Overview of Rack-and-Pinion System

The rack-and-pinion system can easily convert the rotation of the motor into linear motion.
Although the linear motion mechanism part is compact in design, it can transport a large load due to its high strength processing.

Overview of Rack-and-Pinion System

Contributing to Design Efficiency

Reduces Startup Time From Design

In comparison to building a rack-and-pinion mechanism yourself, the number of parts used and the man-hours required for design and assembly can be reduced.

Component Comparison

Space Saving

The motor can run by itself by fixing both ends of the rack. Effective for installation where motor space is difficult to secure.

Space saving

Reduced Labor for Assembly and Maintenance

Can be Easily Combined With a Parallel Shaft Gearhead

Installation and maintenance of the motor can be easily performed.

Can be easily combined with a parallel shaft gearhead

The Rack Can be Mounted Both Horizontally and Vertically

The ability to freely choose the mounting direction adds to improved ease of design and cost reductions through the sharing of parts.

The rack can be mounted both horizontally and vertically


The rack-and-pinion system, which can be applied to a variety of applications, is a user-friendly product that can be selected as if it were a component.

Examples of In-House Production of Equipment Load Elevating and Lowering Equipment

Real examples from the Oriental Motor production facilities of load elevating and lowering equipment used to explain points for adoption of products.
Oriental Motor's extensive product lineup and wide range of services contribute to overall reduced costs, by shortening startup times, and equipment design with specifications to meet your needs.

Labor-Saving Ideas

At Japan's Manufacturing sites, labor shortages due to a decline in the working population associated with the decreasing birthrate and aging population is becoming an issue. Amidst this, there is an urgent need for labor-saving that reduces the burden of "heavy lifting work" and "repetitive work such as sorting." Rack-and-pinion system that transports high loads contributing to labor-saving in manufacturing operations.

Reducing the Burden on the Body
Loading and unloading of buckets, which places a burden on the body. Automatic lifting equipment using a rack-and-pinion system can reduce the burden on the operator.

Advantages of Combination 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.

ABZO sensor
  • 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.


  • Improved High-Speed Return-to-Home + Return-to-Home Accuracy
  • Reduced Cost
  • Simple Wiring
  • Not Affected by External Sensor Malfunction


Mechanical sensors do not require batteries.
Positioning information is managed mechanically by the ABZO Sensor.


  • 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)

Return-to-Home Not Required (Built-in controller type)

Even if the power shuts down during a positioning operation, the position information is retained. With the built-in controller type, the positioning operation can be restarted without performing return-to-home, after an emergency stop on the production line or a blackout.

Return-to-Home Not Required

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.

In addition, the built-in controller type can realize data collection at a host master via industrial network.

Types of network converters and the industrial networks they support

Information Functions Useful for Preventive and Predictive Maintenance

By setting arbitrary numerical values for the monitor items of each source of information, 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)

TRIP Information
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.
Each of them has the same motor and driver, for standardized wiring, control, and maintenance parts.

Wiring Standardization

The wiring for motor cables, input/output signals, and the 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.
