With a total of 2 patents to his name, Rafflenbeul has developed innovative solutions that enhance efficiency and functionality in various applications.
Latest Patents
Rafflenbeul's latest patents include a Yarn Winding Apparatus and a Frequency Inverting Apparatus. The Yarn Winding Apparatus is designed for winding multiple continuously advancing yarns into cross wound packages. It features a rotatable revolver that mounts a pair of winding spindles, which are alternately moved between winding and doffing positions. Additionally, a beam-like carrier supports a yarn traversing mechanism and a sensor roll for each package being formed. The drive and control electronics are integrated into a control unit mounted on the outer end of the carrier.
The Frequency Inverting Apparatus is engineered to drive multiple motors at varying speeds. It includes a rectifier that supplies direct current power to a DC bus circuit. A series of inverters connected to the DC bus circuit each drive a respective motor, with individual controllers managing the frequency of the output to control motor speed. This design allows for a more efficient use of power, as the rectifier and DC bus circuit can be sized to handle less than the total maximum loads of all motors.
