By pairing Alva’s low-cogging, high-efficiency motors with Elmo’s compact, high-performance drives, system designers can achieve superior control and responsiveness even in demanding applications. The tested configurations showed strong alignment in terms of power, control accuracy, and functional safety - making them a robust choice for motion systems that require both precision and dependability.
The table below summarizes the compatibility between Alva’s motors and ELMO’s motor drives. It highlights which drive models are best suited for each motor, helping engineers and system designers quickly identify the optimal motor-drive combination for applications that demand precision, smooth control, and reliable performance.
Below is an overview of ELMO’s motor drive models, highlighting their key features, communication interfaces, and typical use cases. This guide is intended to help engineers understand the differences between the drives and choose the right model for their application when paired with Alva’s motors.
Platinum Harmonica
A high-power, ultra-compact servo drive featuring full functional safety. It delivers up to 50 A / 100 V (continuous) or 35 A / 200 V, with 100 A peak at 100 V, all in a slim, high-intelligence package. Equipped with EtherCAT communication, safety integration (SIL-3, Cat4 PL-e, FSoE), multiple safe I/Os, and strong motion control capability.
Platinum Whistle
A miniature yet powerful member of the Platinum series. Up to 25 A / 100 V (9 A at 200 V), delivering up to 2 kW continuous (4 kW peak). Despite its small size, it integrates full functional safety, safety-over-EtherCAT, and optional safe I/O. Touches all major highlights of the Platinum series: lightning-fast networking, high processing, and flexible feedback support.
Titanium Solo Castanet
Part of Elmo’s next-generation Titanium lineup, this is a dual-axis, functional-safety-ready servo drive using GaN power switching technology—optimized for low DC voltage applications. Offers up to 15 A at 100 V and 2.4 kW continuous, and is slated for release in 2025.
