The Green Drive currently is available in two sizes, the G16x series and G25x series. The G16x series features a shaft (magnets) with a 16mm diameter and the G25x a 25mm shaft diameter. The G16x series is 66mm wide and high, while the G25x series is 88mm wide and high. Each has varying lengths depending on the required effective stroke.

Nippon Pulse will be highlighting the Green Drive at the ATX West tradeshow in Anaheim, CA in mid-February. Those interested in the Green Drive can visit booth #4348 to learn more about the actuator.

Nippon Pulse’s new SLP Linear Stage ideal for industrial applications

Nippon Pulse (www.nipponpulse.com) has announced that its high precision SLP Acculine single-axis linear stage series comes with the ability to simplify the transition from conventional linear motion systems including pneumatic actuators, belt and chain drives and ball screws. The new SLP stage has integrated the company’s successful Linear Shaft Motor into its all-inclusive stage to provide useful solutions for various industrial applications.

The SLP linear stage is also fitted with shaft support in the housing, while simplifying transition from traditional ball screw systems. Meanwhile, the addition of Nippon Pulse’s Linear Shaft Motor effectively makes the SLP stage a low-profile, high-precision product.

The company’s Linear Shaft Motor features three fundamental concepts. First, it is simple as it consists of only a forcer and a magnetic shaft. Second, the shaft motor is high-precision, providing sub-micron resolution. This is attributed to several factors, such as less heat generation, stiffness that is up to 100 times more than other linear motors, no Eddy currents and no cogging issues. Finally, the non-contact shaft motor also features a non-critical air-gap, eliminating variation in force over the device’s stroke.

Offering the highest force-to-volume ratio, the all-new SLP stage is an ideal solution for those working in space-restricted environments. Unlike other linear stage currently offered on the market, the single-axis linear stage series offers the smallest dead zone.

Linear Shaft Motor caters to ultra high-precision market

Nippon Pulse (www.nipponpulse.com) has introduced the first linear motor that is constructed and designed with the intention of catering the demands of ultra-high precision market. The Linear Shaft Motor’s distinct features are more energy efficient compared to similar linear motors of its kind.

Achieving motion profiles that similar linear motors fail to achieve, the Nippon Pulse Linear Shaft Motor is specifically designed to provide stiffness that is 100 times greater than other ironless linear motors, maximize the use of magnetic flux, minimize the heat generated and reduce the heat’s impact on the work point. Its remarkable features eliminate cogging issues and the problem of Eddy currents, enabling it to achieve sub-micron motion profiles.

Its cylindrical design allows users to utilize 100 percent of the magnetic flux, which can be used at a maximum efficiency. All magnetic flux cuts the coils at an angle of 90°.

Despite of the Linear Shaft Motor’s completely ironless construction and because of its cylindrical feature, it delivers stiffness that is 100 times greater compared to other linear motors in its class.

Aside from not producing Eddy currents and the absence of cogging issues, it also produces less heat than other linear motors in the market. Thus, the motor achieves accurate and precise motion profiles as it does not deposit heat into the work point. The lack of inherent airflow restrictions enables the motor to lessen heat production.

Nippon Pulse introduces L427 Series Linear Shaft Servomotor

RADFORD, VA — Nippon Pulse has introduced the L427 series, a linear shaft servomotor that features a 5mm air gap between the forcer and magnetic shaft. In the Linear Shaft Motor (LSM) family, the L427 series is a low-maintenance linear motion solution that has applications in a wide industry range.

With a 5mm air gap between the motors forcer and shaft, users have more flexibility when machining their device to level. It is also a good motion solution when a user does not have the ability or resources to do an accurate alignment of the forcer and the shaft.

The L427 series is an optimal solution in environments where there is the potential for matter to stick to and build up on the shaft. When there is the potential for debris to build up on the shaft, the 5mm air gap will prevent the motor from jamming and will also increase the time required between cleanings.

The L427 features a usable stroke length between 100 and 4,600 millimeters and has a constant force of 110N. The motor’s peak force is 450N, while its force constant is 31(Kf) N/Amps. Other features of the product include a 42.7 mm shaft diameter, a 3.6A continuous current, a 14A peak current, a 10 V/m/s back EMF, and a 3kg forcer weight.

Nippon Pulse’s Linear Shaft Motor has three basic concepts. It is simple, consisting of only a magnetic shaft and a forcer. The motor is also high precision, taking advantage of its ironless make-up to offer zero cogging, while giving complete stiffness. Being non-contact, the shaft motor has a non-critical air-gap that eliminates variation in force over the entire stroke of the device.

SCR Nanopositioning Stage from Nippon Pulse America

RADFORD, VA – The Nippon Pulse America, Inc. (NPA) SCR100 stage is an ultra high precision, compact single-axis stage that integrates a slide guide, encoder, and Linear Shaft Motor. The SCR100 stage offers a wide range of advantages for ultra high performance and accuracy applications. Through complex motion profiles, the SCR series produces extremely accurate results and because of its built-in shaft support yields no stability.

The SCR100 stage is a moving magnet design, which locates all cables and connectors in the stationary base. The resulting absence of any moving cable is clean and compact and eliminates motion errors due to cable forces. The precision ground cross roller way provides high stiffness and smooth motion. Together they are capable of supporting higher torque levels due to offset loads with travels from 50mm to 300mm. The non-contact Linear Shaft Motor and optical linear encoders are self-contained inside the stage, making it a low-profile compact solution. The built-in non-contact optical linear encoder is available with resolutions from 1 micron to 10 nanometers with digital output. The sub-micron resolution results in a high accuracy stage, which is laser tested for optimum performance.

The Linear Shaft Motor is a coreless direct drive linear motor that, because there is no cogging, has a higher resolution, speed, and continuous force than standard stepper motors and piezo servomotors. The Nippon Pulse Linear Shaft Motor has gained a reputation of servicing the very demanding, ultra high precision motion control applications in a number of markets. Those markets include Metrology, Spectroscopy, Digital pathology, Microscopy, Disk drive, Semiconductor fabrication, Biomedical, Pharmaceutical, Life Sciences, Cell Imaging, Particle Analysis, Medical Device, Stent fabrication, National Laboratories, Photonics/Telecom, Aerospace and Defense and Genomics.

The SCR100 stage has the added benefit that any standard digital servo driver can drive the SCR100 stage. Any two SCR stages will bolt directly together to form a very stiff, compact X-Y stage. Two SCR stages can be supplied as an X-Y stage to insure true orthogonal orientation.
