W22 low-voltage
electric motors made of gray cast iron
for general use
.
W22 low-voltage electric motors for general use are extremely robust, as they are made of gray cast iron and designed to provide not only significantly lower energy consumption, but also lower noise, lower vibration levels, higher reliability, easier maintenance and lower operating costs.
The W22 series of electric motors offer better energy efficiency, performance and productivity, bringing maximum benefits to the customer.
Applications:
Pumps, compressors, fans, crushers, conveyors, mills, centrifugal machines, presses, elevators, packaging equipment, grinders, etc.
