|Redesigned to provide improved air flow through all motor frames keeping low operational temperatures and assuring reliability and extended lifetime. The aerodynamic design of the fan cover increases effective airflow, thus minimizing
losses due to the recirculation of air between fan and fan cover. The fan was designed to provide strength and reduced noise level. Motor terminal box and eyebolts were repositioned on larger frames to allow better airflow.
The new W22 cooling system also contributes to:
