Frequently Asked Questions

What flange and centering diameter are used?

The motor features a 192 mm standard flange and a 130 mm centering diameter. The dimensions guarantee compatibility with standard coupling and mounting hardware.

How is the shaft configured in PP0 RN?

The shaft is keyed and sealed to prevent axial play and ingress. The key geometry ensures rigid torque transmission while the seal protects against contaminants.

What is the connector orientation on the housing?

The power connector is mounted on the motor’s right side relative to the shaft. The lateral layout influences cable routing and cabinet space planning.

How does the frame length “D” influence shape?

The “D” length provides extended rotor length and mass for torque capacity. The extended frame must be accommodated in machine depth and enclosure design.

How does housing finish affect integration?

The housing uses a black prime coat varnish to resist corrosion and maintain insulation. The finish ensures consistent performance in industrial ambient environments.
