HawkeyePedershaab has introduced the new series of ePak Packerhead Machines. Designed from the ground up, the ePak machine and its associated technology represent a major leap forward in packerhead production technology. At the center of the new technology is the machine’s revolutionary eDrive rollerhead drive system. Powered by a proprietary, gearless, direct-drive, 60-pole, brushless permanent magnet motor, the eDrive provides major operating benefits as compared to industry standard hydraulic or asynchronous electric drives. The eDrive’s permanent magnet motor develops much higher torque density and has a wider torque/speed operating band - allowing precise packing control throughout the machine’s entire production range. All the supplied electrical energy is used for generating the stator torque active magnetic flux which further enhances speed and torque control. Additionally, the operating characteristics of the eDrive motor permit rollerhead speeds as low as 90 RPM to be achieved without the need for a gearbox. The ePak’s direct rollerhead drive system improves control, streamlines operation, and eliminates a multitude of expensive wear and maintenance items.
