Achieving Accuracy with Direct Drive Rotary Stages

Achieving Accuracy with Direct Drive Rotary StagesDoes your application require an unusual level of precision? Does your current Direct Drive Rotary Stage meet your current torque requirements? If your answers to these questions was “no,” Prime Drives can design and manufacture Direct Drive Rotary Stages to meet your specific positioning needs.

Direct drive rotary stages can be designed with apertures of nearly any diameter and load capacity. Your application will determine the aperture size and load requirements.

Possible applications might include rotary testing, optical calibration, inertial navigation, electro-optic sensors (single or multi-axis), or antennas. Many fields require precise angular positioning including various electronic assemblies, medical, pharmaceutical, robotics, fiber optics, research institutions, microelectronics, photonics and defense and security.

How does a direct drive rotary stage help with accuracy?

  • Reduce or eliminate backlash
  • Better positioning accuracy
  • Increased speeds
  • Maximize performance related to tilt error
  • Reduce rotating friction
  • Eliminate wear problems connected with belt drives, worm-drive and gear-drive rotary stages
  • Reduced travel
  • Increased repeatability

An added benefit of this type of rotary stage is that it lasts longer and requires less maintenance than other rotary stage types. If space limitations are a factor, Prime Drives is able to design a Direct Drive Rotary Stage to fit within those constraints with a low profile, high precision design. with heights as small as 40 mm.

Aperture size needs may vary depending upon your application. Some factors to consider are the number of wires or vacuum lines routing through the aperture. We can design Direct Drive Rotary Stages with aperture sizes ranging from 10 to 300 mm. For more specification details refer to our product brochure or call our office at 775-333-5984.

Depending upon your specific requirements, often dictated by your industry, our team of experts can design the best possible solution for your company and your application. Whether your Direct Drive Rotary Stage needs are simple or very complex, our engineers will work closely with you to design equipment that will meet those needs.

Pancake Servo Motors Provide Long Life in Low-Profile Areas

Pancake Servo Motors Provide Long Life in Low-Profile Areas
Pancake Servo Motors are used in speed-controlled or position-controlled feedback systems to control valves within the system. They have a very low profile to fit into spaces less than 1 inch and offer high torque when it is needed for small spaces. If your application requires a long life in a low-profile area, we can provide you a solution. We can design and manufacture a Pancake Servo Motor to fit your needs.

One of the main benefits of Pancake Servo Motors is the fact they have a low-profile and can be placed into small areas. We can design and manufacture Pancake Servo Motors as small as 40 mm in total height with diameter around 80 to 300 mm, not including the shaft. Because of the small size, these Pancake Servo Motors are perfect for use inside robotics, optics and pumps.

Another benefit of the Pancake Servo Motor is that they are brushless which means they do not have mechanical components that will wear out. If there are no mechanical components to wear out, you can feel secure in placing these motors inside hard-to-get-to areas and expect them to last for a long time. If thin section or crossed roller bearings are included in the Pancake Servo Motor, it will increase the life expectancy of the motor. Despite their size, Pancake Servo Motors can provide up to 3,000 RPM.

To help you determine if you have the right Pancake Servo Motor for your application, ask yourself these questions:

  • Does my application require a specific amount of torque?
  • Does it require a detent or holding torque?
  • Does the application require a duty cycle of a particular length?
  • Is one step angle desired above another?
  • Does is the required RPM or step rate?
  • Are bipolar coils preferred over unipolar coils?
  • What coil voltage is needed?
  • What size restrictions are there for the application?
  • Do I know the anticipated life requirement for the motor?
  • What is the operating temperature for the Pancake Servo Motor?
  • Will the temperatures remain constant or will they fluctuate?
  • Will it have radial and axial loads?

When you have the answers to these questions, and have a better understanding about your application needs, call us at 775-333-5984. We would like to discuss your Pancake Servo Motor needs with you and to design the best Pancake Servo Motor to meet those needs.
