Most AC motors are induction motors. Induction motors are favored due to their ruggedness and simplicity. In fact, 90% of industrial motors are induction motors.
Nikola Tesla conceived the basic principles of the polyphase induction motor in 1883 and had a half horsepower (400 watts) model by 1888. Tesla sold the manufacturing rights to George Westinghouse for $65,000.
Most large ( 1 hp or 1 kW) industrial motors are polyphase induction motors. By polyphase, we mean that the stator contains multiple distinct windings per motor pole, driven by corresponding time-shifted sine waves. In practice, this is two or three phases. Large industrial motors are 3-phase. While we include numerous illustrations of two-phase motors for simplicity, we must emphasize that nearly all polyphase motors are three-phase. By induction motor, we mean that the stator windings induce a current flow in the rotor conductors, like a transformer, unlike a brushed DC commutator motor.

Wall Street’s equities titans are in the midst of an expensive technological arms race. Here’s why
Posted by Derick Lee in category: futurism
The major forces shaping equity markets — regulation and technology — are to blame. In the past decade, trillions of dollars moved from active to passive strategies such as index funds, while quants and high-speed firms have taken over more volumes in daily trading.

5 Animals & 1 Superbug That Can Freeze, Thaw & Live
Posted by Paul Battista in category: futurism
As an Earth Touch crew leaves sunny South Africa behind to do some serious chilling out in Antarctica (check out their journey to the bottom of the world!), we’ve been thinking about some of the extreme adaptations necessary for survival when temperatures plummet below zero. From powerful antifreeze to crazy cryogenics and dehydration verging on death, these animals (and one amazing bacterium) have evolved some impressive tactics for sub-zero survival.
