Lead Screw Linear Actuator Attachment for Stepper Motors

Lead Screw Linear Actuator Attachment for Stepper Motors

The Mounting Adapter for Linear Actuators is a linear motion mechanism with a lead screw and resin nut. It saves space and reduces design time compared to a custom-built mechanism. Use these with 28 mm and 42 mm frame size 2-Phase and 5-Phase PKP Series stepper motors or AZ Series Hybrid Step-Servo motors with multi-turn absolute position control and sensorless homing.

Linear motion mechanism with a leadscrew and a wear-resistant resin nut
Easy installation without the need of coupling to an Oriental Motor stepper motor
For the 30 mm frame size, thrust and self locking force are both at max. 40 N
For the 42 mm frame size, thrust and self locking force are both at max. 100 N

Linear Actuator Attachment for Easy Stepper Motor Assembly

The Mounting Adapter for Linear Actuators is a linear actuator attachment for use with stepper motors.

This product consists of a lead screw and plastic nut and can be easily assembled without the need for a coupling. It saves space and reduces design time compared to a custom-built mechanism.

Thrust Force 100 N for 42 mm

Syringe Pump

Thrust Force of 100 N for 42 mm Frame Size Permissible Speed 180 mm/s

Compact with high thrust and high speed. This helps reduce the equipment tact time.

Thrust Force

Self-Locking Force* Max. 100 N (Frame Size: 42 mm Lead: 2 mm) Capable of Load Holding

The mechanism has a self-locking capability, making it suitable for load holding applications, such as preventing a load from dropping or moving due to its own weight.

*The phenomenon in which a screw shaft becomes immobile due to friction caused by moving the nut externally is called self-locking.

Self-Locking Force 100 N (Lead 2 mm)

Load Holding

Advantages

Reduced Heat Generation: By holding the load in the non-excitation state, heat generation is reduced through shorter excitation times
Cost Reduction: Electromagnetic brake for load holding can be reduced (for lead of 2 mm)

Compact Design Allows for Quicker Equipment Development

By using a mounting adapter for linear actuators, space is saved due to the reduced number of parts. The amount of time required for installation and accuracy adjustment can also be reduced. This allows for equipment startup in a shorter time.

Compact Design

Axial Load Can Be Applied Directly

The axial bearing mechanism enables direct support of axial loads. This is a highly reliable mounting adapter for linear actuators.

Axial Load Applied Directly

Highly Wear-Resistant Resin Nut Used

By using a highly wear-resistant plastic nut, backlash variation that increases with travel distance is reduced.

Wide Variety of Motors and Drivers to Provide More Reliable Motion

A motor equipped with additional features such as a built-in encoder, electromagnetic brake, and battery-free absolute encoder can be used in combination with a driver that provides low-vibration, low-noise operation, and FA network compatibility.
