Hello, readers welcome to new post. In this post we will discuss Difference between Synchronous and Induction Motor. A motor is a device employed to convert electrical power to mechanical. There are different types of motors according to construction working and application.
Here we cover details about the synchronous motor and induction motor and make comparisons among them. So let get started.
Difference between Synchronous Motor and Induction Motor
| Synchronous Motor | Induction Motor |
| When input supply is provided to stator of motor its moves at the synchronous speed. Synchronous speed is the rotation speed of field provided at the stator. | The speed of rotation of an induction motor is less than the synchronous speed. |
| Its rotor is connected with the separate direct current source that provides field the rotor for self-starting process. | Induction motor is self-starting there is no need of any separates direct current source. |
| During initial process of motor there should be rotation speed of rotor equal to synchronous speed. If it happens then the rotor linked magnetically with the poles crated at the rotor by the field, so rotor continues its operation at synchronous speed. | There is no need of any separates circuit for starting of motor. |
| The main difference between induction motor and synchronous motor is that synchronous motor needs an exterior dc supply. | It lacks a dc source. |
| Slip rings and carbon brushes are connected with the synchronous motor. | There is no need of slip ring and carbon brushes that make its construction simplest. |
| This motor needs special circuit for a rotor to rotate at synchronous speed. | No special Circuitry required. |
| The value of power factor of a synchronous motor can be lagging, unity or leading | Due to inductive load, it always operates at lagging power factor |
| The efficiency of these motors is higher than induction motor. | Its efficiency is less than a synchronous motor. |
| Its price is also higher. | It is less costly. |
Synchronous Motor Applications
- These are some applications of synchronous motor that are mentioned here.
- The main purpose of installation in different power systems is to maintain the power factor.
- These motor also employed in voltage regulating applications.
- It used in such systems where less speed and higher loads are working.
- Compressors mostly consist of synchronous motor.
- Cranks, grinders or where high power load is working where these motors are used.
That is all about the Difference between Synchronous Motor and Induction Motor have discussed all the paraments. So if you have any further query ask in the comments. Thanks for reading have a good day. Thanks for reading see you next psot.
