Motors offer excellent controllability and are therefore used as the drive sources of various automated equipment. In many cases a stepper motor is combined with various mechanical components such as a ball screw, belt and pulley, and rack and pinion to convert the motor rotation to a different type of motion needed to drive the equipment such as a linear actuator. Oriental Motor has various linear actuators consisting of a stepper motor assembled with the necessary mechanical components to meet the various needs of automated equipment.

Equipped with a motor offering excellent controllability, our linear actuators offer the following advantages over hydraulic and pneumatic actuators:
When automated equipment is designed, various factors must be taken into consideration including the production line layout, installation environment, ease of maintenance, configuration of electrical wiring and control system, and so on. This means many man-hours are needed to select the motor and other mechanical components and create a parts list, drawings, operating manuals and the like. Use of linear and rotary actuators can reduce this time and offers additional benefits.
The primary feature of automated equipment is its ability to implement a series of basic operations such as "transfer", "push" and "rotate." In other words, you can design automated equipment by selecting and combining linear and rotary actuators capable of performing these basic operations. Since all you need is to select an actuator, you can save the time and effort.
When building equipment in-house by assembling a motor and mechanical components (see illustration), the quality of assembly affects the traveling resistance and position accuracy, therefore ultimately adjustments will be needed to achieve the expected operating performance. On the other hand, our linear and rotary actuators are complete products guaranteed to provide the specified operating performance, so use of linear and rotary actuators reduces adjustment work and ensures uniform quality.
Oriental Motor offers various linear and rotary actuators to help you improve your design productivity.
The motor is integrated with a linear motion mechanism which makes this actuator ideal for transferring loads.
The motor is integrated with a linear motion mechanism, which makes this actuator ideal for pushing and pulling loads.
A stepper motor is integrated with a ball screw. An ideal actuator for pushing and pulling small loads or fine-tuning applications.
A rack and pinion mechanism combined with a motor to provide horizontal or vertical linear motion.
αSTEP 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
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.
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
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.
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.
