Explore how Tesla reinvented the electric motor! From Nikola Tesla’s AC induction motor to cutting-edge IPM Synchronous Reluctance Motors, see how Tesla balances power, efficiency, and innovation to d ...

The importance of optimizing motor control for energy efficiency cannot be overstated, given that motors account for a significant portion of global energy consumption. This article delves into the ...

Here’s a detailed comparison of EPA range with the new permanent magnet (PM) motor versus the old induction motor (IM). Note that while combined range and MPGe improved around 10%, city MPGe ...

Optimized control of the induction motor can be achieved by directly controlling the slip value or slip frequency. For each induction motor there is a profile like the example shown in Figure 1. There ...

The goal of those efficiency standards is the conservation of energy and the economic justification. For regulators, one of the easiest things to measure is the motor’s efficiency, but it might be ...

“A motor that is three to four efficiency bands higher than today’s Premium Efficient (induction) motors will likely be a hybrid design,” says Richard Schaefer, senior variable-speed product ...

Typically, motor efficiency peaks at the motor’s rated point and decreases as operating speed or load diverges from the rated point. For example, a 5-hp NEMA Premium fan motor may be 89.5% ...

Many engineers look at NEMA Premium grade as the gold standard for induction motor efficiency. But technical innovations now make possible even more power-miserly designs. By now, most engineers ...

By replacing a standard, 200-hp motor that works at a 100% duty cycle with a premium-efficiency model, a plant could expect to see a reduction in its annual electric bill of $15,000 (Figure 5).
