Custom 6600V electric motor for thermal power plant in Japan

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.

• 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.
