WEISS built-in spindle motors from CNC Design eliminate couplings, belts, and gearboxes to reduce spindle inertia and increase accel/decel times for increased productivity. Main features include low vibration, compact size, light weight, high power density and available in customised design.

The absence of drive traverse forces permits extremely high accuracy on workpiece due to smooth, accurate spindle motion even at very low speed. WEISS built-in spindle motors are available as synchronous motor and asynchronous motor. They can be integrated with Siemens servodrive or inverter.
