Share with your Facebook types of single phase induction motor pdf! It has comparatively longer life.
It cannot be used at far off places which are not served by electric supply. 3-phase alternators which can be used either in the absence of or on the failure of normal electric supply. It has medium starting torque and a nearly constant speed. 3-phase synchronous motor is used for driving continuously operating equipment at constant speed such as ammonia and air compressors, motor generator sets, continuous rolling mills, paper and cement industries. This motor is quite simple but rugged and possesses high overload capacity. It has a nearly constant speed and poor starting torque. It has high starting torque, large overload capacity and a nearly constant speed.
Double squirrel cage motor is used for driving loads which require high starting torque such as compressor pumps, reciprocating pumps, large refrigerators, crushers, boring mills, textile machinery, cranes, punches and lathes etc. It has high starting torque and large overload capacity. It possesses high starting torque and its speed can be controlled over a wide range. Single phase series motor is generally used for driving small domestic appliances like refrigerators and vacuum cleaners etc. It has high starting torque and is capable of wide speed control. Moreover, it has high speed at high loads.
Repulsion motor is commonly used for drives which require large starting torque and adjustable but constant speed as in coil winding machines. It has fairly constant speed and moderately high starting torque. Speed control is not possible. Capacitor-start induction-run motor is generally used for compressors, refrigerators and small portable hoists. Hence, capacitor-start-and-run motors are commonly used for drives requiring quiet operations.
There are many differences between these motor types and you really need to dig into the matter to know which one is right for you. Click here to cancel reply.

There are a couple types of basic AC motors you can build. They also make super science fair projects. It works great and is very easy to build. Meiners, Vol 2, Ronald Press Co.
100′ of 20AWG wire, on a form about 1. 2 ohms, and an inductance of about 2. With this, we could plot speed vs. 2 ohms, and 24mH as an air-core inductor.
