1. INTRODUCTION
In the evolution of electrical technology, the dc motors were
widely used different industrial applications. After the
invention of ac motors especially ac induction motors the
view of industry become changed due to the wide advantage
of induction motors. An induction motor has two main parts
such as stationary part and rotating part. Two parts are
interlinked by mutual induction that is transformer
principle. An induction is known as rotating transformer.
The main advantage of the 3phase induction motors are self
- starting, rugged in construction, good power factor and
low cost but without sacrificing the efficiency the speed
cannot be controlled. The different faults occur in induction
motors are,
Electrical-related faults: The electrical faults may occur
due to the following factors such as unbalanced 3phase
supply, over voltage, over loading.
Mechanical-related faults: The mechanical fault may occur
due to rotor bar broken, air gap eccentricity, damage in
bearing, rotor and stator winding failure
The performance of the induction motor
depends upon the above electrical and mechanical
parameters. So the continues monitoring of induction motor
is needed for safe and reliable operation of industrial induction
motors. The electrical and environmental parameters such as
voltage, current, temperature and surrounding humidity of the
motor, affects the good performance of motor. And also the
mechanical factors such as vibration and abnormal speed affect
the good performance of the motor. Some electrical and
mechanical factors cause the severe damage to the health of
induction motor and also cause severe problem to application
where the induction motor is used.
Today scenario the industry work as fast as
possible to finish the product /service. In many industries, the
induction motors very widely used to process the product .To
ensure the reliable operation of induction motors recent
advancement techniques are used. Due technology
development the monitoring and controlling are done
automatically. Internet of things is the recent development to
control and monitor the motor from remote location. This
method provides easy control and reliability. The reliability
of motor is obtained by continuous monitoring of electrical
and mechanical parameters. If any abnormal value of
electrical and mechanical factors may be detected, the motor
is controlled automatically (i. e) motor is suddenly turn off to
reduce the severe faults.

5. COMPONENTS DESCRIPTION:
A. Arduino UNO:
The advantage of Arduino over other type of
microcontroller is, it’s open source and cost is less
compare to other type of microcontrollers. The simple
in programming it is used many more professionals.
Arduino (Fig2) is a type of ATmega328. Arduino has
analog and digital input/output pins. Arduino board
need 5v dc supply to operate. Arduino UNO is the
heart of this work for data acquisition and controlling
of motor. The condition monitoring sensors, LCD
display are interfaced with input/output pins of
Arduino. The control circuit are added are also
interfaced with output pins of Arduino. Arduino board
has the reset button, pins for connecting external
source (i. e battery) and USB cable. It’s also has

B. Remote monitoring and controlling:
Acquired data is continuously monitored in local center
and also in server .The server application provide the
remote monitoring of acquired data. The program set up in
the Arduino is used in processing the data continuously and
send the processed to the server. By using thinks speak
website the data is seen from remote locations via internet.
If any abnormal condition is noted the is controlled from
remote locations (i. e ON and OFF the motor to reduce
severe faults).
C. Power supply:
Power supply is the circuit (Fig 3) from which we get a
desired de voltage to run the other circuits. The voltage we
get from the main line is 230V AC but the other components
of our circuit require 5V DC. Hence step-down transformer
is used to get 12V AC which is later converted to 12V DC
using a rectifier. The output of rectifier still contains some
ripples even though it is a DC signal due to which it is called
as Pulsating DC. To remove ripple in output voltage the filter
circuit is required. Here a capacitor is used. The 12V DC is
rated down to SV using a positive voltage regulator chip
705. Thus, a fixed DC voltage of 5V is obtained.

The running condition of 3phase induction motor is
continuously monitored by easily configurable and light
weight sensors are mostly used. The sensors (Fig 4) in the
proposed work are DHT11 sensor for measuring humidity,
LM35 for measuring temperature, Piezoelectric sensor for
measuring vibration, Acs712 for measuring motor current,
voltage divider for measuring supply voltage and IR sensor
for measuring speed. In this work the data is acquired by
the Arduino. The Arduino has the ability to process the data,
send the data to cloud storage, store the result in local
center, give the alert message to user and used in control
the applications.

the LCD screen. To interface LCD display to Arduino 4 data
pins, 2 control pins and 2 supply wires (i. e 5V and Ground)
must be connect to Arduino. The processed data is displayed in
the LCD display one by one. And also the additional
requirement of smooth motor operation is displayed.

one ground to operate. Also this module requires two soft
serial ports. The data acquired by the Arduino are processed
and send to server by using ESP8266. ESP8266 require
additional library file to operate. By programming the
microcontroller the data is updated every second. It has
advantage over Bluetooth module (i. e) the data is send to
remote locations. ESP8266 work depends upon the AT
commands.

H. Controller:
1. Relay:
The 5V relay is used in the proposed work.
5V relay (Fig 8) is directly connected to the Arduino. Pulse
from the Arduino is given to relay, the output of relay is the
input of contactor. If any abnormal condition is detected by
the Arduino from acquired data the command is given to
Arduino to relay to open the contactor. In this work single
pole single throw switch relay is used. The relay has the
5pins NO(normally open),NC(normally closed),5V,GND and
common pin. There is no need of external itself, Arduino is
provide enough supply to relay. The relay is work on the
principle of electromagnetism, when supply is given to relay
it act as a electromagnet and change the state of the switch.
The supply given to Arduino is independent of the supply
which to be turn ON and OFF.
Fig 8.Relay
2. Contactor:
The 3phase supply is given to motor through the 3phase
contactor (Fig 9) . The contactors are mainly control the
motors in industry. It has three input and output path, the
supply is given to motor through the contactors. Contactor is a
electrically controlled switch, used for switching the motor
circuit. Other than relay contactor is directly connected to the
high load current. The state of the relay may used both
normally open and closed applications. The contactor has the
ability to reduce the arc. The rating of contactor depends upon
the load current per contact. The switching of 3phase contactor
depends upon triggering pulse from the 5V relay. If
programming the Arduino depends on the smooth operation
motor, the switching signal is given to contactor. The data
acquired by the controlled is processed and compare with the
normal value and any abnormal condition is sensed then a
opening and closing command is given to Arduino. The
contactor is helpful maintaining the healthy condition of
motor. By switching the motors depends on the data, the motor
protect from overloading, over current and high temperature.
