Slip-Ring Motor Starting Panels
Rotor Starter
The Slip-Ring Motor Starters are based on the series of resistors that are applied to the rotor circuit to control the speed/torque characteristics of the motor. Rotor starters are mainly used for the motor starting applications requiring high-starting torque like loaded belt conveyors in mining industry. By external resistors, it is possible to shift the motor maximum (break-down) torque up to starting torque point for motors under heavy loads during start-up. The resistors are splitted into some steps and controlled via contactors by motor starting control system. As the motor speed increases, the external rotor resistors are eliminated by shorting contactors until all external resistors are shorted out.

Flow Indicators
Flow indicator with rotor features a self-cleaning mechanism to ensure full visibility of the rotor at all times. Typical sight flow indicators suffer from poor indicator visibility through normal use from build-up that impedes observation of the rotor through the viewing window. Typically, for a sight flow indicator to be cleaned, it must be removed from the pipeline, cleaned and then replaced at some specified time, such as during plant shutdown. Unfortunately, dirt build-up does not typically schedule itself to correspond with planned shutdowns. Enter the KOBOLD DAA Series flow indicator. Simply twist the sight glass and the integral wipers clean the flow indicator's viewing area to allow unobstructed observation of the rotor. The offending contaminants are then simply washed away by the media flow. This process may be repeated as often as desired with no fuss and no downtime. The DAA is available with brass or stainless steel fittings with " to 1" NPT female threads. The DAA is also available without a rotor for observation of fluid condition.

Crowbar Resistors
Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator. They are used to prevent damage to the inverter circuits attached to rotor side when a fault occurs in the grid. DFIG power converter, which has a restricted over-current limit, needs special attention during faults in the grid. If the rotor current or DC link voltage reaches the threshold value, crowbar resistors disconnect the converter in order to prevent the generator turning into a squirrel cage induction machine. By crowbar resistors, the DFIG could stay connected to the grid and continue its operation.

Turbine Flow Meters
Axial turbine flow meters are designed with wear resistant internal components to provide trouble-free operation and a long service life. Fluid entering the flow meter is first conditioned by the inlet flow straightener which reduces turbulence in the fluid. The moving fluid causes the rotor to spin at a speed that is proportional to its flow rate. As the turbine blades on the rotor pass through the magnetic field of the pickup, an electronic pulse is generated.
