Speed vs torque curve
WebAug 23, 2024 · But why is a richer ratio better for more torque? (and thus more power) That's because rich AFR's burn faster.(until a certain richness) That means pressure is made quicker after TDC. And so more torque is made. And torque times rpm is power. With leaner ratio's that pressure occurs later, which doesn't enable the engine to make as much power. WebJun 1, 2015 · They are used for low-starting-torque loads, such as with centrifugal pumps and fans. NEMA C and NEMA D motors are used for applications that require high starting torque (e.g., positive-displacement pumps and compressors). Speed torque curve. The graph in Fig. 1 shows a typical speed/torque curve for a NEMA-B motor. Such curves …
