We Offer D.c. Motor Study Usefull in Control Laboratory Experiment. a D.c. Motor is Commonly Used as An Actuator in Many Industrial Control Applications Because of Its Features Large Torque and Ease of Speed Variation. the Dynamic Characteristics of such a System Therefore Depends On the Motor Parameters, Viz., Moment of Inertia, Coefficient of Friction, Time Constant and also the Resistance and Inductance of the Control Winding. It is Therefore Important to Experimentally Determine the Mechanical and Electrical Parameters of the D.c. Motor and also to Evaluate Its Transfer Function. the Present Unit is Designed to Study a Small Permanent Magnet D.c. Motor. a Still Smaller Generator Directly Coupled to the Motor is Used for the Dual Purposes of Speed Signal Pick Up and Providing Electrical Loading. the Shaft Speed in Rpm is Displayed Automatically On a 4-digit Panel Meter. When the Motor is Suddenly Switched On, a Novel Circuit Computes and Displays the Time Constant in Milliseconds On a 3-digit Panel Meter. this Avoids the Need for An Expensive Storage Cro. the Motor Unit is Housed in a Cabinet with Transparent Panels, Providing a Good View of the Mechanical System. highlights of Equipment: Torque-speed CharacteristicsDetermination of Motor Parameters - Inertia and FrictionDigital Display of Time ConstantTransfer Function Evaluation experiments: Determination of Torque-speed CharacteristicsEvaluation of Inertia and Friction Parameters Determination of Back E.m.f.

Digital Control System

Min. Order (MOQ) 1 Piece(s)

We offer Digital COntrol Syste usefull for control laboratory experiment. In the present unit a second order transfer function, simulated with operational amplifiers and passive components, has been chosen as the process to be controlled. This results in a well behaved and near perfect linear process which gives a highly predictable performance. The digital controller consists of a 8085 based microprocessor kit with analog-to-digital and digital-to-analog interface. Software supplied with the system resides in a 8K EPROM. This consists of P, PI and PID algorithms in which the three gains may be selected out of 16 levels each. Further, the user may write his own programs to implement additional algorithms and study their responses. Highlights of the equipment: Digital Controller implementation on mP-kitSimple Op-amp based analog plantCRO display of responseDesign and test new algorithms Experiment: Identification of the controlled processStudy of sampling period variationDesigning P, PI, PD and PID controllersAdvanced algorithms implementation Features and Specifications: Second order simulated process (analog process)Built-in D/A and A/D circuits (8-bit)8085 based mP kit as digital controller with user software in 8K EPROM16-bit arithmetic for algorithmic calculations.Square wave test input (internal)16 built-in levels of P, I and D gains each.Complete flexibility for the user to develop own softwareIC regulated internal built-in power suppliesDetailed literature and patch cords includedEssential accessory - a CRO The experiment is complete in all respect.
