Characteristic Impedance Measurement
... Signal reflection and distortion can be avoided between cables by matching their impedances to each other. The NIM1 standard requires that all input and output device impedances and cables impedances be 50 ohms. But there are times when two cables or devices of two different impedances need to ...

Stepper motor
A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
