New technology makes PacDrive™ SH Series smaller, quieter, smoother running, longer life, more cost effective and powerful.ELAU’s new SH Series servomotors add value to packaging machinery using the PacDrive™ automation system through salient pole winding technology. They are purpose built, designed specifically for the dynamic and environmental requirements of the latest generation of mechatronic packaging machine design.The new designs utilize salient pole winding technology for motors that are more compact and cost effective, smoother running, with higher power density, nearly 50% lower rotor inertia, low cogging torque, quieter operation and higher resistance to winding damage. The new winding design results in a symmetric magnetic field distribution that eliminates magnetic interference on the rotors, resulting in up to 140% longer life. Length is reduced by 30%, Windings are epoxy encapsulated for increased heat dissipation, mechanical integrity, torque production, and resistance to shock, vibration and moisture.They are available from 0.5 to 90 nm (144 nm when fan cooled) continuous holding torques, in 55, 70, 100, 140 and 205 mm flange sizes. Development of barrel-type connectors of equivalent quality to junction boxes results in faster mounting, inherent protection against reversing the polarity of the connections, 310° connector rotation for mounting flexibility, IP67 protection for the connections, and easier motor replacement in the field. Motors and cables are CE/cUL/UL certified.Various shaft configurations, cooling, feedback and shaft sealing options are offered, including a permanent magnet holding brake, shaft key, IP 65 rated Viton® shaft seal, IP 67 rated barrier pressure system, external fan cooling, water cooling, and single or multiturn SinCos encoder.As with other components of the PacDrive family, the new motors are backward compatible, an important practical consideration. The new motors are compatible with existing PacDrive installations, including the same mounting flange dimensions, PacDrive MC-4 digital drives ranging from 5 to 50 amps continuous output, and all PacDrive MAx-4, C and P Series automation controllers.The new motors continue to feature ELAU’s smart nameplate technology, allowing the servo drive to read a chip embedded in the motor and self-configure, simplifying both startup and motor replacement. The drive will automatically adjust to a motor with different characteristics than the original, reducing the amount of spares stock required for a given machine.About ELAUELAU, a company of $12 billion Schneider Electric, equips over $1 billion worth of the world’s best machines annually. Currently over 30,000 PacDrive systems are deployed in packaging machinery worldwide. PacDrive is the first truly integrated automation architecture, capable of performing the functions of PLC, motion control, robotics, temperature control, PLS, MES data interface and more in a single, standards-based software environment.
