Product Description

Insulation class: Class F

Insulation withstand voltage: 1500V for 1 minute

Insulation resistance: 10MΩ or more (500VDC)

Other structure: outer rotor type

Excitation method: 3-phase

Power supply: 200-230VAC

Others: Nominal torque is the value when installed on a metal base with sufficient heat capacity. The position resolution is the recommended value and is set according to the drive. The mechanical accuracy of the load mounting surface is the axial deviation and radial deviation of the mounting surface.
