    Basic Information

Technology developed: Variable Speed Solar Based Bageshwari Wool Charkha (TP19768783102)
Category: Product(Hardware/Material/Software)
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Dr. R. P Saini Indian Institute of Technology Roorkee Department of Hydro and Renewable Energy Professor
Technical Application Area: Energy/Power
If 'Other', please specify:
Please give more details of new technical application area:
The modified Bageshwari wool charkha has facilities to be operated by electricity, solar PV system with speed control mechanism and by foot paddle mechanism. For spinning coarse and fine quality yarn, control mechanism has been provided and also a USB socket for battery backup. The charkha is light in weight and its components can be dismantled for easy transport in remote areas and assembled again at site. The modified advanced Bageshwari Wool Charkha version-2 comprises of solar panel (75 W), electric motor (110W), battery (12 V) with 4-volt rechargeable battery operated by the foot pedal. Further, a knob control is provided to adjust for coarse and fine spinning of wool. This system has advantages of a USB socket, battery backup, lightweight structure and its components that can be easily be assembled and disassemble.
Organization(s):
Indian Institute of Technology (IIT) Roorkee
Affiliated Ministry: DST, Govt. of India
Type of technology development: Indigenous
Does the technology help in replacing any import items currently
procured from outside India?
No
Does the technology have export potential? Yes
Category of Technology developed: Export Potential
Stage of Development: Commercialized
Please describe in detail including the TRL Level:
Traditional Bageshwari charkha was modified during the phase-1 in four stages to remove the problems raised by operators. After field trial and feedback received from the spinners, Bageshwari charkha was modified in phase-2. A variable speed solar based modified Bageshwari wool charkha is introduced with speed controller, solar PV, battery, inverter, compact gearbox, mobile charger, control mechanism. To test the performance of the modified Bageshwari charkha, a testing was organized for the artisans of Rajasthan under the direction of RuTAG coordinator. Based on the feedback from artisans and further request for field trial, one set of modified Bageshwari charkha has been sent for field trail for spinning yarn. Five sets of Charkha were fabricated for demonstration in the Uttarakhand and other states.

    Abstract:

Applications: Wool spinning provides the main source of earning particularly for underprivileged public in a given area. Spinning of wool for weaving can boost local livelihoods, as raw wool is easily available and local people are well versed with spinning and weaving. More than 60000 families are involved in hand spinning and weaving in Uttarakhand state and these are directly benefitted.
Advantages: Introduced with 75 Watt of solar panel and motor with 110 Watt and speed can be raised upto 3000rpm. Operated by solar PV system with speed control mechanism while foot operated mechanism is retained. Provided with USB charging port and emergency paddle light.Battery backup has been provided. Control panel for coarse and fine adjustment through which motor RPM can be set in range between 150 to 3000 RPM. Spinner can spin nearly 1.5kg of wool yarn in a day (more than 3 times of traditional charkha).With controlled rotation, better quality of YARN production.Reduced labour and motivation to spinners for more production and earnings.The modified charkha operated electrically using single phase motor of 75 watt consumes only 0.6 unit of electricity in a day by working for 8 hours, which costs about Rs. 2.0 per day.The modified wool charkha would be beneficial to the spinner and for the cottage industry for the production of yarn with local fiber of Uttarakhand and Rajasthan.The charkha is eco-friendly as it does not require any fossil fuel and sort combustion.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work
read more >>

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
