The Speed Control Of DC Motor By Using PWM Technique project commences with the direct current (DC) motor which is a simple electric motor that. It utilizes fields of magnetic and electricity to create torque that switches the motor. The DC motor is utilized to transfer the electrical into mechanical energy for the purpose of driving loads.
The types of DC motor are Flux control method, Rheostatic Control method, and Voltage control method. The armature voltage control method utilizes armature circuit where Va is different without altering the voltage used in circuit of the motor.
Hence, the motor should make use of armature voltage control. When the voltage of the armature is incremented then accuracy of the motor also increment whereas torque-speed curve seems unchanged and flux is constant.
The Power Point presents the different execution of current voltage in the DC motor. When current is passing by a coil in the presence of magnetic field, then the magnetic force generates the torque that switches the motor.
From the figure in the Power Point, it is seen that the electric current is supplied by the commutator externally. The magnetic force is expressed in the form of F=ILB. It acts perpendicular to magnetic field and the wire.
Conclusion:
The conclusion made based on the principle of operation of DC motor depends on electromagnetism. The conductor which possesses current produces the magnetic field. When it is kept in external magnetic area then force is produced in the field which is proportional to the current and strength of the external magnetic field present in the conductor.
