... Pin 1 of the SN754410 is the enable input (abbreviated EN1) for channels 1 and 2 (see Figure 6). When pin 1 is taken to logic high, the pair of push-pull channels (IN1/OUT1 and IN2/OUT2) is “enabled”, meaning that channels 1 and 2 are made operational. Thus, if a logic high is applied to pin 1 (In 1 ...

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.
