Invented in 1962, brushless DC (BLDC) motors are now commonly used in multiple applications such as robotics, industrial automation, autonomous ground vehicles and personal transportation devices. Standard-frame DC motors are usually integrated into several end products; however,situations may arise where constraints in weight, inertia, volume or packaging require use of alternative solutions, such as frameless BLDC motors. There are benefits and challenges for integrating frameless BLDC motors. SDP/SI is a worldwide developer, manufacturer and supplier ofprecision motion control systems and components witha partnership with Nidec Motion Control, an industry leading manufacturer of frameless BLDC motors.

In high-torque applications, ensuring your rotating components are securely fastened is critical to your operational safety. It''s also something you shouldn''t have to think twice about.

That''s why the innovative Fairloc hub design, developed by Stock Drive Products/Sterling Instrument, provides design engineers, manufacturing engineers and OEMs with a secure way to increase concentricity and reduce alignment issues, maintenance, and assembly time on new and replacement components.

Our Fairloc® Integral Fastener is a clamping device placed right on the hub of timing pulleys, gears, couplings and more. Using set screws to clamp components can sometimes mar or damage your shaft. Fairloc® helps to prevent that because it camps components without the use of set screws. It also allows for quick and easy adjusting and readjusting of components on shafts.

When a standard product won''t meet your requirements we can provide alternative solutions through custom design and manufacturing. Our engineering and manufacturing teams will partner with you throughout the entire process. By providing design, development, manufacturing, assembly, and testing in one location. we can ensure the end product will meet your expectations.

Sterling Instrument (AS9100 Registered Manufacturer) offers a new, low backlash variant on its existing line of multi-plate in-line slip clutches. Both versions feature an all mechanical design, which makes them considerably cheaper than electromechanical alternatives. The slip plates are layered with friction pads in between, and an adjusting nut sets the slip torque by squeezing the plates together. The outer plates are tabbed to fit into the output housing and the inner plates are connected to the input hub, so that the two ends disengage from one another upon slipping. These clutches are commonly used for overload protection to prevent injury and machine failure, but have a wide variety of other applications such as tension control and positioning retention hinges like the ones in reclining chairs.

It was designed and arranged by Andrea Davide, a New York based artist who specializes in creating unique metal sculptures. Robert Lindemann, the recently retired Vice President of SDP designed the mechanical drive system that allows the gears to move properly. The motion is driven by an AC gearmotor inside of a large rectangular base, which rotates the smaller circular base on top. The two sprockets attached to the base are driven by bevel gears in mesh with a larger stationary bevel gear inside the base. The sprockets in turn drive the roller chain wrapped around the clear circular disks. The rotation of the circular disks about their center shaft is translated to the center gears inside, which in turn moves the entire geartrain.
