We are offering stator rotor controller. Interlocking between stator and rotor as per iss: 8544. Offers improvements in reliability as compared to l.r.s. Low maintence; incorporates switching through contactors. Smooth acceleration of the slip-ring induction motor. Reduces electrical and mechanical stresses of the machines. Can be custom designed as per customer’s requirements. The capacity of rotor controller is 15hp to 1000hp. We have applied closed circuit technology in all our stator-rotor controllers for the safe and smooth operation of slip-ring induction motors. Our controllers are built as per iecnema standards meeting the provisions of the national electric safety code. Stator rotor controllers rotor controllers are extensively being used to replace existing manually operated wound rotor starters and liquid rotor starters. The resistances are basically to provide high initial starting torque with low inrush current from mains in applications like high inertiahigh frictional loads and during run-up are bypassed through contractors by timers to shot out final rotor contactor until full speed is attained. The rotor controller provides acceleration to full speed and thus reduces electrical and mechanical stresses in the motor and drive. The resistances incorporated in our rotor controllers are designed in such a manner that they provide a very long term service with zero maintenance. All our rotor controllers are designed to start wide range of motors with strict qa system.

We are offering munnalal pump protector. Provision of starting starter automatically when all the 3phases are available, due to which maximum voltage is always available & will freedom from starting & stopping again-n-again. Due to presence of rubber gasket is completely protected from dust , mud & water. Incoming & outgoing (3phase, multi lock type) terminals are provided separately. Less electricity consumption due to main solid copper wiring (with glass coating & without lungs), entry of incoming & outgoing wires is from the bottom of starter box due to that there is no possibility of entering rain water. Two separate 6 mm bolts (with washer) are provided for earthing. The front door of starter is welded from hinge due to which no panic of falling of door. Rust free due to fully powder coating heavy panel box. No. Possibility of provocation & accident because unable to open starter without tool kit. the capacity of mlpp 1 hp to 10 hp.

We are offering munnalal motor protector. Provision of tripping automatically the starter in case of overload due to which it gives relief from the worry of burning the motor. If there is phase short circuit or eating in starter outgoing, then mcb of starter will trip automatically due to which fault doesn’t multiply. Due to presence of rubber gasket starter is completely protected from dust, mud, water. Incoming & outgoing terminals are provided separately. Less electricity consumption due to main solid copper wiring. Entry of incoming wires is from the bottom of starter box to that there is no possibility of entering rain water. Two separate 6 mm bolts (with washer) are provided for earthing. The front door of starter is welded from hinge due to which no panic of falling of door. Rust free due t fully powder coating heavy panel box. No possibility of provocation & accident because unable to open starter without tool kit. The capacity of mlmp is 1 hp to 10 hp.

We made fully automatic multi step & step less slip-ring motor starters 1 hp up to 1000 hp,which are made as per iecnema standards,incorporating the need for multiple starters as per the customor's requirements.we use rittal enclosures.

We are offering automatic power factor control panels. Syemco manufactures high end power saving products. The brand name of syemco had started the product “automatic power factr control panels” about a decade ago & are now pioneer in achieving power factor to unity. In view of constantly rising power tariff and penalties imposed by the state electricity boards / utility companies, it is imperative for any ht and lt industry of consumer to install a power factor control panel for curtailment of power factor penalty, reducing maximum demand and also save energy and power. Technical features: microprocessor based automatic controller with power display. All major components are of standard makes like, simens, l&t, epcos, neptune etc. All the components are carefully integrated for reliable performance and longer life. Used small correction steps to maintain accurate setting. Contactors (with mcbs or mccbs backup protection) are used to switch on capacitors with spiral conductor design to minimize switching surges. Auto / manual facility. In-built time delay for switching on of a capacitor bank to avoid impulse signal operation. Very low watt losses, capacitors are used. Product range: 20kvar to 1000kvar. Applications: all types of manufacturing units like solvent plants oil mills, ginning & pressing factories, chemical industries, food industries, rice mills, paper mills, fertilizer plants daal mills, steel industries, cement mills, spinning mills etc.

We are offering auto transformer starters controller panel. Motor is connected in delta from the start. Auto transformer provides voltage to the motor at start. Appropriate lower voltage tapping- customized as per the application- is provided to the motor. After the motor has attained significant torque changeover from auto transformer to on line takes place. The changeover is “closed transition” i.e. During changeover the auto transformer acts a choke supplying voltage to motor- hence smooth or stepless or soft starting takes palace. The motor then runs on line current. The transformer is isolated from both the ends to protect the contactors. Adjustable high torque: a high torque (up to 64%) possible and can be customized by voltage taping. No power quality issues: all standards electrical components ensure that there are no harmonics or other power quality issues. Transient elimination: korndorfer closed transition technology ensures that transients are eliminated. Motor protection: motor is connected in delta at the time of starting to avoid high inrush current in the motor winding thus providing lesser heat generation. Reduced voltage starter: voltage controlled by auto transformer at the time of starting. The capacity of ats is 15hp to 1000hp.

We have applied korndorfer closed transition technology advanced with primary -off logic to all our reduced voltage auto-transformer starters. Our starters made as per iecnema standards,oncorporating the need for multiple starters as per the customor's requirements.we use rittal enclosures for our air cooled reduced voltage auto-transformer starters.
