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.

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.

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.

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.

The AWG doesn’t have high current requirements, but the board house doesn’t give you a discount for using less copper, so you might as well opt for large (= low-resistance, low-inductance) traces if you have the room.

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.

The outrunner is already the standard motor in laser printers, copy machines, fax machines, scanners, blue ray players, cd players, where a very precise, constant speed is needed. It is also found in model helicopters, RC airplanes and other variable speed applications where there are light weight requirements. It is totally different than all other motors.

It transmits engine power to the gearbox, and allows transmission to be interrupted while a gear is selected to move off from a stationary position, or when gears are changed while the car is moving.

Most cars use a friction clutch operated either by fluid (hydraulic) or, more commonly, by a cable. When a car is moving under power, the clutch is engaged. A pressure plate bolted to the flywheel exerts constant force, by means of a diaphragm spring, on the driven plate. Earlier cars have a series of coil springs at the back of the pressure plate, instead of a diaphragm spring.
