Starter Motor Armature Definition. An armature in a starter motor is the part that rotates. It consists of windings, an iron core supported on a shaft, and a commutator. You cannot see the armature without disassembling the motor. However, you can feel its working when the motor spins to crank your car's engine.

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.
Mainly used in large high-power and high-speed applications such as pumps, fans, compressors, main marine drives, extruders and rolling mills, shaft generators, boiler feed pumps, wire rod mills, starting generators, pump storage and starting applications (e.g., blast furnaces).
PIONEER ELECTRICAL WORKS stands for consistent high quality and continuous development. DNA of PEW is Research, Design, Development and successful Deployment. Our philosophy is to deliver a full service solution in Liquid Resistance Starters, Grid Resistance Speed Regulators, Neutral Grounding Resistors and other Power Resistors.
LRS or liquid resistance starter is another type of slip ring induction motor resistance starter.It eliminates the disadvantages of Grid resistance starter a...
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.
insulation resistance should be investigated. Precautions are taken by the factory to guard against corrosion. The machined parts are coated to prevent rust during shipment. If the equipment is to be stored, examine the machined parts carefully for rust and moisture and recoat where necessary.
The form of the resistance is where ρ is the air density, A the crosssectional area, and C is a numerical drag coefficient. The drag coefficient C is 0.5 for a spherical object and can reach 2 for irregularly shaped objects according to Serway.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

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 ...
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.
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.
