    Writing data on hard disks; It is made on discs made of metal, glass or plastic, the surface of which is covered with iron oxide or other magnetic material. Since the data in these recording media is recorded by magnetization, it remains constant until it is deleted intentionally, and it is not lost in cases such as power outages, as in computer memory chips, which is why they are named as such.
    Brushless direct current motors are synchronous motors powered by direct current electricity through an inverter or switching power supply that generates electricity in the form of alternating current to drive each phase of the motor through a closed-loop controller. The controller provides pulses of current to the motor windings, which control the speed and torque of the motor. This control system replaces the commutator used in many conventional electric motors.
    The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed, almost instantaneous speed and torque control, high efficiency and low maintenance. Brushless motors are used in places such as computer peripherals (disk drives, printers), handheld power tools, and vehicles ranging from model airplanes to automobiles. In modern washing machines, brushless DC motors have led to the replacement of rubber belts and gearboxes with a direct-drive design.
    The brushed DC motor was invented in the 19th century and is still common. Brushless DC motors became possible with the development of solid state electronics in the 1960s.
    The electric motor creates torque by keeping the magnetic fields of the rotor (the rotating part of the machine) and the stator (the stationary part of the machine) in misalignment. One or both groups of magnets are electromagnets made of coil wire wrapped around an iron core.
