Abstract


This paper presents a design of a wireless control for an induction motor. The design was actualized basically using diodes, capacitors, resistors, transistors, transformer, relays, voltage regulator, microcontroller, GSM module and wi–fi module. The design involves using a combination of four IN4007 diodes to form a bridge rectifier. The voltage regulator was used to provide an output DC voltage that remains constant irrespective of load variations or changes in input AC voltage. The microcontroller performs the task of receiving commands from the user’s PC via the wi-fi module or GSM module. The switching section performs the function of switching the regulator to various speed level. To effectively vary the speed of the motor, the maximum distance cover for the wi-fi is 100M, while for the GSM any range as long as there is network service provider. The design performance under test was found to be satisfactory. The design of a wireless control system is one approach to tackle the various problems associated with a wired control system.
