Kollmorgen has developed AKMH, a new vented connector in response to customer requests for a robust connector solution for their AKMHTM motors. The integrated pressure equalization feature on the AKMH makes the connector durable, according to the company. A hybrid power/feedback cable incorporates a tube that allows the motor’s internal pressure to equalize with the electrical cabinet of the connected drive.
Kollmorgen’s test data showed that internal pressure of a sealed AKMH during a thermal cycle ranges from -5.5 to +6.0 PSI. Allowing high pressure to occur inside the motor can cause premature failure of the motor’s seals and result in the failure of the motor due to water ingress in a wash-down application, which can be prevented by venting the motor in a wash-down environment.
