An electric current will flow through a fish if a detectable potential difference exists between one end of it and the other, and the larger the voltage the greater the current flow. Get price

Calculations

In our example input electrical power of the motor is 0.22 A x 6 V = 1.32 W, output mechanical power is 1000 rpm x 2 x 3.14 x 0.00126 N•m /60 = 0.132 W. Motor torque changes with the speed. At no load you have maximum speed and zero torque. Load adds mechanical resistance. Get price
