1 Analyzing Synchronous Belt Failure (October 2009)

If you’re replacing your belts more than once per year, it’s time to analyze your drive. From belt crimping damage to high belt installation tension to sprocket misalignment and adverse environmental conditions, this guide walks you through how to identify the reasons behind premature failure and makes recommendations on corrective and preventive measures.

2 Timing Belts and Pulleys - Operations (December 2016)

Synchronous drives are especially well-suited for low-speed, high-torque applications. Their positive driving nature prevents potential slippage associated with V-belt drives, and even allows significantly greater torque carrying capability. Small pitch synchronous drives operating at speeds of 50 ft/min (0.25 m/s) or less are considered to be low-speed. Care should be taken in the drive selection process as stall and peak torques can sometimes be very high. While intermittent peak torques can often be carried by synchronous drives without special considerations, high cyclic peak torque loading should be carefully reviewed.

3 Advanced Belt Drive Systems (June 2019)

Enhancing Safety, Quality, Delivery and Cost.

4 Hovercraft Technology Taking Us Back to the Future (December 2015)

There are few things in this world that elicit such a gleeful, childlike sense of wonder as does the word “hoverboard”.

5 Guide to Selecting and Replacing Synchronous Belts (June 2016)

Just as we now consider rotary dial phones archaic, so are many installed synchronous belt drives. That they continue to operate is testimony to their durability. But that should not prevent you from taking advantage of newer synchronous belt drive technology that can improve both equipment design and field installations.

6 Guide to V-Belt Selection and Replacement (June 2017)

V-belts look like relatively benign and simple pieces of equipment. They're basically a glorified rubber band, right? Need a replacement? Just measure the top width and circumference, find another belt with the same dimensions, and slap it on the drive. There's only one problem: that approach is about as wrong as you can get.

7 Pushing Forward with Belts and Chains (June 2018)

The technology continues to evolve in chain- and belt-driven systems

10 Belt and Chain Technology (October 2020)

The following article examines some of the most recent product and industry news related to belts and chains, including news from Continental, Gates, Igus and Tsubaki.

11 Improperly Testing Belt Tension Can Easily Damage Small Motors (February 2019)

Most of us want to just instinctively squeeze a belt between a pair of pulleys to test the belt tension. What is not as instinctive is just how much force such a procedure can put on the shaft -- often significantly past the manufacturer's rated limits for small motors. This can cause damage to both the shaft and the bearings.

12 Total System Efficiency (February 2010)

Much of the industrial energy being consumed by systems is wasted through inefficiency. For this article, a system will be defined as the following components working together: electrical input power, variable frequency drives, induction motors, gearboxes and transmission elements (chains, belts, etc.).

13 Drive and Motor Basics (October 2013)

A discussion of the basics in DC drives, DC motors, AC drives, AC motors and synchronous motors.

14 Motoring Ahead (August 2011)

Synchronous motors controlled by variable speed drives are bringing higher efficiencies to industrial applications.

15 The Reluctance Motor Springs Forth (August 2014)

There are three major types of reluctance motors: all three reluctance motors are non-permanent magnet, brushless motors. They are synchronous motors with a non-linear relationship between torque and current. The variable-reluctance step and switched-reluctance motors utilize the principle of magnetic attraction by inducing magnet poles within the soft-iron rotor, and by energizing a set of coils wound around stator teeth resident in the laminated stator. These two reluctance motors must be sequentially excited to achieve continuous, steady-state rotation. The design of all reluctance motors requires finite element analysis (FEA) software.

16 Motors without Rare-Earth Magnets: What Are the Options (October 2019)

Lower-cost motor technologies exist that can be an attractive alternative to neo-based BL PM motors - and are not subject to unpredictable supply chains
