Specifications:
The ELTE PE3 4/2 (often denoted as 4/2 or 42) is a precision high-frequency, three-phase asynchronous AC spindle motor / electrospindle (rather than a traditional synchronous servo motor) manufactured by ELTE srl in Italy. It is widely used in CNC machinery for high-speed routing, milling, and wood, plastic, or light alloy processing.
The specifications corresponding to your exact parameters (0.35 kW, 380V) represent its operating profile at a lower frequency step (typically 100 Hz to 115 Hz). The standardized technical specifications for the ELTE PE3 4/2 spindle series include:
