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.

Some can carry more than one board hence allowing the processing of multiple PCBs simultaneously. Other designs have adjustments to support both the primary and secondary side processes.

This prevents the damage to the PCB or components which can occur due to surface stress and splinter when separating the boards. One drawback with this method is that it may leave some unwanted board protrusions on the edges.

Identical model motors vary, so each needs to be calibrated by banging against some edge ... think of the banging noise when an inkjet printer is turned on. Servo motors are good for robot wheels that have to turn a certain distance then stop. They are good for robots that have to balance themselves somehow. Auto pilots can use these to navigate a hallway. They are not good for spinning propellers like brushed dc motors and brushless motors.

There may be some resistance that feels like removing magnets from each other. Underneath the cup of all outrunner brushless motors is a series of coils. On some motors, between the coils, are hall effect probes. Hall effect probes detect the spinning magnetic field and provide a pulse out of the brushless motors to the electronics. From this pulse the electronics can precisely control the speed of the motor

Most computer controlled DC motors are pulsed. Pulses of a fixed voltage are sent to the motor, usually by an Electronic Speed Controller or ESC. A pulse of 1.5 ms causes no motion. Wider pulses cause faster spinning in one direction. Shorter pulses cause faster spinning in the opposite direction. Eventually, an overstressed ESC stops pulsing and turns one wire on and one wire off, depending on the direction.

There are three wires going to the motor instead of two. The wiring between the ESC and the Arduino consists if the same 5 wires. The three wires give the brushless motors more pulling power. Understanding this helps understand stepper motors below.
