Flexible platform with wireless interface for DC-motor remote control

Abstract

Several portable applications, such as small electric vehicles and power tools, often require the use of direct current (DC) motors that significantly differ from one to another in terms of power, torque, and driving techniques. New market requirements of these applications suggest the implementation of smart user interfaces that may allow the introduction of those devices in the new Internet of Things paradigm by making them connected. This paper discusses the design and verification of a flexible platform able to drive different types of DC motors that is also provided with a Bluetooth connection for remote control and monitoring. As the platform can drive different motors with different driving techniques, it provides standardisation and cost reduction in the production of a set of tools. Two gardening tools are used as case study to verify the design and flexibility of the board. Both tools are successfully controlled and monitored with a wireless connected remote user interface.
