The graph shows that at 16 microsteps/full step, the incremental torque for one microstep is less than 10% of the full-step holding torque. The lure of microstepping a two-phase stepper motor is ...

Measuring torque when installing threaded fasteners is the best indicator of future joint performance, right? Actually, bolt tension is a better performance indicator, but measuring torque is far ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Paccar is taking the next step toward an integrated power train with the launch of a proprietary drive axle optimized for line haul applications. Offering axle ratios of 2.47 to 3.7, Kevin Baney, ...

In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...
