As industrial automation becomes more intelligent and application-specific, machine builders and system integrators are demanding smarter motion control systems that offer greater flexibility, enhanced precision and easier integration. Whether the goal is ultra-precise positioning for laboratory instrumentation or high-torque operation to support conveyor systems, selecting the right motor technology is crucial.
Global expert, Oriental Motor addresses these needs with two advanced motion control solutions: the AZ Series and the AZX Series. While both systems incorporate the company’s innovative battery-free mechanical absolute encoder technology, they are each designed to solve very different automation challenges. Together, they offer a complete and highly adaptable motion ecosystem, suitable for a wide range of industrial sectors.
Absolute precision without the batteries
Both the AZ and AZX Series are built around Oriental Motor’s proprietary mechanical multi-turn absolute encoder. Unlike conventional absolute encoders that require battery backup or external sensors to store positional data, this mechanical system retains position information across 1800 revolutions – even when power is lost or the equipment is moved.
This innovation eliminates the need for homing sequences during power-up, reducing machine downtime and simplifying system architecture. The absence of batteries also makes both product lines ideal for sealed or maintenance-sensitive environments as there is no degradation of performance over time, or requirement for regular replacement.
Whether used in stepper or servo systems, the encoder technology ensures dependable and continuous position tracking, streamlining design and improving system resilience.
AZ Series: Compact closed-loop control for precision tasks
The AZ Series is Oriental Motor’s flagship closed-loop stepper motor platform, designed for compact and medium-duty positioning applications. It provides the ease-of-use of a stepper motor system, but with the added stability of closed-loop feedback. This ensures the motor won’t lose steps under varying loads and can automatically adjust torque output for greater energy efficiency and reduced heat generation.
Available in multiple frame sizes ranging from 20 mm to 90 mm, the AZ Series is exceptionally versatile. It supports various gear configurations, including planetary, harmonic and parallel shaft types, along with hollow shaft flat models for space-saving applications. Optional electromagnetic brakes enable vertical axis control or emergency hold during power loss.
The AZ Series is particularly well-suited to systems requiring accurate, repeatable movement in a small footprint. This includes applications in medical diagnostics, laboratory automation, small-scale pick-and-place machines, and electronic assembly systems. The motors can be integrated with network-capable drivers that support protocols such as EtherCAT, EtherNet/IP, PROFINET and Modbus, enabling them to communicate seamlessly with modern PLCs and industrial networks.
With its intuitive MEXE02 support software, users can program up to 256 motion profiles and complex control sequences without additional logic hardware. Features like sensor-less homing and built-in Safe Torque Off (STO) enhance safety and simplify machine design.
AZX Series: High-performance servo motors for demanding automation
Where higher torque, greater speed, or long-distance travel are required, the AZX Series steps in as a high-performance servo motor system. Building on the same mechanical absolute encoder foundation, the AZX Series delivers rated output options of 400 W and 600 W, with speeds up to 5500 revolutions per minute. This makes it an excellent choice for applications involving heavier loads, rapid acceleration or extended movement distances.
Like its stepper counterpart, the AZX Series is supported by network-compatible drivers, allowing for easy integration into modern control architectures. With advanced motion sequencing capabilities – including timer-based events, multi-speed loops and condition-based branching – the AZX Series enables complex motion profiles without heavy reliance on external PLC logic.
When paired with Oriental Motor’s PS-type gearheads, the AZX motors are capable of delivering significant torque even at low speeds. This is particularly beneficial in automation systems that involve linear actuators, gantry robots or vertical lifting stages. Applications in automotive assembly, packaging and logistics also benefit from the AZX Series’ speed, torque and feedback-driven control.
Housed in frame sizes from 60 mm to 120 mm and rated to IP65 for environmental protection (excluding connectors), the AZX Series is engineered to perform in both harsh and demanding industrial settings.
System integration and cross-series compatibility
One of the standout advantages of Oriental Motor’s AZ and AZX Series is their shared control philosophy and software environment. These features allow engineers to combine both product lines within the same machine or production system without complex configuration overhead. A high-speed, high-torque AZX motor can be used on a Z-axis or conveyor section, while compact AZ motors drive precise rotary or XY table movements.
With matching drivers and a common interface, multi-axis motion systems become easier to program, debug and expand. Cable lengths of up to 20 meters provide layout flexibility, while Safe Torque Off (STO) functionality across both series ensures compliance with machine safety regulations.
This scalable, modular approach enables OEMs and system integrators to develop automation systems that are not only efficient and cost-effective but also adaptable to evolving performance requirements.
Choosing the right motor for the job
In essence, the choice between AZ and AZX comes down to power and scale. The AZ Series is ideal for lighter-duty systems where precision and compact size are key, while the AZX Series is designed for more dynamic automation tasks requiring higher torque, extended travel, or faster speeds.
Both series deliver unmatched reliability and intelligence thanks to their mechanical absolute encoder and integrated control capabilities. Together, they give system designers the flexibility to build sophisticated machines without sacrificing maintainability or future scalability.
