Sealed for life bearings
Drive-end bearing cap
Power and control cables 500 mm long
Electronic protection: overload, over temperature and locked-rotor.
Fire mode (Override & Maximum speed mode)

Notes:

1. Totally Enclosed, Non-ventilated. Output limited to 0,65 kW. Refer to WEG for electrical data.
2. Totally Enclosed, Air Over rated. Minimum airflow over motor frame and drive cover 5 m/s.
3. The W30 Smart EC reaches the future IE6 level of efficiency, the highest in the market - considering 20% less losses then IE5 according to the standard IEC TS 60034-30-2 - for variable speed electric motor.

Optional Features

Passive PFC (Power Factor Correction)⁴ - Single-phase
Pad mounting (4x90° or 3x120°) and FF-165 flange
Slinger seal for vertical shaft-up mounting
115 V input power supply (up to 0,55 kW) - Single-phase
Decentralized drive and motor mounting
Customized shaft ends
Double shaft ends (only with decentralized drive version)
External controller with display to adjust maximum and instantaneous speed values

Notes:

4 - W30 Smart EC require the use of an external filter (passive PFC) to comply with the harmonic current emissions requirements of EN 61000-3-2. Refer to WEG for further details.
