They are placed in a hostile, hot environment and cannot be expected to last indefinitely. Another mode of failure is a shorted or open winding. This exhibits itself as a "dead spot" on the commutator. If a brush lands on a dead spot the motor wont turn at all. A third failure-mode is a faulty pinion engagement. Sometimes the pinion assembly gets stiff or stuck due to lack of lubrication or wear. Starter motor rebuilding or replacement is required for all of these problems.

Electronic motors are found in kids toys, RC cars, airplanes and helicopters, printers, scanners, and fax machines. They are expensive when purchased, quantity 1, new with manual. This is because the motors are part of a supply chain that is usually just making enough to fill orders for kids toys, etc. Many can be found for sale on the internet, but very few are in stock and the price is high if they are. Often it is easier to purchase the kids toy and take it apart. The goal is to connect these motors to the arduino and then make something new with them. The goal of this document is to describe what to expect.

Torque curves may be extended to greater speeds if the stator poles can be reversed more quickly, the limiting factor being a combination of the winding inductance. To overcome the inductance and switch the windings quickly, one must increase the drive voltage. This leads further to the necessity of limiting the current that these high voltages may otherwise induce.

When the clutch pedal is released, the thrust bearing is withdrawn and the diaphragm-spring load once again clamps the driven plate to the flywheel to resume the transmission of power. Some cars have a hydraulically operated clutch. Pressure on the clutch pedal inside the car activates a piston in a master cylinder, which transmits the pressure through a fluid-filled pipe to a slave cylinder mounted on the clutch housing. The slave-cylinder piston is connected to the clutch release arm.

Generally, the fixture materials, which range from synthetic plastics and stones to aluminum alloys and epoxy glass, should be electrostatic neutral, and able to withstand repeated thermal cycles and chemicals without deforming or wear. In particular, the thin fixtures provide better thermal management.

When the plunger is pulled into the coil all the way, the pinion fully engages the ring gear. When the ring gear is fully engaged, engine cranking begins. When the engine starts the hold-in coil will cut out and the plunger will move out, retracting the pinion and opening the starter switch.

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 damage caused by overheated wires is easy to find; but if only a single wire has overheated and melted at some point, you may have to use a circuit tester to find the break. If the damage is in an open run of wiring, you may be able to mend separate wires without taking out a section of the loom. If it is in any part of the covered sections, you need to remove at least part of the wiring loom.
