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 three wires of brushless can be thought of as 1, 2 and 3. Going forward would be this sequence 1-2, 2-3, 3-1, 1-2, etc. Going backwards would be 1-3, 3-2, 2-1, 1-3, etc. What this means is that one third of the motor is helping maintain momentum while another third is pulling the motor in a new direction.

This means that when the next electromagnet is turned on and the first is turned off, the gear rotates slightly to align with the next one. From there the process is repeated. Each of those rotations is called a "step", with an integer number of steps making a full rotation. In that way, the motor can be turned by a precise angle.

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.

Where they run through a hole, the sharp edges are lined with a rubber grommet. Sometimes the loom is divided into sections joined by multi-pin plugs and sockets, so that it can be removed and refitted section by section.

I think that this approach results in an easier design process and a better board. The AWG layout progresses from left to right: from power input and communication input/output, to the power supply circuitry, to the processor, to the DAC (which is controlled by the processor and constitutes the board’s transition from digital to analog), to the analog signal-conditioning circuitry, and finally to the output connector. Parts that don’t have a specific position in the functional flow—such as the oscillator (U4), the DAC’s passives (C16, R5, etc.), and the voltage reference (U3)—are arranged near the components that they support.

But they can also spin like a DC and Brushless Motor. They can not hold their position as strongly as a servo motor, and they can not spin as fast as a brushed or brushless motor.
