Changing to the \u03c4iD roll capable of high rotation accuracy and large torque output eliminated the need for the problematic speed reducer, enabling long-term maintenance-free operation.<\/p>\n<\/div><\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n

[Problem] The customer uses a rolling contact-type speed reducer because of the need to drive a large roll smoothly at a large torque, but they have suffered from occasional failures.<\/h2>\n\n\n\n

The problem with the customer’s existing film production equipment is the stoppage of the production line due to an abrupt failure of the speed reducer. Every time a failure occurs, the production line needs to be stopped for repair or replacement, inevitably leading to decreased yields. The motor is required to have high rotation accuracy and large torque. So, when selecting the manufacturer of the direct drive motor that would replace the existing motor, the customer called for the ability to meet customization needs flexibly.<\/p>\n\n\n\n

[Proposal\/solution] Replacing the existing motor with the \u03c4iD roll achieved maintenance-free operation and improved productivity.<\/h2>\n\n\n\n

We proposed the introduction of the \u03c4iD roll, a direct drive motor that does not require the use of a speed reducer. With the speed reducer gone, which was the source of failure, the customer is no longer forced to stop the production line, thus making it almost maintenance-free. An increased line operation rate has improved productivity, bringing an improvement in yields among other benefits. Since the customer requested that the equipment have high rotation accuracy and large torque, we customized the motor to reduce speed ripples and support large torque.<\/p>\n\n\n\n
