
The reduction gear equipped models do not have
the oil seal.

The oil seal model has an outline dimension different from the standard
motor.
For the details, please contact your sales representative.

For the applicable models and detailed specifications, refer to the sensorless servo catalog.


The above characteristics apply when the rated AC voltage is input from the drive unit (Refer to page 303). Output and rated motor speed are not guaranteed
when the power supply voltage drops.

The power supply capacity varies with the value of the power supply side drive unit impedance (including those of the input reactor and cables).

For a machine that produces unbalanced torque, such as a lift axis, the recommended unbalanced torque is the 70% of the rated torque or lower.

This is the ratio of the moment of load inertia to the moment of motor inertia under position control. If the load inertia moment ratio exceeds the described
value, please contact your sales representative.

This excludes the part where the shaft passes through. For the reduction gear equipped model, the protective structure is equivalent to IP44.
