After joining in DIC ,I have to get my first project is biological stirrer.
Objective-
The main objective of designing a stirrer is to make a liquid broth for the compost.
Technical parameters for overhead stirrer-

| Speed range(at 50-60 Hz) | 60-2000 rpm/72-2400 rpm |
| Maximum torque at starting shaft | 150 N-cm |
| Chuck range | 0.5-10 mm |
| Permissible ambient temperature | 5-40 degree-Celsius |
| Permissible relative moisture | 80 % |
| Voltage | 220-240 v |
| frequency | 50/60 Hz |
Stirrer motor-
Stirrer motor torque range-
