Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...

Combining ECM calibration with a diesel delete kit removes the EGR and DPF systems entirely, allowing the tune to operate ...

Before we dig into this subject matter, we'd like to preface what will follow with some background comments. We've had hands-on experience designing intake manifolds and exhaust headers using the ...
