Strictly speaking, there is no such thing as a single phase induction motor, but you can "fake" it (see http://www.allaboutcircuits.com/textbook/alternating-current/chpt-13/single-phase-induction-motors/). Since it involves more components, it should be more expensive, but sales volume might tend to equalize the costs.srinaath said:hi guys...
which will be costlier-single phase induction machine or three phase induction machine for same power rating, same rpm speed, same input voltage and current.?
The cost of a three phase induction motor is typically higher than that of a single phase motor due to the additional components and complexity involved in its design and construction.
The main factors that affect the cost of an induction motor include the size and power rating, efficiency, type of construction, and materials used in its production.
Three phase induction motors are more commonly used in industrial applications due to their higher efficiency, reliability, and ability to handle larger loads compared to single phase motors.
Yes, the cost of an induction motor can vary depending on the manufacturer as different companies may use different materials, production methods, and have varying levels of quality control which can affect the final cost.
The most cost-effective option for your needs will depend on the specific requirements of your application. It is important to carefully consider factors such as power rating, efficiency, and maintenance costs to determine which type of induction motor will provide the best value for your investment.
