W40 – OPEN INDUCTION MOTOR
WEGINDO / PRODUCTS / ELECTRIC MOTORS / W40 OPEN INDUCTION MOTORS
The W40 Open Drip Proof Motors is a general-purpose line designed for environments where dirt and moisture are minimal. The W40 cast iron frame is designed to provide maximum ventilation and heat dissipation, offering low vibration levels, high mechanical stiffness and durability.
Application:
Widely used in applications such as compressors, pumps and chillers, the W40 line meets or exceeds the efficiency levels determined by International Standards and the minimum efficiency level programs in force worldwide.
W40 The Most Cost-Effective Industrial Motor
The W40 motor is an effective option for applications which do not require a high degree of protection. Due to its open enclosure, the motor design permits higher output levels to be achieved when compared with totally enclosed motors, resulting in a cost-effective solution for driven equipment.
The motor enclosures are carefully designed with high-techsimulation tools to ensure low sound pressure levels, even with the high amount of air circulating inside the casting.
WISE® WEG Insulation System Evolution
The WEG, WISE® insulation system (WEG Insulation System Evolution) has resulted from using enhanced insulation materials during the production of the electric motor insulation.
The WISE® (WEG Insulation System Evolution) is an advanced motor insulation technology developed by WEG to enhance performance, particularly in demanding applications such as those using Variable Frequency Drives (VFDs) or Variable Speed Drives (VSDs).
