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.
