AlphaStep

Linear Actuators - Motorized Linear Cylinders


EAC Closed Loop AZ Series Absolute Encoder Motorized Linear Cylinders / Linear Actuators

EAC Linear Cylinders

The AlphaStep EAC Series motorized linear actuators featuring AZ Series with absolute encoder stepper motor and driver are quick and responsive and incorporate a ball screw design, offering high performance from low speed to high speed or with light loads or heavy loads, regardless of demanding operating conditions. Available in a straight type or reversed motor type and with a shaft guide and cover version also available, saves design time and parts. All EAC Series are available with an electromechanical brake ideal for vertical operations. Available with Pulse Input or Built-in Controller (Network) type driver.

  • Equipped with battery-free absolute encoder
  • Positioning information can be known without a sensor
  • High reliability using closed loop control
  • Reduced motor heat and reduced energy consumption through high efficiency design

αSTEP Hybrid Control System

AlphaStep products are stepper motor based hybrid motors with a unique hybrid control system combining the benefits of "open loop control" and "closed loop control".

The position of the motor is always monitored, and then the driver automatically switches between 2 types of control depending on the situation.

Normally Operates in Open Loop Control for the Same Ease of Use as a Stepper Motor

Open Loop Control

High Response

By utilizing the high responsiveness of the stepper motor, moving a short distance for a short time is possible. The motors can execute commands without lag.

High Response

Holding the Stop Position without Hunting

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.

Tuning-Free

Because it is normally operated with open loop control, positioning is still possible without gain adjustment even when the load fluctuates due to the use of a belt mechanism, cam or chain drive, etc.

Switches to Closed Loop Control during Overload for More Reliable Operation like a Servo Motor

Closed Loop Control

Continues Operation Even with Sudden Load Fluctuation and Sudden Acceleration

It operates synchronously with commands using open loop control during normal conditions. In an overload condition, it switches immediately to closed loop control to correct the position.

Closed Loop Control

Alarm Signal Output in Case of Abnormality

If an overload is applied continuously, an alarm signal is output. When the positioning is complete, and END signal is output. This ensures the same level of reliability as a servo motor.
