High Energy Saving
Better response to the pedal operation has been realized at sewing start and
stopping of sewing with new original motor and control box. Time required to
reach the maximum sewing speed is approximately 25% less compared to those
driven by the V-belt driven system(with an AC servo motor), or approximately
7% less to T-8421B.
The needle up stop and needle down stop positions can be set,
so as to enhance the productivity.
New Brother-developed motor realized higher energy saving. The power
consumption of the machine is approximately 61% less than that with the V-belt
driven system(with an AC servo motor) and approximately 12% less than that
of T-8421B.
It boasts top-level energy saving in the industry, enabling machines to work
twice as many as machines even where the electricity supply is limited.
Better Response and More Comfortable Sewing
A downsized and flat control box can
provide a larger leg space to be utilized.
The efficiency of the operation has been
improved. It will also help to alleviate a
sense of fatigue of operators who have
to sit in front of the machines in a fixed
posture for long hours.

Prevents Bird's Nests
Stabilized motor stop position at the
time of thread trimming reduces the
bobbin racing. This prevents the bird's
nests. It is a big advantage when
sewing the light materials.
