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.

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.

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.

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.

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)
