Celera Motion, a business unit of Novanta, has launched what it says is the world’s smallest servo drives, named the Denali Series. The compact, ultra-fast servo drives can be used for a variety of service robots, surgical robots, industrial grippers, and lab automation applications.

The series features two version, the Denali XCR and the Denali NET. The XCR is a miniature, ready-to-use version that enables quick installation and system commissioning. The NET is an ultra-compact, high-power density version of the drive that is pluggable, making it optimal for a carrier board, with single or multi-axis integration. Both versions are available with EtherCAT and CANopen communication protocols and specially optimized for demanding multi-axis applications.

The servo drives weigh only 8g, making it the world’s smallest servo drives, according to the company. Denali also has dual loop support for precision, fast servo loops for smooth operation, PWN frequency up to 150 kHz for low inductance motors, high efficiency and low standby power consumption — up to 99% efficiency, and is cost-optimized for distributed-centralized multi-axis configurations.
