Application Scenarios:In a high-speed packaging machine, a pick-and-place unit requires rapid acceleration and deceleration to transfer products from a conveyor to a tray. The existing standard motor struggles with positioning accuracy, causing misalignment. By upgrading to the 115DUB300CACAC, the system leverages its high torque-to-inertia ratio and 3x peak torque capability (approx. 14.4 Nm) to achieve faster cycle times. The integrated high-resolution encoder provides precise feedback to the paired Unidrive M drive, enabling closed-loop control that eliminates cumulative error and ensures each product is placed with millimeter accuracy, even at speeds exceeding 100 cycles per minute.

Technical Principles and Innovative Values:
- Innovation Point 1: High Dynamic Response with Optimized Rotor Design. The PG115-100 features a low-inertia rotor design combined with high-energy permanent magnets. This engineering balance provides an excellent torque-to-inertia ratio, allowing the motor to achieve extremely fast acceleration and deceleration rates. This is critical for applications like indexing tables or robotic arms where minimizing cycle time is paramount, without sacrificing the smoothness of operation typically associated with larger, slower motors.
- Innovation Point 2: Integrated High-Resolution Feedback System. Unlike standard motors that require external encoders, the 115DUB300CACAC comes with a factory-integrated, high-resolution feedback device (often supporting protocols like Hiperface or EnDat). This “all-in-one” design eliminates alignment issues and backlash associated with separate resolver kits, providing the servo drive with ultra-precise position and velocity data for superior closed-loop control and accurate stopping.
- Innovation Point 3: Industrial Hardened IP65 Construction. The motor’s housing is sealed to IP65 standards, making it resistant to dust and low-pressure water jets. This allows it to be deployed directly on machinery in challenging environments like food processing or pharmaceutical packaging, where washdowns are common, without the need for an additional protective enclosure, simplifying cabinet design and reducing overall system cost.
