Varispeed AC drives from L&T are rugged, reliable and easily adaptable to a variety of applications like Fan, Pump, Compressor, Conveyor and many more. Available upto 6000kVA, our drives with flux vector control provides enhanced performance and substantial energy savings have been achieved by various users. Our Drives are designed for optimal efficiency and productivity and are known for their ease of use, compactness, robustness & other powerful features.

The microprocessor based AC variable speed drive, controls the speed of the Ring Frame main motor steplessly and smoothly. It generates different speed-time patterns needed for optimum spinning time and reduction of wastage. Test prove that Texverter gives 7-10% increased production over conventional methods, and dramatically improves yarn quality

The primary elements of POWERMAG eddy current variable speed drive are an AC motor, an eddy current clutch, a tacho generator and a seperate small solid-state electronic controller. The eddy current clutch consists of two rotating members : a drum driven at constant speed by the AC motor and within the drum, a rotor output shaft which connected to the load. Torque is transmitted from the drum to the rotor shaft through an adjustable magnetic field that attracts the two members. The magnetic field is produced by a clutch coil typically below 2% of the total drive power requirements which means smaller and longer - life controller circuits can be used.

The need for a dynamic load system which allows flexibility of appliations in an economical way has been felt for a long time in technical education institutes, research and development, quality control in industry, and "POWERMAG" eddy current adjustable dynamometer provides the ideal solution for such applications.

Tachogenerator is a device which generates an electrical output directly proportional to the shaft speed. The voltage thus generated is fed to a speedometer for speed measurement andor used as feed - back signal for controlling the speed of a rotating machine equipment. In every automatic control system, since the system performance is directly related to the performance it becomes essential that the

In normal injection moulding machines the main motor operates at maximum rated speed and hence the hydraulic pump coupled to the motor deliver maximum flow of oil. This full flow of oil cannot be utilized in process and therefore it is controlled by hydraulic valve so that partial amount of oil is utilized during process and the remaining oil is reverted back and hence the power consumption unit hour will be in higher side.
