Pulse Width Modulation (PWM)
... Since the motor is at full voltage during the ON pulse, the motor runs at full torque during the ON pulse. A 25% duty cycle reduces the power applied to the motor close to 25%, yet the speed may not be reduced to 25% of the maximum speed. A PWM signal is at a fixed frequency. A very low PWM fr ...

Three-phase electric power
Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-phase system is usually more economical than an equivalent single-phase or two-phase system at the same line to ground voltage because it uses less conductor material to transmit electrical power.The three-phase system was independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström and Nikola Tesla in the late 1880s.
