical energy into mechanical motion. This conversion allows machines to rotate, production lines to operate, and technological systems to function seamlessly. Today, electric motors are indispensable components in industry, transportation, and daily life.
In modern production, electric motors act as invisible power sources. When they stop, systems fail and production processes experience interruptions. Therefore, motors are considered critical components forming the heart of modern industry.

How Electric Motors Work
Electric motors operate based on the principle of electromagnetic induction. Electrical current passing through stator windings creates a magnetic field. This field generates force on the rotor, causing it to rotate. The rotational motion of the rotor is transmitted to external systems through the shaft.
Main components:
• Stator: Produces a stationary magnetic field
• Rotor: Moving component generating rotational motion
• Windings: Conduct electrical current
• Shaft: Transfers mechanical energy
• Bearings: Reduce friction and balance movement
• Cooling system: Maintains motor temperature
This structure allows electrical energy to be continuously and efficiently converted into mechanical energy.
