MENZEL MOTORS
CUSTOM 6600V ELECTRIC MOTOR FOR THERMAL POWER PLANT IN JAPAN
MENZEL was asked to manufacture a custom 6600V electric motor to drive a multi stage condensate water pump in a thermal power station . The existing motor needed to be replaced quickly . In just four weeks MENZEL planned , built and delivered an three-phase squirrel cage motor with IC 616 cooling and IP 55 protection .
The requirements : Precision and speed
The customer not only wanted a motor that could be seamlessly integrated into the existing system via plug-and-play , but also one that could be implemented quickly . MENZEL was able to complete the motor in just four weeks .
One of our stock motors in the required size formed the basis . However , the following adjustments still had to be made :
• Precision work on the rotor shaft : conversion to shaft nuts with left-hand thread and laser welding of the keyway .
• Changing the cooling system : Conversion from IC81W to the IC616 system .
• Adaptation of the direction of rotation : including different inner fan wheel Accompanying tests : Extensive tests in the load test field to ensure the highest standards .
Technical data of the AC-Motor
• Type : MEBKSLF 500-04-011 AC-Motor
• Motor application : Condensate water pump in thermal power station
• Rated power : 970 kW
• Rated voltage : 6600 V
• Rated speed : 1487 min-1
• Type of construction : IM V1
• Protection class : IP 55
• Cooling type : IC 616
• Weight : 7160 kg
The delivery : Precisely to the destination
The finished squirrel cage motor was transported to Japan by plane in order to meet the critical deadline . Installation and commissioning took place at the thermal power plant , where the motor now reliably drives the multi stage condensate water pump .
This project is a prime example of our strengths :
Custom solutions in the shortest possible time
Efficient communication and close coordination
Highest technical precision , made in Germany
• Adapterplate and different mechanical modification : for a plug and play type fixing between the motor an the pump
The implementation : precision meets efficiency
During the planning phase , we went through several changes and special requirements . Thanks to the close cooperation between the customer , our project engineers and our production department , we were able to developand agree the technical solution quickly . Our ability to meet technical requirements and commercial details in record time was particularly praised .
In addition , the motor was extensively tested in ourload test field . Where MENZEL successfully met all customer requirements .
