The Rack and Pinion System can easily convert the motor's rotation to linear motion. The linear motion mechanism has a compact design but it can transport large loads due to its high-strength fabrication.

A variety of transportable mass and stroke are available to match your equipment.

Reduces Startup Time

The rack-and-pinion system reduces the parts conventionally used and greatly decreases the number of work hours for design and labor.

Space Saving

The screw holes at both ends of the rack can be fixed to let the body travel. Effective for equipment whose size makes it impossible to ensure motor space.

The drive motor is equipped with the AZ Series hybrid control system. By combining with the MEXE02* support software, the linear motion can be easily set in millimeter increments, which allows for various linear motion applications.

The Rack and Pinion Systems have many applications and they are easy to use.

No Home Sensor Required

Oriental Motor has developed and patented a compact, low-cost, battery-free mechanical type absolute sensor. The αSTEP AZ Series is available at affordable prices and can contribute to improved productivity and cost reductions.

Because it is an absolute system, no home sensor is required.

High-Speed Return-to-Home Operation

Because return-to-home is possible without using a home sensor, return-to-home can be performed at high speed without taking the specifications for sensor sensitivity into account, allowing for a shortened machine cycle.

Reduced Cost

Sensor and wiring costs can be reduced, allowing for lower system costs.

Simple Wiring

Wiring is simplified, and the degree of freedom for equipment design is increased.

Not Affected by Sensor Malfunctions

No need to worry about sensor malfunctions, sensor damage or sensor disconnection.

Improved Return-to-Home Accuracy

Home position accuracy is increased because the return-to-home action is performed regardless of any variations in home sensor sensitivity.

Easy Home Position Setting

The home position can be easily set by pressing a switch on the front of the driver, which is saved by the absolute sensor. In addition, home setting is possible with the MEXE02 support software or by using an external input signal.

*Requires AZ Series Driver

Return-to-Home Not Required (Built-in Controller Type Driver)

If the power shuts down during a positioning operation, the positioning information is retained. Furthermore, for built-in controller types, positioning operations can restart without a return-to-home when recovering from an emergency stop or a blackout.

Battery-Free

No battery is required because it is a mechanical-type sensor. Because positioning information is managed mechanically by the absolute sensor, the positioning information can be preserved, even if the power turns off, or if the cable between the motor and the driver are disconnected.

Reduced Maintenance

Because there's no battery that needs replacing, 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

With normal batteries that self-discharge, care must be taken when the equipment requires a long shipping time, such as when being sent overseas. The absolute sensor does not require a battery, so there is no limit to how long the positioning information is maintained. In addition, there's 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 absolute sensor.

These products have built-in power-off activated electromagnetic brakes. When power is accidentally cut off due to a blackout or other unexpected events, the electromagnetic brake holds the load in position to prevent it from dropping or moving. Also, when the motor is at standstill, it can be held by the electromagnetic brake. It is possible to suppress the heat generated from the motor by turning off the motor current.
