In the directdrive system, the bowl is driven directly by an integrated, frequency-controlled, three-phase motor
and is infinitely adjustable--efficiency is improved along with significant energy savings.
He found a popped circuit breaker for one phase of the three-phase motor
for the right wingfold actuator.
The new drive system includes an infinitely variable three-phase motor
When only a single phase of a three-phase motor
load was monitored, the watt meters measured within 5.
The machine is powered by a three-phase motor
with electrically adjustable delivery pumps, applying a modular, three-stage concept with parallel functions.
5-hp, 220V/440V, three-phase motor
and a 1-hp, 220V/440V, three-phase scoring motor; a 4-3/4-in.
According with the enounced functioning principles in was realized a prototype of a rotary hydraulic three-phase motor
working with alternating flows, (Marcu, 2004), figure 4.
It runs any three-phase motor
1 to 20 kW without a sensor.
Fairchild Semiconductor (NYSE: FCS), a leading global supplier of high performance power and mobile products, has expanded its Short Circuit Rated IGBT product offering to provide motor drive designers higher efficiency, increased power density and improved reliability for three-phase motor
drive applications where low-losses and short-circuit ruggedness features are essential.
TI's new DesignDRIVE Kit offers an integrated design with full power stage to drive a three-phase motor
, easing evaluation of a diverse range of feedback sensing and control topologies.
The conventional hydraulic pumps consist of a fixed-speed, three-phase motor
with electrically adjustable, variable-volume pumps (Bosch Rexroth DFEE types), applying a modular, three-stage concept with parallel functions (Fig.
They combine a compact size (105 x 60 x 125cm) with a powerful three-phase motor
for high performance cleaning, even in space-restricted production areas.
