Do you trust that new industrial automation technology consistently improves operational efficiency?
Nanotec has introduced the latest generation of its PD2 smart servos, which consolidate a NEMA 17 motor, controller, drive, and absolute encoder into a single compact device. These units are available in both stepper and brushless DC (BLDC) motor versions.
Why it matters
By integrating the controller and drive directly into the motor housing, the PD2 series simplifies robotic architecture and reduces the footprint required for precision motion control systems. The design enables complex automation tasks to be handled within a smaller physical envelope.
The PD2 series delivers up to 75% higher rated torque and power compared to its predecessors. It features an integrated absolute encoder—a sensor that tracks the motor shaft position without needing a reference run—and supports industry-standard communication protocols.
The players
Nanotec
A developer of motor and controller technology focused on compact, integrated motion control systems for robotics and industrial automation.
The details
The PD2 units function by housing the motor, controller, drive, and encoder in one integrated block to minimize wiring and space requirements. The system employs field-oriented control—a method for controlling AC motors to improve efficiency and precision—and digital I/Os with push-pull functionality for flexible signal handling. Users can utilize the NanoJ programming environment to run control logic directly on the hardware for standalone operation without a centralized controller.
Timeline
Nanotec introduced the new PD2 smart servo series in September 2026.
The Tech Race
The PD2 series follows the broader industry trend of integrating motor control logic into the physical motor frame to minimize footprint and latency in robotic systems. This approach challenges existing decentralized architectures by moving intelligence closer to the point of mechanical action.
System integrators can now utilize these units to simplify hardware stacks in precision machines, though specific commercial pricing remains unannounced. The servos support standard communication protocols including CANopen and EtherCAT for easy implementation into existing industrial workflows.
The takeaway
The PD2 series represents a significant shift toward all-in-one motor components that favor compact design without sacrificing torque performance. Engineers should watch for technical documentation updates from Nanotec regarding specific communication latency benchmarks.
