Linear Cylinders
Compact, High Thrust Linear Actuator
Using aluminum for the rod, these motorized cylinders produce high thrust force despite their compact and lightweight body. The unique structure suppresses vibration to achieve improved acceleration characteristics and high-speed positioning operation.
Flexible Installation
The EAC Series cylinders can be installed as follows.
Variable Cable Outlet Direction
The motor attachment direction can be changed to any of 4 directions*, allowing the cable outlet to be changed to best suit the installation location.
*3 directions for reversed motor types.
Application Example
High Speed Driving
High Response
By utilizing the high response of the stepper motor, short distances can be covered quickly. Movement follows commands without delay.
Reversed Motor Type

Reversed Motor types are provided for all linear actuators. This contributes to a shorter overall length and space savings.
Simple Maintenance for Reversed Motor Type
Maintainability has been improved by using Oriental Motor's unique belt tension adjustment mechanism and through the standardization of maintenance parts based on the AZ Series.
Thanks to Oriental Motor's unique belt tension adjustment mechanism, belt replacement is easy.
If the screw is loosened, the belt tension is adjusted to an appropriate value by the force of the spring.
Shaft Guide with Cover

There is no need to design or procure parts for the external guide. Moving parts on the cylinder main unit side are protected, improving equipment safety. This is useful for grease splash prevention in the shaft guide section and the prevention of the infiltration of foreign particles in the linear bush section.
Electromagnetic Brake
Vertical operation is possible with electromagnetic brake. The load position can be held when the power is cut off. Since the work will not fall in case of power failure or disconnection, you can safely use equipment in which the work moves vertically.
No External Sensors Required
Because the absolute motor sensor (ABZO) is built-in, there's no need for a battery to store the positioning information, or for a home sensor, or external sensors or any other external sensors.
- Cost Reduction
- Simplified Wiring
- Not Affected by Sensor Malfunctions
- Improved Return-to-Home Accuracy
High-Speed Return-to-Home
Regular Return-to-Home
With the use of limit sensors and home sensors to detect the home point at low speeds, return-to-home is time consuming.
Return-to-Home Operation of the AZ Series
Without the need to detect using limit sensors or the home sensor, the equipment can travel directly at high speed of the home position recorded by the motor sensor.

Return-to-Home Not Required (For built-in controller type)
Since the position information is known even when the power supply is turned off, operation can resume without return-to-home after an emergency stop or power outage.

Mechanical Type Absolute Encoder Motor
Advanced Technology at Affordable Prices
Oriental Motor has developed and patented a compact, low-cost, battery-free mechanical type absolute sensor. The AZ Series is available at affordable prices and can contribute to improved productivity and cost reductions.
Mechanical-Type Encoder (No Battery Required)
A mechanical sensor composed of multiple gears is employed. Positioning information is detected by recognizing the angle of the individual gears. As a result, it does not require a battery.
Multiple-Rotation Absolute System*
Absolute position detection is possible with ±900 rotations (1800 rotations) of the motor shaft from the home position.
Home Setting Method*
The home position can be easily set by pressing a switch on the drivers surface, which is saved by the Mechanical Absolute Encoder. In addition, home setting is possible with the MEXE02 data setting software or external input signal.
Home position is easy to adjust by moving the motor to a desired position manually.
*Requires AZ Series Driver
No Battery Required
No battery is required thanks to a mechanical-type sensor. Because positioning information is managed mechanically by the Mechanical Absolute Encoder, the positioning information can be preserved, even if the power turns off, or the cable between the motor and the driver is disconnected.
Reduced Maintenance
Because there is no battery that needs replacement, maintenance time and costs can be reduced.
Unlimited Driver Installation Possibilities
Because there is no need to secure space for battery replacement, there are no restrictions on the installation location of the driver, improving the flexibility and freedom of the layout design of the control box.
Safe for Overseas Shipping
Normal batteries will self-discharge, so care must be taken when the equipment requires a long shipping time, such as when being sent overseas. The Mechanical Absolute Encoder does not require a battery, so there is no limit to how long the positioning information is maintained. In addition, there is no need to worry about various safety regulations, which must be taken into consideration when shipping a battery overseas.
Position Holding Even when the Cable between the Motor and Driver is Detached
Positioning information is stored within the Mechanical Absolute Encoder.
*Because the positioning information is stored in the Mechanical Absolute Encoder, the home position must be reset if the motor is replaced.
High Reliability
High Reliability is provided by using the control method unique to Oriental Motor that combines the merits of both open loop control and closed loop control.
Continues Operation Even with Sudden Load Fluctuation and Sudden Acceleration
In normal conditions, it operates synchronously with pulse commands under open loop control, and because of its compact size and high torque generation, it has excellent acceleration performance and response. In an overload condition, it switches immediately to closed loop control to correct the position.
Alarm Signal Output in Case of Abnormality
If a continuous overload is applied, an alarm signal is output. Also, when the positioning is completed, a signal is output. This provides high reliability.
No Tuning Required
Because it is normally operated with open loop control, positioning is still possible without gain tuning even when the load fluctuates due to the use of a belt mechanism, cam or chain drive, etc.
Holding the Stop Position
During positioning, the motor stops with its own holding force without hunting. Because of this, it is ideal for applications where the low rigidity of the mechanism requires absence of vibration upon stopping.
Energy Saving
Heat generation is reduced thanks to the high efficiency motor, resulting in energy savings.
Lower Heat Generation
Heat generation by the motor has been significantly reduced through higher efficiency.
Built-in Controller (Network) Type Driver
Built-in Controller (Stored Data Type) Driver
With the built-in controller type, the operating data is set in the driver and is selected and executed from a host system. Host system connection and control are performed with ; I/O, Modbus (RTU) / RS-485 or FA network.
Equipped with an Interface that Connects to Various Master Control Systems

FLEX is the generic name for products that are used for Factory Automation (FA) network control via I/O control, Modbus (RTU) control, or a network converter.
FLEX products enable easy connection, easy control, and reduce the complexity of system configuration.
By using a network converter (sold separately), CC-link, MECHATROLINK or EtherCAT communication are possible. Operating data, parameter settings and operation commands can be input via various communication types. Its ability to accommodate the network being used results in shortened design time.
Program Simplification with Easy Sequence Function
Sequence control program simplification is possible with the built-in controller type by incorporating output signals for controlling other devices and external input signals, such as sensors.
The built-in controller type driver can set and execute independently, up-to 256 items of operating data, such as motor speed and index length. With the sequential control, it is possible to form a simple system without a master controller. This is ideal for index and return operations or aligned transportation, such as lifespan or durability tests.
- Number of positioning operation data settings (up to 256 data settings)
- Number of general-purpose input/output points (9 input points, 6 output points)
- Number of input/output points for communication (16 input points, 16 output points)

Network Gateways
The communication protocol of the master controller, Factory Automation (FA) network, is converted to Oriental Motor's own RS-485 communication protocol. Connection to Oriental Motor's network compatible products is completed with one RS-485 communication cable.
- Compatible Networks:
CC-Link, MECHATROLINK-II, MECHATROLINK-III, EtherCat
