− | + | =DC - Geared Motor= | |
The DC Geared Motor we use is a combination of 4:4:1 gears and a brushed DC motor. The motor is cylindrical, with a diameter just under 25 mm, D shaped output shaft which is 4 mm in diameter and extends 12.5 mm from the face plate of the gear box. This motor unit weighing 95 gms, has a speed of 1400 RPM d and 150 mAmps Current rating at 6V. | The DC Geared Motor we use is a combination of 4:4:1 gears and a brushed DC motor.

− | + | =Magnets and 3D structure= | |
Neodymium cubic supermagnets of size 5 mm are fitted into a 3D structure on the motor, to create a magnetic field for the fish inside the bioreactor. The 3D structure is a platform to be fitted on the DC motor, having cubical holes to fit the magnets in. | Neodymium cubic supermagnets of size 5 mm are fitted into a 3D structure on the motor, to create a magnetic field for the fish inside the bioreactor.
