Frequently Asked Questions
What are the flange and centering dimensions?
The motor uses a 192 mm flange with 130 mm centering diameter as standard. The dimensions facilitate coupling, gearbox alignment, and mounting brackets.
How does frame “112D” classification affect shape?
The “112” indicates the motor’s outer diameter class, and “D” refers to its axial length. The classification ensures dimensional compatibility with mounting standards and adjacent hardware.
What shaft design does the RN version use?
The RN configuration employs a keyed shaft with seal to transmit torque securely. The keyed geometry ensures coupling rigidity but demands precise machining of mating parts.
How does the motor’s length impact installation?
Its D-length frame provides added rotor mass and torque volume. The extended length must be accounted for in enclosure depth and adjacent clearance planning.
How does connector orientation influence system layout?
The power connector is on the motor’s right side relative to shaft output. The lateral orientation affects cable routing and accessibility in tight cabinet environments.
