Specifications
Low noise and low vibration for stress-free operation
Premier energy-saving design in the industry
Easy to maintain
Maintenance tasks that require the machine head to be tilted back
have also been made safer. A safety sensor is provided to stop the
motor from operating while the head is tilted, even if the treadle is
depressed.
• Machine head can be tilted back easily
The complete dry-type head uses a lubrication-free rotary hook, and no
oil is used around the needle bar, thread take-up or rotary hook
mechanism. As a result, no lubrication is required at all.
• No lubrication required (45

)
The running time for the sewing machine is recorded, and when it is
time for the greasing maintenance that is indispensable for dry head
sewing machines to be carried out, a notification appears automatically
on the panel. (Use only special Brother grease to ensure excellent
durability.)
• Automatic greasing notification
The oil level inside the gearbox can be checked visually. In addition,
the gearbox has a heat-discharging construction with fin.
• Gearbox oil level can be checked at a glance
The sewing machine frame is highly rigid, and
computer analysis has been used for designing
everything down to the smallest detail, to
create a shape which produces less noise and
vibration. This reduces operator fatigue and
greatly eliminates stress.
The brand new built-in direct-drive motor has an
optimized design that utilizes magnetic field
analysis, and is the most compact motor of its
type in the industry. And instead of using a
V-belt, the drive power is transmitted directly to
the mechanisms with no losses, so that any
losses in energy are reduced to an absolute
minimum. This new motor has an energy-saving
performance that is a further improvement on
previous direct-drive motors. Compared to
V-belt driven systems (AC servo motors),
losses in efficiency are reduced by
approximately 40% (compared to the previous
Brother model), meaning that this model tops
the industry in energy saving.
