ジイエムシーヒルストン List of Products and Services

♦ Two shaft motors are arranged on each of the XY axes, enabling high-precision positioning. ♦ There is no friction, so there is no degradation of precision due to wear. ♦ All axes, XY and Θ, are driven by shaft motors, ensuring stable precision with a low-profile design. ♦ Shaft motors can be selected and customized based on operating and load conditions.

The accuracy of the shaft motor follows that of the linear encoder used in conjunction. If the encoder has high accuracy (fine resolution), the repeat positioning accuracy will improve accordingly, and if the resolution is coarse, the repeat positioning accuracy will also become coarse.

The shaft motor is… ■ A linear (direct drive) motor. ■ Shaft type (cylindrical type). ■ Coreless motor. ■ Servo motor. It has a structure where magnets loaded on the shaft are surrounded by coils in a 360-degree manner. There is an air gap between the shaft and the coil (slider, movable part), and they do not make contact. Position recognition is done using an encoder. The higher the resolution of the encoder, the greater the positioning accuracy. When the shaft is fixed, the slider moves, and conversely, when the slider is fixed, the shaft is driven. It is supported by linear guides. Features include… ■ No cogging (no speed fluctuations) and good uniformity. ■ High repeat positioning accuracy, allowing for precise positioning. ■ High responsiveness in operation, capable of moving quickly and stopping swiftly. ■ Capable of high-speed drive while remaining quiet. ■ Maintenance-free with a long lifespan. And more. It is used in a wide range of industries, including manufacturing equipment and measurement/inspection equipment. We offer a wide lineup and customization to meet customer requests.

※Exhibiting at SEMICON Japan from December 11 to 13, 2024, at Booth #3121! The shaft motor is a linear motor that achieves high-precision drive and high-precision positioning. This XY stage features… ♦ Parallel drive for both the upper and lower axes (driven by two motors with one amplifier and one set of encoders) ♦ A hollow structure stage made possible by the parallel drive ♦ A low-profile, simple structure XY stage that eliminates waste ♦ Customizable shaft motors that meet your desired load and operating conditions.

The Shaft Motor S Series / L Series / SX Series has the following features: - No speed fluctuations - No vibrations - Capable of moving at a constant speed It can be used in devices and measurement equipment that require constant speed and dislike vibrations, such as coating devices, dispensers, image inspection devices, imaging devices, and laser devices.

The basic set for driving the shaft motor consists of the following devices… ● Shaft motor ● Controller/servo amplifier ● Linear encoder ● Linear guide

The "S Series" is a shaft motor capable of high-speed, high-efficiency, and high-precision positioning. Starting with the "S040," which is easy to replace with a ball screw mechanism due to its shape, and including the "S080," which allows multiple synchronized parallel drives with a single driver, there is a wide lineup available. You can select the appropriate thrust according to your application. 【S040 Features】 ■ High-speed operation (tact time reduction) ■ High-precision positioning (full closed-loop control) ■ Overwhelming speed stability ■ High-speed settling (high response) ■ Easy to replace with a ball screw mechanism due to its shape *For more details, please refer to the PDF materials or feel free to contact us.

We handle the shaft motor "L Series." Due to the large gap specification, there is a wide space between the movable part and the shaft, allowing for long strokes. We offer a lineup including the durable "L250" and the "L320," which can be used in harsh environments such as water, oil, contamination, and dust. 【Features】 ■ The shape makes it easy to replace ball screw mechanisms. ■ Multi-drive capability with a single shaft. ■ Multiple synchronous parallel drives possible with one driver. ■ Non-contact motor, providing excellent durability (reducing maintenance costs). ■ Usable in harsh environments such as water, oil, contamination, and dust. *For more details, please refer to the PDF materials or feel free to contact us.

The shaft motor is a unique coreless linear motor with a cylindrical (shaft) configuration of magnets. The motor is divided into a shaft section and a coil section, and by passing current through it, the coil section operates repeatedly at a very high speed and stable velocity. Since the shaft section (magnet) and the coil section are non-contact and have no friction, it excels in high speed, constant velocity, and high precision, demonstrating performance that was unimaginable with existing linear motor products. 【Features】 ■ Coreless linear motor ■ Non-contact and frictionless between the shaft section (magnet) and the coil section ■ Excellent in high speed, constant velocity, and high precision *For more details, please refer to the PDF document or feel free to contact us.

Inside the shaft, there is a structure where magnets are joined with N poles facing each other and S poles facing each other, generating strong magnetic field lines from the junction. When current flows through the coil surrounding this shaft, a magnetic field is generated, and thrust is produced according to Fleming's left-hand rule. This thrust causes the coil (slider) to move if the shaft is fixed, and if the slider is fixed, the shaft operates. Additionally, unlike conventional linear motors, this design effectively utilizes the magnetic flux of the magnets without waste in a 360-degree manner, not only generating significant thrust with high efficiency but also maintaining a constant thrust regardless of any eccentricity in the shaft, resulting in a linear motor with high rigidity.

By utilizing the characteristics of the shaft motor, it is possible to "drive simultaneously" two parallel axes without synchronizing them, as if they were synchronized. [Parallel Drive with Shaft Motor] By using a shaft motor with two axes, one set of encoders, and one driver to distribute current to the two axes, it is possible to achieve "simultaneous drive" of the two axes. *Reference* [Conventional Synchronized Drive] Two linear motors, two sets of encoders, and two drivers are required to synchronize the two axes... a labor-intensive task.

The "SX Series" is a shaft motor designed to increase thrust compared to conventional models. We offer a lineup including the "SX060," which allows for multi-drive with a single shaft, the "SX080," known for its excellent durability, and the "SX100," which is easy to replace with a ball screw mechanism due to its shape. 【SX060 Features】 ■ High-speed operation (tact time reduction) ■ High-precision positioning (full closed control) ■ Overwhelming speed stability ■ High-speed settling (high response) ■ Easy replacement with a ball screw mechanism due to its shape *For more details, please refer to the PDF document or feel free to contact us.
