R911287620
The Bosch Rexroth Indramat R911287620 (MHD115B-058-NP0-AA) is a high-performance industrial servo motor that is adaptable to different cooling methods; natural convection and surface cooling. Natural convection relies on ambient airflow, while surface cooling uses a forced-air system produced by a cooling fan. Depending on the method selected, this motor exhibits different performance specifications: under natural cooling, the motor achieves 4000 RPM speed and 50 Nm standstill torque, whereas with surface cooling, the motor can achieve the same speed, but offers increased standstill torque of 75 Nm.
Varying characteristics also extend to momentary inertia of the rotor (0.00932 kg m2), rated speed (1500-4000 RPM), and torque (17-18.1 Nm). The R911287620 (MHD115B-058-NP0-AA) motor does not incorporate a holding brake, weighs 40 kilograms, and carries an IP65 protection rating. Other equipment includes a power connector to side A, digital servo feedback, and a main shaft with a keyway and seal. The motor mounting is facilitated by holes on the flange, which measures 192 millimeters. The main shaft length is 80 millimeters, while the whole motor is roughly 431 millimeters. Only trained personnel should handle the motor and its installation.
