SIMULATION AND CONSTRUCTION OF A 180-200 VDC MOTOR CONTROLER

With the advancement in drive technology,electric motors have experienceed an expansion in their touring region (from 20% to about 80%) . The direct consequence of this, is the need for ―soft‖ control of motors, especially dc motors.A laboratory dc motor controller has been designed and constructed in this study. The scope covers the simulation and construction of a microcontroller-based variable speed laboratory dc motor controller with LCD visual indication. The methodology adopted employs the use of traditional calculations to develop models, selection of various component parameters and final fabrication.The heart of the design is the Arduino Microcontroller; ARTMEGA 328P (UNO board). It is configured into proteus is schematic capture and simulation. Tests carried out indicate a fair level of conformity with industry standards. It is recommended that additional circuitry be implemented to enable remote sensing and status monitoring in conjunction with Supervisory Control and Data Acquisition.
