3 wires
There should be 2 or 3 wires. A hot, a neutral and sometimes a ground.
It depends on the particular DC servo motor. At minimum, you need two wires for power, and two wires (one may be shared) for sensor feedback. Often, there are more wires, particularly involving the sensor. I have seen servos with two power connections, five position (quad-tapped potentiometer) connections, and two velocity connections, and that was 35 years ago - today, things might be different - what with digital encoders and such.
2 wires auv cable, and power cable
There is only one ground wire needed on any motor, single or three phase.
There are three wires supplying power to your home two line wires @ 110 volts each and one nutral.
Usually two cables total. Such as the SATA Cable and the power cable. As for how many wires are in those cables, it would depends on the connection. Such as IDE have 40 wires. Power cables are usually four pin. It all depends.
a usb cable has four wires, two for power and two for communication.
5.5 Litres. Same as conventional motor oil.
Count the number of spark plug wires. There is one for each cylinder.
The formula you are looking for is I = W/E. Then the wire size can be determined so as not to melt the wires.
