The driven "or friction" plate runs on a splined input shaft, through which the power is transmitted to the gearbox. The plate has friction linings, similar to brake linings, on both its faces. This allows the drive to be taken up smoothly when the clutch is engaged. When the clutch is disengaged "pedal depressed", an arm pushes a release bearing against the centre of the diaphragm spring which releases the clamping pressure. The outer part of the pressure plate, which has a large friction surface, then no longer clamps the driven plate to the flywheel, so the transmission of power is interrupted and gears can be changed.

STARTER SOLENOID "Relay" — All cars are wired so that the batterys main cable connects to the starter motor windings "the thick cable is needed for large current flow, right?". This wire must be switched on and off, of course, and it would be costly and inefficient to route it through the ignition switch "not to mention the size of the switchs components required to carry such current!". Consequently, a relay is necessary.

The pulses have a different meaning. The pulses describe a spot to go to. Within the servo there is a feedback mechanism that counts shadows or turns a variable resistor. The servo circuit board then moves the servo to that spot. It knows when it has reached the spot when a certain number of shadows have past or when the resistance reaches a certain value. The arduino has to keep sending the same position over and over again to hold the motor in a current spot. Short pulses go one direction, long pulses the opposite direction, medium pulse widths go to the middle. Middle is typically 1.5 milli seconds.

Solder the wires together so that they cannot be pulled apart, using only a little solder to avoid making the joint bulky. Wind insulating tape in a spiral over the joint.

Before you disconnect anything, make absolutely sure you know how to put it back. Number both sides of each connection with labels made of masking tape. If necessary, make drawings of cable routes and how clips fit. Use a craft knife or razor blade to cut away the wrapping from the damaged section. Take care not to cut into the plastic cable insulation.

Magnets are attached on the inside of the can that spins with the shaft .. sort of like a spinning umbrella. All brushless motors have a spinning umbrella. Inside the umbrella is a permanent magnet. It looks like one continuous round magnet. However it is more like series of magnets.

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."

A stepper motor is a polyphase AC synchronous motor (see Theory below), and it is ideally driven by sinusoidal current. A full-step waveform is a gross approximation of a sinusoid, and is the reason why the motor exhibits so much vibration. Various drive techniques have been developed to better approximate a sinusoidal drive waveform: these are half stepping and microstepping.
