Induction Motors from India

'Shamruthi Induction motors' is our flag ship brand tailor made to industrial specifications. These rugged induction motors are designed and tested according to the prevalent stringent British and global standards. They are constructed using rugged cast iron, giving them the strength to take up heavy workload and wear and tear.

It is also a testimony to the quality of Shamruthi Induction motors, that we are offering a 12 month warranty even against any manufacturing defect, which is another first from Prane Engineerings. Easy to maintain and use, Shamruthi Induction motors is ideally suitable for all kinds of industrial applications, across the world.

Electric Supply Rating:

Our induction motors as manufactured according to the prevalent electric supply ratings in different countries, enabling them to work under different voltage fluctuations and giving them longer life. Three phase motors are suitable for 415 V = 10% 3 phase,5 HZ = 5 % supply. For combination of voltage and frequency maximum variation of 10% is allowed.

Single phase Shamruthi Induction motors are suitable for 220 V = 10%,50 HZ = 5% supply.For combination of voltage and frequency, maximum variation of 10% is allowed.

Frame and End Shields:

The alignment and grade of iron used for manufacturing frames has a great impact on the frame's ability to withstand vibration. To ensure this our stator frames are manufactured from high-grade cast iron, this being the case with our end shields also. This process also makes them highly resistant to corrosion and gives them exceptional strength, ensuring their working with the minimum possible vibration.

Hardware:

Corrosion of the hardware is a major reason for the quicker wear and tear of Induction motors. We have foreseen this problem and it is seen to it that all hardware is electro-zinc plated for superior corrosion resistance. This superior corrosion resistance makes them suitable for weathering different climatic and geographical conditions.

Finish:

Adequate care is taken to clean and spray all exposed surfaces with a corrosion inhabiting coating. Stringent Quality measures adopted by Prane Engineerings ensures that all the components are mechanically as well as chemically cleaned. This is followed by the application of a phenolic rust proof primer, which gives excellent protection against corrosive agents. The final assembled Shamruthi Induction motor is then painted with super enamel paint, giving it a rich finish at par with international standards.

Terminal Box:

Terminal boxes are designed in a unique way. This has been done after extension research into the requirements of the industry. Our Terminal boxes are rotatable by 4 X 90 increments, thereby permitting cable entry from any direction. The terminal box is well sealed and placed at the right hand side of the frame. Earth terminal is provided to all Shamruthi Induction motors, protecting them against vulnerabilities of electric fluctuations.

Manufacturing Range: 0.18 KW to 2 KW, speed standard rpm.

Testing:

Our testing procedures are comparable to the prevalent international standards. The process of testing starts right at the manufacturing stage. Each and every components is put through a series of stringent tests. This process culminates at the dispatch stage, where again a series of tests, ensures that a high level of Quality id maintained. This firm commitment to Quality Standards at all cost, has been the prime reason for our Shamruthi Induction motors gaining a niche for themselves, over such a short period of time.

Insulation

Insulation plays an important role in the longevity of a motor. Shamruthi Induction motors manufactured at Prane Engineerings are insulated again on the lines of international standards. We are probably the first in the industry to offer customized solutions according to the buyers requirement, as far as insulation is concerned.

All Shamruthi Induction motors are of class 'B' and 'F' insulation according to the customer's requirement. This coupled with temperature regulation to class 'B' limits, ensures, ruggedness, reliability and longer life.

Duty Rating

All motors are continuously maximum rated at type 50 HZ.

Ambient Temperature

Standard Shamruthi Induction motors are designed for operation at an ambient temperature keeping in mind the geographical difference in temperature. The motors have been designed to work in relatively cooler climes to sub-tropical climatic conditions. Generally speaking the Shamruthi Induction motors have been designed to work at an ambient temperature ranging between 20 C to 45 C.

Altitude

Stringent adherence to quality standards ensures that our standard motors are designed for operation up to an altitude not exceeding approximately 1000 meters above sea level. For higher altitudes derating of output KW is required. As the standard motors are already designed to work under varying temperatures and their ability to work at variable altitudes makes then suitable for industries across the globe.

Mounting

Mounting of Shamruthi Induction motors plays a vital part in the design of motors and their ability to continuously work under stressful conditions and also their ability to withstand vibrations. Keeping this in mind our Shamruthi Induction motors are available in foot mounted and frame mounted designs.

They are designed in such a manner so as to minimize the vibrations, which in turn gives them a longer life even under tough conditions.

Bearings:

Extreme care has been taken to select the correct specification of ball bearings for trouble free functioning of our standard motors. Standard motors are fitted with high quality, double side sealed, C3 clearance ball bearings.

The customers also need not worry about the lubrication of the bearings as they come with pre-packed lubricants. This lubrication of moving parts in our standard motors make them ideally suitable for running for long hours at a stretch, ensuring the same high standard of production, at the same time.

Cooling System

Special attention has been taken to provide Shamruthi Induction motors with adequate airflow. Cooling fans are cast integrally with stalor frame and end shields. External fans come with the stator frames. Specially designed with deep fin construction, this fan ensures higher airflow and provides adequate cooling to the motor.

This specially designed cooling system ensures trouble free running of the Shamruthi Induction motors, thereby prolonging the life of the motor.

Fan and Fan Cowl

Our eye for details has been to it that Poly-propylene or sheet metal fans are fitted to the motor for effective cooling. Not only this, the Fan cowls are heavy gauge pressed making them reliable under all conditions. Steel construction securely bolts the motor and shield making them extra rugged and fit for all types of industrial applications.
