SIMOTICS HV C water-jacket-cooled

Very space-saving and efficient in harsh environments

SIMOTICS HV C water-jacket-cooled

The SIMOTICS HV C water-jacket-cooled is the new high voltage motor, which as a result of its optimized cooling concept, has been made even more compact – making it the ideal solution for applications where space is restricted. At the same time, the motor is predestined for extreme installation locations as dirty, aggressive and salt-laden air is reliably prevented from entering the motor. Further, it allows the dissipated heat to be recovered and used in the process itself.

Additional optimization has also resulted in a lighter design, even quieter operation and a further improved vibrational behavior, which ensures smooth operation and in turn maximum service life for the plant or system. These motors also set themselves apart as a result of the extremely short delivery times – and high on-time delivery for this power class.
