R911293928
The R911293928 (MHD115B-024-NG1-RA) is an industrial servo motor fabricated by the esteemed firm Bosch Rexroth Indramat, renowned for its pertinence to digital servo feedback mechanisms. The specification categorizes it as having a frame size of 115 with a frame length labelled as B. Morphological dimensions measure the motor housing at approximately 431 millimeters, while the plain shaft itself extends around 80 millimeters outside the predominant motor housing with 38 millimeters in diameter, augmented by a shaft seal. Notably, the shaft options for MHD motors also include a key. This flange-mounted motor has an installation framework that encompasses a 192 millimeter motor flange equipped with four 14 millimeter mounting holes.
The R911293928 (MHD115B-024-NG1-RA) motor employs two distinct methods of cooling - natural convection and surface cooling. While natural convection capitalizes on ambient air flow, surface cooling leverages an increased airflow facilitated by a cooling fan. Deciphering the capacity, natural convection offers a constant torque at standstill at 50Nm with 60K overtemperature and 57Nm with 100K overtemperature. On the contrary, surface cooling delivers a steady 75Nm torque. With the rated speed indexed at 2000 RPM, this motor is supplemented with a 70Nm holding brake. Enclosed on the right side of the housing, the power connector enjoys an IP65 protection category. Weighing 40 kilograms, this apparatus mandates professional installation.
