Kollmorgen Corp. has announced an expansion of Kollmorgen IC Ironcore DDL motor family to include support for 400/480 VAC-powered applications, in addition to its existing 230 VAC offerings.
Kollmorgen’s new direct drive linear motor provides continuous and peak forces of 8,211 N and 13,448 N. When operated at higher bus voltages, the motor can maintain its rated force at increased speeds, making it suitable for applications like machine tools, semiconductor manufacturing, battery production and industrial automation where fast and accurate movement of heavy loads is required.
Compact, efficient and scalable machine architecture
In environments with a 400 or 480 VAC bus voltage, the IC Ironcore DDL can reduce or eliminate the need for a transformer that might be required for motors with lower voltage ratings. Additionally, operating at a higher voltage enables the motor to deliver equivalent performance with lower current, which may allow for the use of a more compact drive amplifier and reduced-gauge cabling.
Smaller drives, reduced-gauge cables and the elimination of transformers can contribute to a more compact control cabinet with lower cooling demands. The IC Ironcore DDL motor also includes an optional water-cooling feature that can increase continuous force output by approximately 40–60%, which may enable the use of a smaller motor in some applications. These features can support a more compact and potentially cost-effective machine design, offering practical benefits to OEMs and end users.
Enabling solutions for global customers
The IC Ironcore DDL motor supports international use through its compatibility with 230, 400, and 480 VAC bus voltages—common standards in North America, Europe and Asia. This reduces the need for region-specific machine modifications. UL and CE certifications, along with RoHS and REACH compliance, help facilitate regulatory approval in global markets.
The IC Ironcore DDL motor is part of Kollmorgen’s range of direct drive linear motors, which also includes the ICD Ironcore Low Profile DDL and the IL Ironless DDL. When used with AKD or AKD2G servo drives, these motors are engineered to deliver high levels of precision, smooth motion and reliability in performance-sensitive applications. The AKD2G dual-axis servo drive can synchronize two motors — such as in an x/y table setup — also helping to conserve space within the control cabinet.
