EMB-LM1
$895

The EMB-LM1 is a linear slide with an integrated optical linear incremental encoder. With a low friction ball slide, a high resolution linear encoder, and dovetails that easily interface with other EMB modules, the EMB-LM1 is ideal for plants that have translational components, including spring-mass-damper, lever mechanisms, rack and pinion, and belt driven linear slides.

The encoder measures relative displacement, and it uses standard industrial encoder signals (Ground, 5V, A, B, Index), making it easy to connect to microcontrollers as an Arduino or STM32 board, and industrial DAQs such as hardware from National Instruments. The EMB-LM1 is plug-and-play with our DAQs, using one of the encoder inputs.

The standard lines per inch (LPI) is 2000, yielding 8000 counts per inch in 4X reading. We can supply other LPI specs if your application requires, ranging from 120 LPI to 2000 LPI.

The encoder has an index signal at the center of travel.

Key features:

  • Travel: 100 mm

  • Rated Voltage: 5V

  • Incremental Encoder

  • Standard LPI: 2000 (other options available)

  • Ball slide with extremely low friction

  • M4x0.7 tapped holes on both sides and rear side of the module

  • EMB dovetail on top and bottom of the module

  • 2 end plates and fasteners included

  • Connector: M12-5 Pin

  • Anodized aluminum body

The EMB-LM2 is a linear slide module. It has the same bearing and dovetails as the EMB-LM1, but it does not have the integrated encoder. This module is recommended for applications that do not need direct displacement measurement, for example, spring-mass-damper experiments with accelerometer sensors feedback (instead of encoder). 

Key features:

  • Travel: 100 mm

  • Ball slide with extremely low friction

  • M4x0.7 tapped holes on both sides and rear side of the module

  • EMB dovetail on top and bottom of the module

  • 2 end plates and fasteners included

  • Anodized aluminum body

  • Bearing made in the USA

Very often we find rack and pinion plants in textbooks related to machine design, vibrations, dynamic systems and controls. They are a fantastic way to convert rotary motion into linear motion and are used extensively in industry.

The rack attachment mounts to the rear of the EMB-LM1/EMB-LM2 by M4x0.7 fasteners, slots allow for height adjustment with a pinion gear. Pinion gear included.

Key features:

  • Rack Module: 1.0

  • Length: 120 mm

  • Includes pinion gear

  • Anodized aluminum frame

  • Rack made in Japan

EMB-RACK ATTACHMENT
$225

Similarly to the rack and pinion, a belt driven linear plant converts rotary motion into linear motion.

Popular uses for belt driven linear motion systems include 3D printers, inkjet printers, and pick and place machines.

The belt attachment mounts to the rear of the EMB-LM1/EMB-LM2 by M4x0.7 fasteners, slots allow for height adjustment with the pulleys. An open belt or closed belt can be clamped. 1 meter of open belt included.

Key features:

  • Belt Pitch: MXL

The cam attachment mounts to the rear of the EMB-LM1/EMB-LM2 by M4x0.7 fasteners. With this attachment, students can explore plants with radial cams with a roller follower. The cams can be created using rapid prototyping manufacturing (3D printing or laser cutting, for example), and mounted to a rotary EMB module using a shaft collar (EMB-Flange Shaft Collar or EMB-Flange Shaft Collar MXL). 

If the EMB-LM1 linear slide with integrated encoder is coupled with the EMB-SM1 rotary encoder module via a cam, the students can gather rotary data and linear data, for analysis of SVAJ plot comparison.

The inverted pendulum plant is a classic example in Dynamic Systems and Controls textbooks. The EMB-Pendulum attachment lets the user create self-erecting, inverted, and non-inverted pendulum plants.

It mounts to the top dovetail of the EMB-LM1/EMB-LM2. The pendulum arm can be attached to the EMB-SM1 or EMB-SM2 modules, giving the flexibility for the user to choose an encoder or potentiometer as sensor. The dynamics of the pendulum can be adjustable, by changing the position of the mass (can be removed or placed anywhere along the length of the rod).

Swing up controllers, balance controllers, pendulum dynamics modeling, and study of gantry controllers are among the application areas for this attachment. The base is driven via the rack and pinion or belt attachments, for example. Sensor not included with this attachment.
