The industry's most efficient energy savings
The internal brand-new direct drive motor, designed
through with magnetic field analysis, is the most compact
in the industry. As the motor's driving force is transmitted
directly to the mechanisms, energy loss can be reduced to
the minimum. Electrical power consumption has been
lowered to approximately 50% of that of our conventional
V-belt driven system (AC servo motor). The Z-8550A and
Z-8560A are the top energy-saving models in the industry.
Good response, comfortable sewing
An operator's control is essential for lock stitching
process. The direct drive system responds to an
operator's control very well and performs sewing fit to
his/her intention.
No needle deflection, no position slippage, even at high-speed sewing
With the electronic zigzag stitchers, the needle moves
perpendicular to the material so that needle deflection does not
occur even at high speed sewing. Furthermore, the pulse motor
with servo control, adopted for the needle bar mechanism,
prevents position slippage.
Low noise and low vibration allow stress-free operation
The high-rigidity frame and well-balanced parts
details realized by computer analysis have
reduced the noise and vibration to the minimum.
This frees operators from fatigue and stress.
