Bearings and Motors and Gears

Oh my. It's been another busy month here at Power Transmission Engineering, and we have another full issue for you. This time around we have a focus on bearings, with plenty of great examples of applications and technology from the world's leading manufacturers. Of course, bearings are essential to power transmission and a core subject we cover every issue. But when it's the focus, we like to attack the subject from multiple different angles.

Comparing Data Sources for Condition Monitoring Suitability

Condition-based maintenance requires detailed state knowledge, often acquired by means of sensors.

Various Coil Configurations Used in Coreless Motors

Three-dimensional finite element analysis (FEA) simulation and research from published information is used to compare the features of various coil configurations.

Hybrid Transverse Flux Magnetic Motors - How to Measure Parameters

These versatile, low-cost and high-torque motors may be used open loop or as full servos - and several levels in between. The motor stator laminate designs divide these motors into those optimized for full stepping, and those optimized for micro stepping and servo operation. These differences can be easily measured with basic meters and oscilloscopes. Motor to motor variations can also be easily measured, and motor inductance at nominal speed and current can also be determined.

Timken Addresses NVH Requirements in Bearings

As NVH technology advances, so do the tools that allow engineers to study, test, and manufacture bearings capable of delivering high-performance and quality.

Engineering Showcase - Bearings

In this special advertising section, Power Transmission Engineering features several of the world's leading bearings suppliers and their latest technology.

Schaeffler Readies Launch of End-to-End Wireless Sensor Solution with OPTIME

A discussion of the evolution of condition monitoring for bearings and the upcoming introduction of company's next-generation condition monitoring platform.

The Maintenance of High Quality and Taste

Valves help control temperature, pressure and viscosity for alcohol fermentation.

Motors in Space

Components like motors, bearings and drives are subject to harsh environments on Earth, but they must be at the top of their game to enjoy space travel. Recent applications from Maxon Motors (Return to Mars) and the University of Michigan (Robotic Legs) illustrate the incredible requirements it takes to handle applications in space and how these components can be utilized here on Earth.
