InSwitch is an ultra-compact, smart electronic device for performance improvement of line-operated, three-phase, induction motors. It is self-powered and can be installed inside the motor terminal box, measuring simultaneously the motor currents, voltages, and mechanical vibration. InSwitch can be used for motor soft-starting, dynamic load-based connection-mode change (leading to 5-15% energy savings in variable-load, fixed-speed motors), advanced motor protection (overload, overcurrent, stall, voltage/current unbalance, and phase loss) and fault diagnosis (combining motor current and vibration data), and remote control/monitoring (embedded wired and wireless communication). This novel device can potentially replace millions of traditional electromechanical contactors and allows the integration of induction motors into “Industry 4.0” data networks. InSwitch concept has been partially developed in ISR-UC, involving MSc and PhD students, and awarded with several national and international innovation prizes, including a 50 k€ funding from the Horizon 2020 – SME Instrument – Phase 1. It has two national patents.
