The Bosch R911279424 (MHD112C-058-PP3-AN) is a synchronous motor from the MHD Series, complete with a built-in holding brake. This motor falls into the 112 frame size category, with a frame length labelled as C, and a winding code of 058. Features include a centering diameter of 130mm, flange size of 192mm and a motor housing length of 458mm. The shaft comprises a sealing ring, key, and a diameter of 32mm. The power connector is located on side A and its output direction must be selected when ordered. The motor's holding brake specifications include a hold torque of 70 Nm, rated voltage of 24V, rated current of 1.29 Amps, connection time of 53ms, and disconnection time of 97ms. The motor has a weight of 45 kg, while the brake weighs 3.8kg, culminating in a total weight of 48.8kg. Other key details include a peak current of 239 Amps, a torque constant of 0.8 Nm/A at 20 °C, a voltage constant of 72.7 volts per 1000 RPM at 20 °C, and a winding resistance of 0.12 Ohm at 20 °C. With four pole pairs, the R911279424 (MHD112C-058-PP3-AN) can support digital servo feedback through its integrated multiturn absolute encoder. Able to be naturally convection-cooled or surface-cooled, its performance varies depending on the cooling technique and other operating variables. With an overtemperature of 60K, the natural convection cooling results in a rated speed of 2000 RPM, rated torque of 15.3 Nm, rated current output of 15.2 Amps, and a rated voltage of 148 Volts.
