angular contact ball bearings or deep groove ball bearings. In back-up rolls for large four-high strip mills and foil mills, a deep groove ball bearing is often sufficient as an axial bearing, Figure 9. It generally has the same section height as the radial cylindrical roller bearing to which it is assigned. In place of the deep groove ball

AOIP starters for slipring motors, also named electrolytic starters or Liquid Resistance Starters (LRS), use mobile electrolytic resistances. Each starter is made of 3 tanks (one per phase) filled with conductive liquid named electrolyte (water mixed with salt, usually Sodium Carbonate) and two immerged electrodes.
CHEMICAL RESISTANCE DATA These recommendations are based upon information from material suppliers and careful examination of available published information and are believed to be accurate. However, since the resistance of metals, plastics and elastomers can be affected by concentration, temperature, presence of other chemicals and other factors.
The lotus effect, also known as superhydrophobicity, is a term that refers to extremely water-repellant and self-cleaning properties in leaves and plants. Nanotechnology brings effects that occur in nature to a commercial scale--for example, the lotus effect: nanocoated fabrics or paints that are water- and dirt-repellent, just like the lotus ...
Liquid Resistance Starter. These are used for inserting external resistance in the rotor - circuit of slip ring induction motor at the starting to reduce starting - current and increase starting - torque. used in various industries and installations like : cement plants, rolling mills, pumping plants, sugar mills, paper plants. we manufacture & supply liquid rotor resistances with both …

HYDAC is a proven partner and supplier of a modular series ...
The disadvantage of the soft starter technology compared to the frequency converter is that it is unable to control the speed and is unsuitable for applications requiring speed control. When starting loads with high inertial torque, for example in ball mills, it is easily applicable and has to be selected at a higher power level.
The force resisting the motion of a rolling body on a surface is known as rolling friction. The friction depends on the load, diameter of the rolling object, and surface area of the object. Rolling of bike wheels and car tires are the examples of rolling friction.
LRS for large motors, up to 12MW. Pioneer Electrical Works, started manufacturing slipring motor starters, in a modest way, in 1967. Nearely a quarter century later, PIONEER has for the first time in india, manufactured 5000 kW liquid resistance slip ring motor rheostats. Products developed at PIONEER must represent genuine technical advance.
What is carbon black? A vital component in making many of the products we use every day stronger, deeper in color and longer lasting, carbon black in its pure form is a fine black powder, essentially composed of elemental carbon. It is produced by partial burning and pyrolysis of low-value oil residues at high temperatures under controlled ...
Buoyant Force. Buoyancy is the tendency of an object to float in a fluid. All liquids and gases in the presence of gravity exert an upward force known as the buoyant force on any object immersed in them. Buoyancy results from the differences in pressure acting on opposite sides of an object immersed in a static fluid.

120A to the starter motor. The potential difference between the battery terminals [terminal pd] drops at this time to 8.4 V due to the internal resistance of the battery. (a) Explain, in terms of energy, (i) what is meant by 'an emf of 12.0 V', [2] (ii) why the terminal pd drops when the battery supplies a current. [1]
The magnitude of starting torque can be controlled by resistance values; the number of starting steps vary depending upon peak torque limitations required by application. For example, a conveyor drive would have more starting steps than a ball mill. Single starting times can be set by timers, PLC control or tacho feed back.
