Jyoti has pioneered in the development of Rotating Electrical Machines for more  than fifty years. They include :

Alternators/ Generators
Alternators/ Generators have been significantly contributing to the core sector of power generation. L.T. Alternators - Self Excited Self Regulated (SESR) and Brush-less are coupled to diesel and gas engines as well as to steam or hydel turbines.

• There are special alternators for Navy & Marine alternators.

• Alternators with special design for thyristor load upto 60%.

• Special design for telecom installations.

H.T. Alternators are developed for captive power generation. They are working in parallel with grid systems and are coupled to D.G. Sets.

Large number of Alternators are serving in  the process industries. More than 55% of sugar industries in India meet their captive power requirements through 'Jyoti' alternators.

The Hydro Generators are serving Mini/Micro Hydel Stations to generate power from water falls . They are specially built to withstand high run-away speeds based on turbine characteristics.

Medium and High Voltage Motors
A wide range of medium voltage Motors (Slip-ring and squirrel cage Induction Motors) provide a drive to number of fluid, air handling, material handling, mines, sugar industries equipment.

High Tension Motors are installed at Thermal and Nuclear Power Plants, Core Industries and Water Supply & Irrigation Projects.

Special Purpose Rotating Electrical Machines
Jyoti has developed special purpose rotating electrical machines, custom-built to meet specific requirements of users. For Indian Railways, Asia's largest Rail network, Jyoti pioneered the development of Amo Convertors for single to three phase conversion in A.C. electric locomotives.

Similarly there are Frequency Convertors for 50 Hz. to 60 Hz conversion for repairs on berthed ships and for 50 Hz to 150 Hz for Rayon industries, transformer testing etc. Further, 150/200HZ M.G. sets for Transformer Testing are also developed.

Sugar Industry has a long association with Jyoti. 'Jyoti' multi-speed sugar centrifuge motors are serving 60% of sugar factories in India.

There are two-speed pole amplitude modulated (PAM) motors for energy conservation.  They achieve dual speeds with single winding. They are suitable for a wide range of fluid and air handling equipment.

Generators for Wind Turbines
In the non-conventional energy area Jyoti created major niche by developing Induction Generators for Wind Turbines to generate power by using wind energy.

Largest Rating Vertical Motors for Lift-Irrigation Schemes
Jyoti has successfully designed, engineered, manufactured and tested  [In- House]   the Largest rating Vertical Motor of rating :  2250 kW  ( 3000hp) 6600 Volts, 595 r.p.m. (10-Pole), Vertical -Mounting with Closed -Air- Circuit - Air - Cooled (C.A.C.A.) Motors for Lift-Irrigation Schemes.

THIS IS THE LARGEST RATING MOTOR DEVELOPED IN-HOUSE,  BY  JYOTI  LIMITED .

The motor was rigorously tested for all operating parameters as per  Indian Standards IS: 325, IS: 4029, International Standard IEEE 112 and Japanese Standard  JEC - 37  and found to comply all the technical parameters . 

Latest Design- Techniques were resorted to achieve Energy-Efficient design combined with  low -noise and vibration levels. Optimization of material content and minimum process time are the main ingredients of the design philosophy. Improvement in assembly, tolerances and clearances were achieved through latest state-of-art softwares like Pro/Engineer.

It is an exciting event for Jyoti to achieve the success as “FIRST - TIME -PASS” WITH  “ZERO DEFFECT”.

Jyoti  Limited bagged  order for sixteen motors of the above rating , for Major Lift - Irrigation   Schemes, in Southern India.
