Do you have the right Rotary Servo for the job you have to do? Prime Drives manufactures Rotary Servos and will work closely with you to ensure you have the right Rotary Servo for your application needs. Before deciding if you have the right one, however, it is important to understand what a Rotary Servo is, what applications they might be used for, and what benefits you can receive from using Prime Drives’ Rotary Servos.
What is a Rotary Servo? Also called a Direct Drive Servo, a Rotary Servo is a precision rotary positioning device. It is most often used in robotics, for antenna pedestals, and in medical patient beds. Rotary Servos are also used in machines which automate the placement of integrated circuits, capacitors, resistors and diodes. These are then placed on printed circuit boards and will become computer motherboards as well as the brains behind today’s top smart TVs or your iPad.
What applications use them? Rotary Servos are used in the following applications:
Automated pick and place machines
Visual inspection machines
Medical patient beds for oncology detection and treatment
Entertainment/film industry for cameras
Military applications would include gun turrets on helicopters and tanks as well as cameras on unmanned aerial vehicles (UAVs)
Why would someone choose one type of Rotary Servo over another? Basically, Rotary Servo is a general term. It can be applied to any of the following: Direct Drive Servo, Parts Sets Servo, or simply a basic rotary table driven by a servo motor. The type of applications for which the Rotary Servo is needed will determine the type the engineers select.
How are the Rotary Servos from Prime Drives different from the competitors? What are the benefits of using them?
We have designed our Rotary Servos to be flexible offering more gear ratios and diameters than others available in today’s marketplace. This is what distinguishes ours from our competitors.
We design our Rotary Servos with four distinct diameter tables. These range from 4 inch diameter to 12 inch diameter. There are 24 various ratios within each of these diameter series.
We offer customization of the table. This can include a machined top plate which eliminates the need for an adapter plate. We can also add custom home sensors. Customization can also be made for the thru hole. This customization alleviates cable management issues or allows for laser pass thru capability.
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.
