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.

The fixture should support the board and prevent distortion as the board goes through the printing, component placement, and reflow processes. Its construction should ensure adequate protection for the bottom side components during the double-sided reflow process.

The tab-route or breakaway tab method is suitable for PCBs with either similar or different designs, or where it is not possible or practical to use the V-grooves. The designer leaves a perforated tabs routing space between the different or similar boards, hence allowing for separation after processing.

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 stepper motor is known by its property to convert a train of input pulses (typically square wave pulses) into a precisely defined increment in the shaft position. Each pulse moves the shaft through a fixed angle. Stepper motors effectively have multiple "toothed" electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external driver circuit or a micro controller. To make the motor shaft turn, first, one electromagnet is given power, which magnetically attracts the gear teeth. When the gear teeth are aligned to the first electromagnet, they are slightly offset from the next electromagnet.

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.

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.
By Dorian Yannic. Motor Wiring. Published at Sunday, December 31st 2017, 04:44:25 AM. Bipolar motors have a single winding per phase. The current in a winding needs to be reversed in order to reverse a magnetic pole, so the driving circuit must be more complicated, typically with an H-bridge arrangement "however there are several off-the-shelf driver chips available to make this a simple affair". There are two leads per phase, none are common.Static friction effects using an H-bridge have been observed with certain drive topologies.
