We offer Study of Stepper Motor useful for control labs. This experimental set-up aims at providing an exposure to the basic operation of a stepper motor, its drive and logic, and limitations as far as the internal dynamics is concerned. Experiments have been designed to demonstrate the effect of external load inertial and frictional, on the motor performance. Provisions are available for free running operation as well as single stepping mode with LED indication for the active phase. The unit may also be operated by a microprocessor kit for which a built-in interfacing and automatic changeover has been provided. It may be seen that this is a complete experiment set and not a microprocessor kit with an ADD-ON card and a motor. Highlights>>Stepper motor operation through pulse circuit>>Stepper motor operation through 8085 mp kit>>Built-in programs in EPROM>>Dynamic response study Experiments>>Manual stepping through push button switch.
