Detailed Information:

Ratna Exports strives to develop durable, long-lasting products for diverse industrial applications. Our products are dimensionally accurate and offer outstanding usability. We ensure customer service is our biggest asset and do our best to provide the best services. We assess our clients for their product selection.

As a manufacturer, trader, stockist, supplier, and exporter of Rotor Shafts, we are a rotary component with a cylindrical shape that is used to hold blades and the rotor head in place to produce a rotating component. In addition to nickel rotor shafts for generators for turbines working at high, medium, and low pressures, we also make Stainless Steel Generator Rotor Shafts that are suitable for use in power plants, as they can withstand extreme rotation and pressure levels without becoming damaged.

As a leading supplier of heavy-duty Alloy Steel Rotor Shafts, we supply these to cement and mining companies for grinding and separating materials. Machine parts and shipbuilding companies also require Carbon Steel Rotor Shafts.

A rotor shaft is an essential component of an electric motor, as it sits on top of the laminated core of the rotor and is the transmission shaft that transfers the electrically induced torque to the shaft via the corresponding positive connection, which is associated with the transmission.

 In addition to the requirement for bearing the rotor and the various attachments, the design of the rotor shaft also has a great deal to do with its cooling concept. Additionally, the design of the rotor shaft is very much dependent on the choice of cooling concept for the electric motor. As an electric motor gets more extensive and longer and a more significant and longer rotor shaft, it becomes easier to design new cooling and lightweight components with a hollow shaft. 

Rotor shafts are exposed to very high loads because of their high rotation speeds and high torques up to over 20.000 rpm. However, the transmission is the most crucial component of moving the vehicle by transmitting torque from electrical to kinetic energy. It is, therefore, necessary to design strong and lightweight components to meet these requirements.
