The Marine and Oil & Gas industries are increasingly requiring the use of local content in equipment installed on platforms and support vessels. In order to meet this demand, WEG assists its customers to reach the local content levels in their projects, providing equipment with high level of nationalization. Using a 100% national workforce, and with the main parts of these motors manufactured at WEG, the WGM line reach high levels of local content.

The motors of the WGM line, water jacket cooled, were developed to meet the growing demand for compact, silent motors with high output/weight ratio.

Cooling The cooling system by water jacket of the WGM motors consists of water circulation through the end shields and frame. Besides allowing a more effective heat exchange between the motor and the water, the system reduces the temperature of the conducting materials and increases the output/weight ratio. This system allows maintenance of the heat exchange efficiency even at low speeds, which allows the use of VFDs in a wide speed range, including severe applications with constant torque requirements.The water jacket also minimizes the heat exchanged with the environment, reduce the bearings temperature and eliminates the need of forced ventilation, reducing maintenance and noise.

BearingsThe WGM motors have an exclusive bearing cooling system. That allows, the bearings to operate under reduced temperature, increasing its lifetime and reducing maintenance of the motors. As standard, the lifetime of WGM motor’s bearings is rated at 80,000 hours. Different configurations, such as sleeve bearings, can be supplied under request. Water TypeThe motor cooling channels are anticorrosive protected, suitable to operate with treated industrial water and complying with most of water specifications available in the industry. The project flexibility and the robustness of this motor line allows operating with different temperatures of water inlet and different types of additives, such as antifreeze and anticorrosive. In case of emergency, the motor can also be operated with sea water for up to thirty consecutive days; however, that can only be done twice along motor’s lifetime. After sea water operation, it is mandatory to clean the cooling circuit with treated industrial water.
