We are manufacturing Mechanical Variable Speed Drives in two different designs i.e.one is compact integral design having 0.37 KW to 2,2 KW capacity & speed range we can give is from 0.1 to 500 RPM having ratios 5:1 or max.6:1. Our this compact Mechanical variable speed drive is working on constant HP basis. The drive can be used with Flame proof motors also for using in hazardous area & speed of the Mechanical variable speed drive can be varied through a know provided on the drive itself & by moving knob you Can get required speed variation steplessly. The assembly is made very compact & we can give Helical gearboxes, Mechanical variable speed drives & electric motors integrally fitted in line design. The drive is maintenance free & provided with life time lubrication.
We are also manufacturing Mechanical variable speed drives ranging from 1.5 KW to 45 KW in C or Z design giving speed variation from 7.1 ratio to max. Our this design is simple motorized ,robust mechanical variable speed drive giving speed variation steplessly. The unit is manufactured from quality components & comprises of AC sq.cage motor, variable speed drive unit & helical gearbox with case hardened profile ground helical gears. This unit is very compact & can be supplied for using in horizontal & vertical design. The speed variation can be achieved by means of hand wheel provided on the drive itself.
Our Mechanical tpe infinitely Variable Speed Drives, covering range from 0.5 HP to 5 HP and capable of giving wide output speed range Ratio 5:1
DRIVES FEATURES : Motor and Gear Reducer are integrally fitted to the Variable Speed Drive making it compact single unit.
ADVANTAGES OF VARIABLE SPEED DRIVES :
1) More Torque with a No. of Speed.
2) Fine adjustment od Speed with a dial indicator.
3) Less Maintainance Cost because the use of high quality friction ring.
4) No damage to unit when friction ring wears out.
5) Handle can be fitted in I, II & III position.
6) Can be mounted in Horizontal and Vertical position.
7) Compact constructions.
GENERAL SPECIFICATIONS : We all are aware that 3 phase & single phase Induction motors are the first choice of industriesbut for variable speed drive application, induction motors were not suitable till recent years. We have now developed 3 phase as well as single phase inverters for 3 phase as well as single phase induction motors to suit its characteristics for variable speed application i.e; it keeps voltage to frequency ratio constant and O/P. voltage is modulated sine wave to reduce harmonics. The speed of induction motor is varied by varying the frequency as per formula.
Smooth speed control from min. to mix. RPM with guaranteed torque. Speed regulation better than 1%.
High efficiency more than 95% maintained throughout the speed range. Reverse forward facility.
High starting torque.
Dynamic braking and other special features can be incorporated.
APPLICATION : Our variable frequency A.C. Drives finds application in various industries like – Plastic, Rubber, Textile, Machine Tools, PaperCement, Printing, Wire Drawing, Cables, Pharmaceuticals, Leather, Rolling Mill, Synthetic yarn etc.
GUARANTEE : Our variable frequency A.C.Drives are guaranteed Against any inherent manufacturing defect for a Period of one years from the date of delivery.
GPTEC consists of a totally enclosed, fan cooled (TEFC), flange type three-phase squirrel cage induction motor is mounted on to an eddy current cluth, having a projected, self-ventilated common frame design. There is no physical contact between motor and clutch. This results in smooth response, there by eliminating shock loading and extending equipment life.
GPTEC eddy current variable speed drive operates on AC power supply and provides constant torque at variable speeds over a wide range.
15 kW to 110 kW Integral Design : Our Integral design Eddy Current type A.C.Variable speed drives consists of a totally enclosed ,fan cooled (TEFC) , flange type three phase sq.cage induction motor is mounted on to an eddy current clutch, having a projected .self ventilated common frame design. There is no physical contact between motor and clutch. This results in smooth response, there by eliminating shock loading and extending equipment life.
Our Eddy Current Variable speed drive operates on AC power supply and provides constant torque at variable speeds over a wide range
Our Eddy Current Variable speed drives are being produced in modern and well equipped factory adopting latest techniques in designing and developing the drives , rigid quality control at almost all stages of production and latest testing facilities as per various National & International standards & have helped in raising the image of our Eddy current drives as a quality product making them acceptable to the various prestigious applications throughout the country.
Our Eddy Current variable speed drives are economical and widely used for various Industrial applications like.. Plastic, Rubber, Textile, Machine Tools, Paper, Printing, Wire drawing, Cables Pharmaceutical Leather, Rolling Mill, Synthetic Yarn etc.
Our Eddy Current Variable Speed Drives are available in the size ranging from 0.2 KW to 90 KW & speed variation you can get Is from 120 to 1200 RPM at constant torque basis.
Modular Design :In modular design, we are offering an independent eddy current coupling with input and output shafts. The input can be driven from a standard foot mounted induction motor suitably arranged on a common bed-plate.
This is a versatile design in which the motor can be mounted in-line, alongside on top of coupling.
Modifications :Standard type GPTEC footmounted self-ventilated aircooled eddy current variable speed drives may be furnished with.
Fin-cooled, Water-cooled enclosures
Built in electromagnetic brake
