Features | Electric Cylinder EAC Series
Features of the Cylinder Section
High Speed Driving With Light Load or Heavy Load is Possible
For the EACM6 Type


The Shortest Positioning Time Can be Easily Calculated
For applicable products of Oriental Motor's electric actuators, a support tool is available to calculate the reference positioning time according to the "model" and "operation conditions."
Stable Movement With Little Speed Fluctuation Even at Low Speeds
The microstep drive of the closed loop stepper motor allows the resolution to be increased without any mechanical elements such as a speed reduction mechanism. As a result, even at low speed (1.25 mm/s), speed fluctuation remains low with constant speed.

Compact and High Thrust Cylinder
Using aluminum for the rod, these electric cylinders generate high thrust despite their compact and lightweight body.
The vibration suppression structure improves acceleration characteristics and enables high-speed positioning operation.

Wide Range of Cylinder Variations
Product Line
The EAC Series comes in a reversed motor type as well as a straight type. Three types of cylinders are also available: Without shaft guide, with shaft guide, and with shaft guide cover.

Contributes to Space Saving (Reversed motor type)
Reversed Motor Type
Thanks to the belt mechanism, this type features a reversed motor installation direction.

Reversed motor types are available for all models. This helps shorten the overall length and saves space.

Easy Belt Replacement (Reversed motor type)
Oriental Motor's unique belt tension adjustment mechanism (patented) allows for easy belt replacement.

Direct Mounting of Load (With shaft guide/shaft guide cover)
With Shaft Guide/Shaft Guide Cover
This type has a shaft guide and cover installed, which allows for the load to be transported while attached directly to the body of this product.
Straight types and reversed motor types are available.


Advantages of Equipping With AZ Series
Battery-Free Absolute Encoder Equipped
It is equipped with a small battery-free mechanical absolute encoder (ABZO sensor). This can help improve productivity and reduce costs.

- Mechanical-Type Sensor
Retains positioning information even when power is not supplied - Multi-Rotation Absolute Encoder
Absolute position detection is possible with ±900 (1,800) revolutions of the motor shaft from the home position
No External Sensors Required
As it is an absolute system, home sensors or limit sensors are not required.
Advantages
- Improved High-Speed Return-to-Home + Return-to-Home Accuracy
- Reduced Cost
- Simple Wiring
- Not Affected by External Sensor Malfunction
Battery-Free
Mechanical sensors do not require batteries.
Positioning information is managed mechanically by the ABZO Sensor.
Advantages
- No need to replace batteries
- Unlimited Driver Installation Possibilities
- Safe for Overseas Shipping
Simplifying the Main Program via Sequence Function
The AZ Series come equipped with a wide variety of sequence functions such as timer settings for linked operation and during operations, conditional branching, and loop operation. (excluding some models)
It can be set up using the support software MEXE02, which simplifies the sequence program of the host system.

- Positioning Operation Data Setting Value (max. 256)
- General-Purpose I/O Signal Counts (Input 10, Output 6)
- Communication I/O Signal Counts (Input 16, Output 16)
Data Collection of Motor Operation Status and Functions Useful for Preventive and Predictive Maintenance
This software is equipped with various monitoring functions for checking the operating status of the motor.
By using different types of equipment for different situations, it is possible to shorten the start-up and adjustment time of the equipment, as well as to utilize it for maintenance and servicing.
Monitoring Function to Visualize the Motor Operating Status and Help Collect Data
The ABZO sensor bulit in the AZ Series allows you to monitor the motor's operating status numerically.
[Monitoring With MEXE02 Support Software]

In addition, the built-in controller type can realize data collection at a host master via industrial network.
Information Functions Useful for Preventive and Predictive Maintenance
By setting arbitrary numerical values for the monitored information items, external signals can be output when the values are reached.
Importing this information into the host controller helps in early detection of problems and adjustment of product maintenance timing.
Examples of Information Functions
-
TRIP Information
You can set the number of rotations you want to output in advance, and output when that number is reached. (Motor operation will continue)
-
Temperature Information
You can set the desired output temperature in advance, and the driver will output when it reaches that temperature. (Motor operation will continue)
Standardized Wiring, Control, and Maintenance Parts
Various actuator products equipped with the αSTEP AZ Series are available.
They each have the same motor and driver, which allows for standardized wiring, control, and maintenance parts.
Wiring Standardization
The wiring for motor cables, I/O signals, and power supply is the same.
Control Standardization
These products can be operated via the same method, since the control method is the same. For the network control, the remote I/O and the command code are also the same. It saves you the trouble of creating a program.
Unification of Maintenance Parts
Maintenance parts can be minimized, since the motor, driver, and cable are common to all. Management costs (parts cost, management space) can be reduced.
