MA15 Series UniSlide

Motor-Driven UniSlide® MA15 Series


The smallest of the motorized UniSlide Linear Stages with a body width of 1.5 inches, slider length of 1.5 inches and a carrying capacity of 3 lbs. horizontal load. The MA15 can travel up to 10.5" with the 1.5" slider/carriage. The MA15 Series UniSlide is available in 4 lead screw pitches. Recommended step rate is 1000/steps per second. Because of it's light weight, the MA15 Series is ideal for moving small sensors or other light duty applications.

MA15 Series UniSlides are comprised of an aluminum alloy extruded dovetail base with 60 degree opposing V-type ways. An aluminum alloy carriage that runs in the dovetail ways of the base. MA15 lead screws are constrained and supported with pre-loaded Delrin® thrust bearings, which have pre-loaded ball bearings. The lead screw drive nut is a tension adjustable nut made of Delrin providing low friction, and minimal backlash.

The MA15 Series is part of 5 motorized UniSlide Series. Others are MA25, MA40, MA60, MB90. There is also a manual version - the A15 Series.

 

 
UniSlide Specifications – Motor-Driven Assemblies

Factors such as size of the motor, size of the payload, travel distance, mounting direction/plane, etc. effect the actual capability of any assembly. Please contact Velmex Application Engineers to configure a system that will meet your exact requirements.

UniSlide Configurations

The basic linear UniSlide is a 1-axis stage. UniSlides can be combined for multiple axes in a wide range of lengths and payload capacities. See Examples for images of various multi-axis UniSlides and combinations that include other Velmex stages.

UniSlide Configurations

 

Options/Accessories

An array of options and accessories is available for the MA15 Series UniSlide Assemblies

Adapter Plates

XY Plates – allow two UniSlides to be converted into an XY motion system. For more specifics and to see the adapter plates in use on a Velmex stage visit the UniSlide Adapters page.

A1500XY Adapter Plate

A1500XY Adapter Plate – To mount two MA15 Series UniSlide in XY.

XZ Plates – Allow UniSlide assemblies to be positioned vertically facing in any of four directions. For more specifics and to see the adapter plates in use on a Velmex stage visit the UniSlide Adapters page.

A1500XZ Adapter Plate

A1500XZ Adapter Plate– To mount a MA15 Series UniSlide to another MA15 Series in XZ.

XZ Brackets – allow UniSlide assemblies to be positioned vertically, facing in any of four directions and perpendicular to the X or Y plane. For more specifics and to see the brackets in use on a Velmex stage visit the UniSlide Adapters page.

XZ Adapter Brackets - A25 Series

A2501XZ Adapter Bracket – To mount a MA25 Series UniSlide to another MA25 Series (6"- 9") or to an A15 Series (6"- 9") in XZ. (The MA25 would be the base horizontal stage. The other stage would be mounted vertically.)
B2503XZ Adapter Bracket –To mount a MA25 Series UniSlide to another MA25 Series (over 9") or to a MA15 Series (over 9") in XZ. (The MA25 would be the base horizontal stage.)

B5990TXZ Rotary Adapter Plates

Rotary Table Adapter Plates –To mount Velmex Rotary Tables to UniSlide Assemblies either in horizontal or vertical positions.

 

B5990TXZ-BK Adapter Plate – To mount two B5990TS Rotary Tables at right angles to each other or to mount a B5990TS to any MA Series UniSlide.

Platform Shelves

Platform Shelf – A right angled bracket designed to be used with UniSlide® Elevating Tables. However, they also can be used with vertically mounted UniSlide Assemblies to support a payload. The shelf can be inverted depending on the motion required.

For more specifics and to see the shelf in use on a Velmex stage visit the UniSlide Adapters page.

UniSlides with two different size sliders

Slider Lengths – Varying length carriages (sliders) can be added to all models of UniSlide Assemblies. Choosing a longer slider reduces the standard travel distance. 1.5" is the standard slider on the MA15 Series. Optional lengths available for the MA15 are 2" or 3".

Left Right Screw Motion

Left-Right Screw Motion (-LR) – This configuration is very useful for applications where two objects must share a common axis of movement. This assembly incorporates two carriages driven by a single right- and left-hand threaded lead screw. When the knob is turned, the carriages simultaneously move toward or away from each other.

Independent Left-Right Slider UniSlide

Two Independent Carriages (-DS) – a variation on the left-right screw motion UniSlide is one containing two lead screws with control knobs at both ends of the assembly. Each lead screw and carriage operates independently.

Fixed Limit Switches on UniSlide

Limit Switches – Fixed end-of-travel limit switches are available as an option.

 

Outboard Adjustable Limit Switches – Mounted on the side rib of Velmex UniSlide Assemblies, these switches can be used to stop travel, provide more stops than the standard two, over-travel a stop point, change speed or be active in only one direction.

Fixed, End-of-travel Limit Switches – These push button switches are fixed on the outside rib of Velmex Unislide Assemblies. They are not adjustable. (Pictured MA15 and MA25 versions.)

See Limits for more information.

Black Anodized UniSlide

Finishes – Standard UniSlide Assemblies have a brushed aluminum finish. Optional finishes are available at an additional charge and include:

 

• Black Anodizing, additional colors also available. (pictured)
• Hard Coat Anodized and dyed black
• Electroless Nickel Plated
• Specialized coatings for specific applications such as food processing or medical applications
• Modifications for use in a vacuum environment

VRO with an UniSlide Assembly

Encoders and VRO™ Encoder Readout For a high resolution position readout an encoder and Velmex's VRO encoder readout can be mounted to most linear UniSlide assemblies. An encoder, mounted directly to the slider gives a true and accurate reading eliminating lead screw and backlash errors. (Not available on all UniSlide models.) SEE: Velmex Controls on the Encoders and the VRO Readout for additional details.

Double Shaft Motor with Control Knob

Motorized / Manual OperationIt is possible, using a double shaft motor, to produce a Velmex stage that can be manually operated or motor-driven. A shaft extension accommodates the either a Rogan or standard aluminum knob.

The motor is purchased separately. Customers can mount their own motors, if they chose.

Stepper Motor

Motors A variety of motors are available to power Velmex UniSlides, most popular of which is the DC step motor. Gear motors, servo motors and high resolution step motors in both AC and DC can run Velmex UniSlides. SEE: Velmex Controls on the Motors for additional details.

The motor is purchased separately. Customers can mount their own motors, if they chose.

UniSlide with a VXM Controller

VXM™ Controller Step motors coupled with a motor controller like the Velmex VXM are a cost effective solution for accurate speed and precise incremental positioning. SEE: Velmex Controls on the VXM Controller for additional details.

Velmex offers a multitude of options and accessories for all its products. Usually an option or an accessory will address your requirements. When it doesn't, we can make custom modifications, including:

• Additional holes or slots. (A drawing is required.)

• Intermediate plates to mount your payload

• Special or in between lengths of the dovetail base

• Lead screw shaft extensions

• Choice of drive nut materials, including brass and Vespel
