World's smallest servo drives introduced by Celera Motion

Celera Motion recently launched the Denali Series, which the company claims is the world's smallest servo drives. The compact and ultra-fast servo drives are perfect for a variety of service robots, surgical robots, industrial grippers, and lab automation applications. The drives measuring just 33 x 17.6 x 6 mm.

Denali is the latest addition to Celera Motion's line of premium-performance Ingenia servo drives. Celera Motion is a business unit of Novanta Inc.

Denali offers an enhanced hardware architecture as well as optimized power management, with a minimum standby power consumption of 1.2 W. The servo drives work in the 250-W power range and are designed for surgical robotics, end-effectors, haptic devices, small joints, and other compact robotics applications.

"Robotics is a very competitive market, evolving rapidly, and requiring best-in-class servo drive technology," said Marc Vila, Novanta's business director for Servo Drives. "Application-focused servo drives like Denali, where we have included features specifically required for the advanced robotic market segment, dramatically help engineers to accelerate their designs, be more competitive, and keep the focus on their core business."

The series features two versions:

  • The Denali XCR is a miniature, ready-to-use version, enabling quick installation and system commissioning.
  • Denali NET is an ultra-compact, high-power-density version. The pluggable design is optimal for a carrier board, with single or multi-axis integration.

Both versions are available with EtherCAT and CANopen communication protocols, specially optimized for demanding multi-axis applications. Denali supports EtherCAT with a bus latency down to one cycle. This improves the cost efficiency of embedding multiple axes into a single PCB.

The Denali line's key features include:

  • Compact and miniature; the world's smallest servo drives, weighing only 8 g;
  • Dual loop support for unparalleled precision;
  • Extremely fast servo loops for smooth operation;
  • PWM frequency up to 150 kHz for low-inductance motors;
  • High efficiency and low standby power consumption (up to 99% efficiency); and
  • Cost-optimized (single PCB) for distributed-centralized multi-axis configurations.

The Denali series offers versions that support multiple safety features for high-performance robotic applications where safety is paramount.

The Denali Series is the latest version of Ingenia's Summit Servo Drives Series. Others include the Capitan Series and the Everest S Series.
