Stepper Motor Demonstration Unit with a.3.5 Kg cm Torque Motor 2001A

Categories: Industrial & Power Electronics


ADTRON’S Stepper Motor Demonstration unit is a versatile self – contained stand alone unit useful in the
study and demonstration of the principle and working of a stepper motor with various electronic controls such as
manual switching and Microprocessor based controls. Provision for direct up interface is provided. It consists of two
units viz., stepper motor unit and the translator unit. Each unit is housed in an elegant cabinet with a well spread
intelligently designed circuit layout on the front panel. Multicoloured test points are provided at various stages in the
circuit to observe the waveforms and voltages. It is strongly supported by a comprehensive instruction manual
complete with theory, operating details and machine code program.
