Rapid acceleration in case of heavy start-up, such as piston pumps, loaded tracks, high inertia loads, compressors with open valves, etc.
Meeting special cases, such as those mentioned above, with standard stock motors, with advantages of price, deadline, and delivery.
Allow the use of reduced voltage starting systems, such as star-delta switches, in normal cases, without compromising the perfect acceleration of the load.
Due to the high value of the maximum torque, they face, without a sudden loss of rotation, the momentary load peaks and transient voltage drops. This is essential for driving machines subject to large load peaks, such as crushers, calenders, etc.
The high torque-speed curve of WEG motors is not advantageous.
WEG motors with high torque-speed curves have a slow acceleration in case of heavy start-up.
WEG motors with high torque-speed curves can use reduced voltage starting systems without compromising the perfect acceleration of the load.
WEG motors with high torque-speed curves cannot face momentary load peaks and transient voltage drops.
b) WEG motors with high torque-speed curves have a slow acceleration in case of heavy start-up.
c) WEG motors with high torque-speed curves can use reduced voltage starting systems without compromising the perfect acceleration of the load.
d) WEG motors with high torque-speed curves cannot face momentary load peaks and transient voltage drops.

As vantagens dos motores WEG com alta curva de torque-velocidade são: - Aceleração rápida em caso de partida pesada, como bombas de pistão, trilhos carregados, cargas de alta inércia, compressores com válvulas abertas, etc. - Atender casos especiais, como os mencionados acima, com motores padrão em estoque, com vantagens de preço, prazo e entrega. - Permitir o uso de sistemas de partida com tensão reduzida, como chaves estrela-triângulo, em casos normais, sem comprometer a aceleração perfeita da carga. - Devido ao alto valor do torque máximo, eles enfrentam, sem perda repentina de rotação, os picos de carga momentâneos e as quedas de tensão transitórias. Isso é essencial para acionar máquinas sujeitas a grandes picos de carga, como britadores, calandras, etc. Portanto, a alternativa correta é a letra "c) WEG motors with high torque-speed curves can use reduced voltage starting systems without compromising the perfect acceleration of the load."
