Specifications of the dedicated PM motor [MM-GKR motor]
X indicates the direction of the motor's output shaft, and Y indicates the direction vertical to the motor's output shaft. Usually, the indicated value is of the
non-load side bracket where the vibration is the greatest.
Bearing is subject to fretting while the motor is stopped. Suppress the vibration to about the half of the permissible value.
The standard motor may not be used under the condition where it is constantly exposed to oil mist, oil, or water. For the details, please contact your sales
representative.
"V10" means that the vibration amplitude of the single motor is 10m or lower. The following figure shows the installation orientation of the motor and
measurement position at the vibration degree measurement.
For the permissible load on the shaft, refer to the following figure. On the shaft, do not apply a load exceeding the value in the table.
Each value in the table shows the permissible value for the single load application.
