W22Xec - INCREASED SAFETY MOTORS

Increased safety “Ex ec” motors are designed to prevent the occurrence during normal operating and certain specific abnormal conditions of arcs, sparks & excessive overheating of all inner and outer surfaces of the machine which could reach the self ignition temperature of the surrounding potentially explosive atmosphere. In the case of “Ex tc” machines, the maximum surface temperature of the enclosure is defined either:- through measurement, under normal operating conditions, of the external surfaces of the machine with no dust layer, or- determined for a given depth layer, “TL ”, of dust surrounding all sides of the equipment (a maximum depth may be specified by the manufacturer). 

VFD Application
W22Xec motors are also certified for operation with Variable Frequency Drives:

• Thermal protection embedded in motor windings.
• Separate rating plate indicating permissible operating parameters under variable speed conditions.
• Must respect WEG derating curves / conditions defined in ATEX & IECEx certificates.
   

SYNCHRONOUS MOTORS

Synchronous motors WEG offers complete industrial solutions, providing the market with products developed along with specialized international consulting companies. Among the products, synchronous motors stand out as they are being increasingly more used in a variety of applications due to their special operating characteristics. High efficiency, power factor correction, high torques and low starting currents, constant speed under load variations, low operating and maintenance costs are the main reasons why synchronous motors are the most indicated drive for different types of applications.

VARIABLE FREQUENCY DRIVES & SOFT STARTERS 

CFW11
With high technology for control of three-phase induction motors and permanent magnets synchronous motors - Magnet, the CFW11 Series achieves the performance increase for the most complex drive systems. Design exclusive for industrial or professional use, the CFW11 presents many innovations adding significant benefits to customers, a lot for its simplicity of installation and operation, based in the Plug-and-Play philosophy also allowing simple and quick installation of its accessories.

MVW01 - Medium Voltage Drive
Applied for a wide range of industrial applications that require variable speed control, such as compressors, pumps, fans, conveyor belts, mills, etc. or to start high power motors (synchronous or asynchronous).

The MVW01 third generation is an efficient and reliable solution that not only enables process speed control but also provides energy savings, high efficiency, reducing operation & maintenance costs as well as the total cost of ownership (TCO).
