Bidirectional Rotation of an Induction Motor with a Remote Control Device

Bidirectional rotation of an induction motor with a remote control device is basically a device that controls the rotation of a single phase ac motor in clock wise and anti clock wise direction. In conventional way, we cannot rotate the single phase ac motor in both direction as well as we can only control this motor with a single phase one way switch. In other words, if we want to control the motor in both direction then we must use any sort of motor drive, which could be so much costly, but it would be also operate with single phase one way switch. On concentrating these issues, here we have designed a device that is called a bidirectional rotation of an induction motor with a remote control device.

This device controls the single phase ac motor in both direction forward and reverse with any type of common TV remote. This device has designed with help of single phase ac transformer, bridge rectifier, voltage regulator, IR sensors, single phase relay and microcontroller PIC18F452 belongs to pic family. This device is less costly, more compact and more reliable as compared to other motor drive devices. The block diagram of this bidirectional rotation of an induction motor with a remote control device with all their essential components is shown in figure 1.

Working of Bidirectional Rotation of an Induction Motor with a Remote Control Device

The working of this bidirectional rotation of an induction motor with a remote control device is very simple. For controlling the direction of rotation of any type of single phase ac induction motor such as exhaust fan or any motor, this device is connected in series with main supply of that specific single phase motor. This device mostly consists of electronic components which are operated at 5 or 6V dc. For making 5or 6V dc, main supply is stepped down to 6 or 9V ac with the help of single phase transformer then these voltages are converted into dc with the help of bridge rectifier. After that, these voltages are regulated into 5V dc with the help of voltage regulator.

From these regulated voltages the pic microcontroller and IR sensors are powered up. Microcontroller is the main controller of this device. It is programmed in c language with the help of mikro/c software.IR sensor are basically the infrared sensors which can be operate with any type of TV remote. When TV remote switch is pressed then IR sensors are switched on. When these are switched on, then these gives the logic high signal to pic microcontroller. Then microcontroller efficiently control the direction of rotation of split phase induction motor. Split phase induction motor is directly powered up with 230V ac, but its control circuit is make on or off through microcontroller. In this bidirectional rotation of an induction motor control device, we have configured the remote switch no.1 for forward direction of rotation of motor, switch no.2 for stop and switch no.3 for reverse direction of rotation of split phase induction motor. This have only done for make the convenient for user interface. Two relays have been used for making on or off the split phase induction motor. These relays are derived through relay driver IC ULN 2803.

Applications and Advantages of Bidirectional Rotation of an Induction Motor with a Remote Control Device

1. By using this bidirectional rotation of an induction motor with a remote control device the user can easily rotate the split phase induction motor in either direction.
2. This bidirectional rotation of an induction motor device could be easily used with domestic and industrial exhaust fans for fresh air in and hot air throw out.
3. By using bidirectional rotation of an induction motor device, the user can easily on or off the split phase inducing motor with some distance without wasting any time.
