Making repairs to the loom Use a circuit tester to check if single wires are damaged. The wiring loom itself seldom goes wrong, but after other repairs have been made, a cable may be trapped and its insulation cut through, causing a short circuit.

The motor that drives the paper path in laser printers is brushless. They are build differently than servo or brushed motors. There are no places where metal is rubbing against metal. Brushless motors will last longer, spin faster, help batteries last longer. They have three wires instead of two. There are two types: inrunner and outrunner.

Fixed speed motors have a cable that contains power, inputs (motor on, motor half speed) and an output pulse related to the motors motion. Variable speed motors typically have no circuitry directly associated with the motor. Instead there are typically three wires coming out that attach to an "Electronic Speed Controller."

Resistance between common wire and coil-end wire is always half of the resistance between coil-end wires. This is because there is twice the length of coil between the ends and only half from center (common wire) to the end. A quick way to determine if the stepper motor is working is to short circuit every two pairs and try turning the shaft. Whenever a higher than normal resistance is felt, it indicates that the circuit to the particular winding is closed and that the phase is working.

The three wires of brushless can be thought of as 1, 2 and 3. Going forward would be this sequence 1-2, 2-3, 3-1, 1-2, etc. Going backwards would be 1-3, 3-2, 2-1, 1-3, etc. What this means is that one third of the motor is helping maintain momentum while another third is pulling the motor in a new direction.

When implementing a real-time system, we find a circular buffer critical whether we are using a DSP processor or a general purpose processor (GPP). However, with a GPP we may have to implement the circular buffer in software. As discussed in the previous section, with each new sample, we have to update the pointer which contains the address of the newest sample. With a circular buffer implemented in software, the programmer needs to take care of updating the buffer pointers after each read and write operation. When the pointer reaches the end of the buffer, the program must wrap the pointer back to the beginning of the buffer.

Before cutting out damaged wires, make sure that the colour coding is the same at each end of the damaged section of each wire, and that it is not so discoloured that it is unrecognisable. If there is any chance of confusion, label both ends.
By Fleurette Nina. Motor Wiring. Published at Saturday, December 30th 2017, 23:49:44 PM. Brushless outrunners are always built on a circuit board. This makes them cheaper. The circuit board for this CD motor has no electronics on it. A ribbon cable attaches 11 wires to another controller circuit board. But often the controller is built onto the same circuit board. The circuit boards interface with a controller in two ways.
