    \u03c4DISC<\/h4>\n\n\n\n

    This is a rotary direct drive motor that is hollow. Equipped with a high-resolution encoder, the product can generate a large torque at low speed (typically 180 rpm or less) while being compact in shape. Its multi-pole structure enables smooth rotation even in an extremely low speed range. The rated torque ranges from 1.6 N\u2219m to 2000 N\u2219m. The lineup consists of more than 50 models.<\/p>\n\n\n\n

    \u03c4iD roll<\/h4>\n\n\n\n

    While being compact, this cylinder-type direct drive motor offers large torques (rated torque: 150 N\u2219m to 7500 N\u2219m). It provides high accuracy, high response, and cleanliness to general industrial machines that are driven by the conventional geared AC servo motor, such as injection molders and servo presses.<\/p>\n\n\n\n

    \u03c4Linear<\/h4>\n\n\n\n

    This is a straight line motion-type linear motor. There are two types: the core type with an iron core in the coil and the coreless type without an iron core. The coreless type without an iron core in particular can generate high thrust while being more compact and thinner than competitors’ products.<\/p>\n\n\n\n

    \u03c4Servo Compass<\/h4>\n\n\n\n

    This is a linear motor that produces an arc motion, which is best suited to positioning in a limited motion range. The maximum motion range is 360 degrees. With the motor and encoder placed in a radial direction from the center of rotation, the motor can generate a large torque, despite its low output, enabling ultra high-accuracy positioning. Since there is no drive mechanism near the center of rotation, the motor can have a large hollow, providing a significantly high level of flexibility in equipment design.<\/p>\n\n\n\n

    \u03c4Linear Stage<\/h4>\n\n\n\n

    A linear stage is a stack-type table mechanism that provides flexible motion and positioning functions when used in combination with an actuator that can freely move in each of the X (horizontal) axis, Y (horizontal) axis, \u03b8 (rotation) axis, and Z (vertical) axis. Combining this linear stage with any of the direct drive motors mentioned above makes for a lightweight, compact, highly rigid product with a simple structure that takes advantage of the benefits of the direct drive. Such a product enables positioning with submicron accuracy and increased takt time performance.<\/p>\n\n\n\n

    Stage block<\/h4>\n\n\n\n

    This cost-oriented linear stage is ideal for transport applications. By combining the stage block with a direct drive motor, it is easy to build X, XY, X\u03b8, and XY\u03b8 stages with various strokes. The lineup also includes long-stroke models best suited for use in high-speed, long-distance transport.<\/p>\n<\/div><\/div>\n\n\n\n

    Technical details<\/h3>\n\n\n\n
    \n
    What are the benefits of a direct drive motor?<\/span>
    <\/i><\/div><\/div>
    \n

    Generally, a direct drive motor has the benefits mentioned below. For information about the benefits of our products, see Features of the NIKKI direct drive motors<\/a>.<\/p>\n\n\n\n

    Major benefits of the direct drive<\/h4>\n\n\n\n
    Improvement in mechanical performance<\/h5>\n\n\n\n

    The omission of the intermediate mechanism makes it possible to increase the rigidity of the driving system and the mechanical resonance point, allowing the control characteristics of the servo motor to be reflected directly in the equipment. This substantially improves the mechanical performance, such as response performance, speed stability, and positioning accuracy, leading to higher quality and higher productivity among other things.<\/p>\n\n\n\n

    Space saving<\/h5>\n\n\n\n

    The omission of the intermediate mechanism helps make the machine more compact and provides greater design flexibility.<\/p>\n\n\n\n

    Improvement in environmental performance<\/h5>\n\n\n\n

    The omission of the intermediate mechanism reduces mechanical noise. There is no powder dust generated as the intermediate mechanism wears out, which leads to a cleaner environment. When you switch from a hydraulic drive to an electric drive, there will no longer be no oil leak or other similar problem, enhancing environmental friendliness and safety.<\/p>\n\n\n\n

    Less maintenance work<\/h5>\n\n\n\n

    There is no need to replace the intermediate mechanism due to breakage, adjustment, wear, or the end of life.<\/p>\n\n\n\n

    Energy saving<\/h5>\n\n\n\n

    Since there is no energy lost in the intermediate mechanism, the drive can be operated more efficiently, leading to energy saving.<\/p>\n\n\n\n

    \"\"<\/figure>\n<\/div><\/div>\n\n\n\n
    What is the difference in drive performance between a direct drive motor and an AC servo motor with a speed reducer?<\/span>
    <\/i><\/div><\/div>
    \n

    The general-purpose AC servo motor generates a large torque effectively using an intermediate mechanism (speed reducer, belt, chain, etc.). A direct drive motor is a motor directly connected to the load (driven body) to transmit power or motion. There is no intermediate mechanism between the motor and driven body, which makes the power transmission system more rigid and enables backlash-less, high-speed accurate driving. For details, see Basic knowledge of the direct drive motor<\/a><\/p>\n\n\n\n

    \"\"<\/figure>\n<\/div><\/div>\n\n\n\n
    What are direct drive motors used for?<\/span>
    <\/i><\/div><\/div>
    \n

    Direct drive motors are used mainly in manufacturing, processing, and transport machines for semiconductors, liquid crystal substrates, and electronic components, as well as in printers, testers, medical equipment, and molding machines. For details, see Usage examples of the direct drive motor.<\/a> Direct drive motors can be used in all types of equipment that require the performance characteristics mentioned below.<\/p>\n\n\n\n

    Higher equipment performance<\/h5>\n\n\n\n

    Higher accuracy, shorter takt time, and higher precision are achieved.<\/p>\n\n\n\n

    Improvement in the equipment’s environmental performance<\/h5>\n\n\n\n

    The equipment is quieter, more compact, and maintenance-free.

    What is the difference between a linear stage and a ball screw drive?<\/span>
    <\/i><\/div><\/div>
    \n

    A linear stage is a table mechanism equipped with a linear servo motor. Since it has no intermediate mechanism, the linear stage saves space and achieves excellent speed stability and high-accuracy positioning, compared to conventional transport mechanisms (ball screw, rack and pinion, belt, etc.). <\/p>\n<\/div><\/div>\n\n\n\n

    Major benefits of the linear stage<\/span>
    <\/i><\/div><\/div>
    \n

    Generally, a liner stage has the benefits mentioned below. For information about the benefits of our products, see Features of NIKKI linear stages.<\/p>\n\n\n\n

    Major benefits of the linear stage<\/h4>\n\n\n\n

    Improvement in mechanical performance<\/h5>\n\n\n\n

    The omission of the intermediate mechanism makes it possible to increase the rigidity of the driving system and the mechanical resonance point, allowing the control characteristics of the servo motor to be reflected directly in the equipment. This substantially improves the mechanical performance, such as response performance, speed stability, and positioning accuracy, leading to higher quality and higher productivity among other things.<\/p>\n\n\n\n

    Space saving<\/h5>\n\n\n\n

    The omission of the intermediate mechanism helps make the machine more compact and provides greater design flexibility. A linear stage with multiple heads can make the mechanism much simpler.<\/p>\n\n\n\n

    Improvement in environmental performance<\/h5>\n\n\n\n

    The omission of the intermediate mechanism reduces mechanical noise. There is no powder dust generated as the intermediate mechanism wears out, which leads to a cleaner environment. When you switch from a hydraulic drive to an electric drive, there will no longer be no oil leak or other similar problem, enhancing environmental friendliness and safety.<\/p>\n\n\n\n

    Less maintenance work<\/h5>\n\n\n\n

    There is no need to replace the intermediate mechanism due to breakage, adjustment, wear, or the end of life.<\/p>\n\n\n\n

    Long-distance drive<\/h5>\n\n\n\n

    High-speed motion over a long distance is possible because there is no deflection due to a ball screw.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n
