SEW 380‑400Y Motor Voltage Code Unit

Module Feature

380‑400Y is SEW motor nameplate voltage marking. It indicates stator winding adopts star(Y) connection, rated working voltage range 380‑400V three‑phase AC. This voltage configuration is widely used for SEW standard DRN series geared‑motors, suitable for conveyor, mixer and general industrial driving equipment.

Working principle

Stator windings are connected in star mode. Three‑phase AC power supplies to winding terminals to generate rotating magnetic field, which drives rotor to rotate and output mechanical torque. Star connection adapts 380‑400V industrial three‑phase power grid.

Onboard components

Motor stator winding, terminal board for star‑delta conversion, terminal block, insulation assembly.

LED indicators

No onboard LED indicators. Motor running status judged by temperature, noise and vibration.

Hardware self‑diagnosis

Check terminal connection tightness, measure winding insulation resistance, monitor motor housing temperature, inspect abnormal noise and vibration.

Programming software

No configuration software, fixed winding connection mode, purely electrical specification marking.

Electrical & Process Parameters

Installation

Wire motor terminal board strictly follow Y‑connection diagram. Confirm input three‑phase voltage falls within 380‑400V range before power‑on. Fasten terminal screws to prevent over‑heating caused by poor contact.

Interface

Motor winding terminal board, three‑phase power input terminals.

Diagnostic

Motor overheat: wrong connection mode or voltage out‑of‑range. Unbalanced current: loose terminal wiring. Motor cannot start: phase missing or wrong wiring on terminal board.
