This article discusses speed control of DC motor using android application is the safest way to save power. PWM technique used to control the speed of Motor. PWM involves application of varying width pulses to the motor driver to control the voltage applied to the motor. This method proves to be very efficient as the power loss is kept at . Here TM and TL are the motor torque and the load torques respectively which are expressed as functions of ω.
The application of motors mainly looks at three aspects of operation.
The speed of the machine has to be increased from .
Internet has become one of the irreplaceable tool for commun. Motor Control applications , design and motor control products are available at Mouser, a global authorized distributor of semiconductors and electronic components. Along the same lines, the simple design of DC motors makes service, maintenance and control well understood and easily supportable.
Even speed control is simple: Just adjust the terminal . Earlier days, DC motors were in use, wherever variable speed is required. With advancement of variable frequency drive (VFD), induction motor replaced dc motor in most of the applications.
With access to both the field and rotor windings, all DC motors offer the facility of simple speed and torque control. Lesser the diverter resistance less is the field . Field Control of DC Series Motor. In making the new circuit feasible, . Abstract: The electric drive systems used in industrial applications are increasingly required to meet higher performance and reliability requirements. The DC motor is an attractive piece of equipment in many industrial applications requiring variable speed and load characteristics due to its ease of controllability.
There are three speed control motor product groups.
Motors are normally used for industrial control , automation and home electrical appliance. It spans everything from residential washing machines, fans, hand- held power tools, automotive window lift, traction control system, industrial drives and many more. The microcontroller the controls the DC motor through motor driver.
LCD display is used to show the status and the speed of the DC motor.
The android application is used to control the entire system. The start button is first clicked to start the motor and then the motor can run .
