Linear Spring Series
The new linear springs series offers a selection of spring loads that react along a straight line, as opposed to a conventional spring that fits in a circular cavity. This means a linear spring may be located in an axial direction but it provides a radial force.

Smalley Linear Springs are a continuous wave-formed wire length produced from spring-tempered materials. Linear Springs act as a load-bearing device having approximately the same load/deflection characteristics as a wave spring. Axial pressure is obtained by laying the linear spring flat in a straight line.

Linear Springs are now available as a standard part from Smalley. More than 200 standard sizes are available from stock in both carbon and stainless steel.

High Performance Disc-Magnet Motor
An integrated solution, the P532 series disc-magnet step motor with encoder is shown to deliver a power rate and acceleration that outperforms standard brushless DC motors in a wide range of applications where closed loop performance is needed. The P532 series motor has a diameter of 52mm, length up to 55mm, and rated torque of 0.2Nm (boosted up to 0.5Nm). This allows the P532 to deliver dynamic performance with acceleration up to 400K rad/sec2. Such performance is suited for applications where rapid changes in rotation are required (±3,000rpm in a few ms).

Highlights

• Precise – Well suited for micro-stepping
• Fast – Disc Magnet enables fast acceleration and high top speed of any step motor while maintaining accurate positioning
• Unique – Low detent torque and highly customizable
• Adaptable – Higher steps per revolution than similar diameter steppers

Small Profile Optical Encoder
The RSF MS 14 encoder system fulfills the need for a small package, high-resolution encoder that has a repeatable optical reference mark, along with an easy visual display of signal quality. Available in North America through parent company Heidenhain Corp., this frictionless kit-style encoder is perfect for motion feedback applications where high resolution and small mechanical size are necessities.

The multi-colored signal status LED on the MS 14 scanning unit makes the mounting quality visible at a glance during installation. The status display also makes it possible to quickly and easily check the signal quality right at the scanning unit during normal operation.

The optical reference mark is bi-directional and is not affected by magnetic fields of linear motors. The scanning unit dimensions allow it to be installed as a direct mechanical replacement to other encoder brands by implementing the scanning unit and MS 14 scale tape.

The North American contact for RSF products is Kevin Kaufenberg, who can be reached at 847.490.0387 or kkaufenberg@heidenhain.com.

RSF MS 14 QUICKLY

• Available with accuracy grades of ±5µm and ±15µm, depending on scale tape mounting method
• Provides a grating period of 40µm for analog systems (for digital systems, signal periods from 2µm down to 100nm are available)
