STARTER MOTOR — This is a powerful electric motor that engages the cars flywheel in order to spin the crankshaft. As in all electric motors, the starter is composed of windings of wire that form loops, ending at the commutator segments "remember these from the generator". The armature coils are mounted on the motors central shaftsupported with bearings and the field coils are formed into four or more "shoes", placed inside the steel frame of the starter.

A servomotor is a specific type of motor that is combined with a rotary encoder or a potentiometer to form a servomechanism. This assembly may in turn form part of another servomechanism. A potentiometer provides a simple analog signal to indicate position, while an encoder provides position and usually speed feedback, which by the use of a PID controller allow more precise control of position and thus faster achievement of a stable position (for a given motor power). Potentiometers are subject to drift when the temperature changes whereas encoders are more stable and accurate.

As the motor rotor turns, a sinusoidal voltage is generated proportional to the speed (step rate). This AC voltage is subtracted from the voltage waveform available to induce a change in the current.

PCBs with SMT on both sides and those with mixed TH and SMTs may start to flex and bow when in the reflow oven or selective soldering machine. For this reason, the maximum size for this type of board is usually smaller than the single-sided. Breaking out the boards manually can stress the board and components near the edges, the solder joints, or leave out rough stubs on the edges

Splices may be used within 30cm of a termination device when attaching to the pigtail spare lead of a potted termination device, to splice multiple wires to a single wire, or to adjust the wire sizes so that they are compatible with the contact crimp barrel sizes.

You can also see that I’ve made it very easy for heat to move away from the regulator (U1) and into the ambient environment or into other portions of the PCB. U1’s thermal tab is connected to a large copper pour, and this copper pour is shot through with vias that conduct heat down to the internal ground plane. If I were really worried about thermal issues I could also connect these vias to a copper pour on the bottom side of the board, but in this case, it would have been total overkill.

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.

The sharp edge of the hole will soon chafe through wire insulation and cause a short circuit. Whenever you pull a connection apart, look for corrosion which might cause bad contact. If necessary, clean contacting metal surfaces with a fine file or emery cloth.
