Oversizing often happens when engineers try to match the inertia between the load and the motor rotor, so that they can tune the drive’s velocity, torque or position loop relatively tightly to meet ...

Here’s how power losses and inertia matching affect the efficiency of linear drives. The operating efficiency of linear drives is of growing concern to machine designers. Here's a look at three common ...

Boosting throughput while maintaining accuracy (or vice versa) is challenging. Most motor-powered motion systems require compliance correction as well Boosting throughput while maintaining accuracy ...

The case of a pulsating-load testing machine shows how to ballpark qualities that are important for deploying electric motors. Crankshafts in running internal-combustion engines pulsate as well as ...

Once the decision is made to use an electric motor in a new machine design, the next challenge is selecting the right motor and sizing it correctly for your application. This paper gives the tools you ...
