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.

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.

The arduino can also supply power to the motor, but normally this is only a good idea for demonstration purposes. The arduino has a very weak power supply, and attempting to power a motor through it can destroy the arduino. Furthermore, the arduino may not be able to supply the exact correct maximum voltage. For this reason, an ESC is placed between the arduino and the motor.

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.

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.

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.

However, and this is very perplexing, there is no additional information related to the "separate application note." My suspicion is that Sensirion intended to include a link to this app note but then simply forgot to include it; perhaps additional information will be provided in the datasheet next revision.

A micro controller or stepper motor controller can be used to activate the drive transistors in the right order, and this ease of operation makes unipolar motors popular with hobbyists; they are probably the cheapest way to get precise angular movements. For the experimenter, the windings can be identified by touching the terminal wires together in PM motors. If the terminals of a coil are connected, the shaft becomes harder to turn.
