The Rexroth R911290956 (MHD093C-058-NP1-AA) is a MHD093C digital servo motor with a 058 winding code. It boasts a length type 'C' and a motor size of 093. Its construction includes a digital servo feedback encoder delivering signals to the drive controller and a 22Nm holding brake. With a key per DIN6885-1, the shaft has a sealing ring. The design encompasses natural convection or surface cooling housing and an A side connector. It offers four types of cooling and motor overtemperature ranging from Natural 60K to Liquid 60K/100 with variable continuous torque and current. The R911290956 (MHD093C-058-NP1-AA) operates optimally at a peak current of 127.4A and runs at a motor speed of 4000min⁻¹. It demonstrates four pole pairs, a winding resistance of 0.32Ω, and a winding inductivity of 2.6mH. Rated performance, frequency, and voltage vary based on cooling type. Other features include a moment of inertia of the rotor at 3.0x10⁻⁴, a theoretical maximum torque of 88Nm, a maximum speed of 6000min⁻¹, and a motor mass of 23.5kg. Operating conditions require an environment 1000m above MSL and between 0-40°C. The R911290956 (MHD093C-058-NP1-AA) is IP65 protected, insulated per F class, and includes a one-year international warranty from Indramat USA.
