In conjunction with the Best by Design awards, we invite you to cast your vote for the Motion Medalist awards. Presented here are components featured over the last year of Motion System Design — products that span motion control and power transmission design. Simply go to motionsystemdesign.com/bestbydesign (or email us at firstname.lastname@example.org) to rank these products by how useful you think they are. Top-rated products will be announced this spring.
Retaining rings take up less space
Hoopster retaining rings fit into much shallower grooves than regular snap rings or retaining rings, and are suitable for light to heavy loads.
For thin-wall tubes; low profile, precision circularity, small radial size, high thrust capacity
Will not twist or deform under load as do conventional retaining rings
Controller is programmable
Carbon and 302 stainless steel in sizes from 3/8 to 3 in.
Innovator: Smalley Steel Ring Co.
The Productivity3000 PAC is a modular, rack-based system of up to 116,000 I/O points with local, expansion, and remote I/O bases and a full line of discrete, analog, and specialty I/O modules.
Terminal blocks provide universal link
P3-550 CPU features 50-Mb memory and seven ports that support USB, Ethernet, and serial devices
Two power supplies (ac and dc) provide isolated 24, 5, and 3.3 Vdc to PAC bases
Free ProductivitySuite software has tag name-based programming
Shrink-disk collar make mounting easy
YBK series of feed-through terminal blocks use a tension-clamp connection for fast wire terminations and reliable connections.
DIN rail mountable and available in gray, blue, red, yellow, beige, and green
Slip rings transmit over spinning connections
Accessories include end plates, end brackets, cross connectors, and marking tags
For chemical, plastics, and packaging industries, those with control and electrical panel wiring
Innovator: Omega Engineering Inc.
Automatic code generator
BLC Bearlok locks power-transmission components to keyless shafts more securely than conventional collars.
Balanced for high-speed applications; withstands abuse; suited for critical stops and where access tangent to the shaft is unavailable
Alloy steel, black-oxide coated; bores from 0.75 to 2.50 in.
Serial communications reduce wiring
Positions, locks cam shafts, conveyor rolls, gears, and components requiring basic adjustment that transmit thrust and torque
Innovator: Whittet-Higgins Co.
Stainless-steel Prizm Model CK7206 is a seven-channel electro-optical slip ring that runs to 60 rpm with less than 1 dB of variation.
Precision bellows serve many functions
Single or multimode; no dead spots, bidirectional; attenuation less than 4 dB for any pass; gold alloy brush and ring surface contacts
Power Ring comes with 20 rings — rated for 5,000 V at 20 A; Single Ring versions available
Innovator: Moog Components Group
Smooth reducers: Hygienic and efficient
Simulink PLC Coder extends model-based design to help create source code in structured text (IEC 61131-3 ST) using Simulink models.
Universal interface integrates code generated by Real-Time Workshop and Simulink PLC Coder in Automation Studio; quickens development
Users can generate ANSI-C or structured text code
Line shafts and couplings transmit power
Errors detected early; tested algorithms go to industrial controller
Innovator: B&R Industrial Automation Corp.
MotionNet serial-communication networking provides I/O and motor control, CPU emulation, and reduces wiring.
Transfers four bytes of data in 15.1 µsec using cyclical communication to control input and output
64-pin chip controls up to 64 local devices
I/O with four 8-bit ports/device, buffer, cyclic transfer; control for stepper or servomotor
Innovator: Nippon Pulse America Inc.
