The circular arrangement of electromagnets is divided into groups, each group called a phase, and there is an equal number of electromagnets per group. The number of groups is chosen by the designer of the stepper motor. The electromagnets of each group are interleaved with the electromagnets of other groups to form a uniform pattern of arrangement. For example, if the stepper motor has two groups identified as A or B, and ten electromagnets in total, then the grouping pattern would be ABABABABAB.

This allows them to easily fit the boards in the standard assembly, reflow, or automatic inspection machines. In addition to handling the irregular boards, the technologies enable the simultaneous processing of multiple boards as opposed to working on each board individually, hence reducing the production time and costs.

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.

It’s always a good idea to minimize the length of traces carrying high-frequency digital signals. First of all, there are noise benefits: a shorter, more direct trace reduces the amount of noise that would otherwise be coupled into adjacent traces, and a shorter trace also reduces electromagnetic interference (EMI) because it is less effective as an antenna. The second issue is related to transmission-line effects. Minimizing trace length is a simple way to avoid problems related to signal reflections. However, reflection is not a significant concern at frequencies in the 10 MHz range, unless you are dealing with long interconnections or a very large PCB.

Each of the two methods provides a carrier with standard dimensions and provisions for fitting, securing and supporting the irregular boards.

When implementing a real-time system, we find a circular buffer critical whether we are using a DSP processor or a general purpose processor (GPP). However, with a GPP we may have to implement the circular buffer in software. As discussed in the previous section, with each new sample, we have to update the pointer which contains the address of the newest sample. With a circular buffer implemented in software, the programmer needs to take care of updating the buffer pointers after each read and write operation. When the pointer reaches the end of the buffer, the program must wrap the pointer back to the beginning of the buffer.

The electronics in the ESC pulses the motor to tell it is initial direction and some other feed back system humans using RC or an autopilot reading accelerometers or gyros adjusts the speed.
