Company E manufactures various AGVs for the logistics industry. One of their main products is an AGV that lifts and moves shelves. Immediately after a model change, this AGV began to suffer from assembly defects. Director F of the company's development and design department explains:
"There was a problem with the quality of the servo motor used in the rotary table, and we were experiencing frequent assembly defects. We wanted to improve quality as soon as possible, so we started looking into replacing it with a servo motor from a reliable manufacturer."
However, a problem arose that caused the engineers a headache.
"Due to cost constraints, we could only replace it with a servo motor. Therefore, we needed a servo motor that could be controlled by the current amplifiers. However, there were limits to what we could do on our own, and it would have been difficult to replace the servo motor without technical support from the motor manufacturer," said Mr. F.
With the deadline approaching, Company E's engineers were busy coming up with solutions.
Searching for a solution, Manager F visited SANYO DENKI CO., LTD. 's booth at a technology exhibition and discussed the issue with the person in charge.
"SANYO DENKI CO., LTD. thoroughly inspects all of their products and provides stable products, so I thought they were a trustworthy manufacturer. I thought that by using SANYO DENKI CO., LTD. 's products we would be able to solve our quality issues." (Mr. F)
At a later date, a SANYO DENKI CO., LTD. sales representative visited Company E with the technical support team. The technical support team listened to the issues and confirmed the specifications of the current product in detail, then made a proposal based on the DC servo motor "SANMOTION K ( Reduced Cogging )".
"Because we were able to speak directly with engineers, rather than just with the sales staff, we were able to convey our detailed requests and smoothly select the motor. The evaluation of the servo motor also went smoothly, as we were able to mount a prototype on the actual machine and check its operation while adjusting the servo motor. Since the AGV lifts and moves shelves, stable movement is required, and the DC servo motor "SANMOTION K ( Reduced Cogging )" that was proposed to us seemed capable of achieving smooth and stable movement." (Mr. F)
Director F was also satisfied with the detailed customization suggestions made by the technical support team.
"We were worried about whether we could just replace the servo motor while leaving the control system intact, but one thing that was appealing about the SANMOTION K ( Reduced Cogging ) DC servo motor was that the control system could be used in the existing environment. They also customized the encoder to meet our desired performance. As a result, we were able to replace the motor without changing the size of the motor and keep the current system intact, which was a relief for all of our engineers." (Mr. F)
The results of the actual evaluation carried out at E Company were as expected, and the decision was made to officially adopt the system.
SANYO DENKI CO., LTD. continued to provide support, and E Company was able to successfully replace its servo motor.
"Since replacing the servo motors, there have been no more assembly defects and production is proceeding smoothly. With their high-quality products, speedy proposals, and technical support, SANYO DENKI CO., LTD. was able to solve technical issues that would have been difficult for us to solve on our own. We look forward to consulting them again in the future." (Mr. F)
