Energy harvesting devices for condition monitoring applications of pneumatic combined clutch-brakes

Abstract: In order to reduce unscheduled downtimes and maintenance costs, industrial machinery is being fitted with condition-monitoring systems (CMS) that measure important environmental factors and wear parameters of the machine. The electrical power required by these (often retrofitted) sensor systems can be supplied by energy harvesting devices. Pneumatic clutch-brakes provide an excellent application for both CMS and energy harvesting. These industrial machines transmit mechanical power through Kevlar brake pads which wear out due to the large frictional forces at play. The machine accelerates and decelerates from 0 to 1000 rpm and vice versa within 200 ms. This paper reports on energy harvesting devices that can use the large accelerations of the clutch-brake as an energy source to supply the CMS that measures the temperature and wear of the brake pads. A rotary system generates an average power output of 1.5 mW with the machine performing one clutch-brake action every four seconds
