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.

Departments

Bearings and Motors and Gears (Publishers Page)
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.
