Cool motor

The W22 motor features a new cooling system that also reduces noise level. 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 cooling system contributes to lower winding and bearing temperatures, resulting in longer life.

The W22 motor features a new cooling system that also reduces noise level. 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 cooling system contributes to lower winding and bearing temperatures, resulting in longer life. The terminal box features increased internal space and easier cable handling and connection. The dimensions are optimized to provide more space to the power supply cable inlet and to auxiliary connectors. The terminal box can be mounted on top, left or right side of the motor on frames 447T and above for easy field modification.
