The Bosch R911285536 (MDD090C-N-040-N2M-110PA2) is a high-performing digital AC servo motor. With a nominal motor speed of 4000 RPM, it can maintain a steady torque value of 10.4 Nm under natural convection and 14.6 Nm with surface cooling, and a continuous current of 24.4 Amps and 34.4 Amps respectively. The maximum torque can reach up to 58.6 Nm, requiring a motor current of 145.7 Amps. With a torque constant of 0.43 Nm/A at 20 degrees Celsius, it offers a winding resistance of 0.29 Ohms and an inductance of 1.6 millihenry. The motor’s thermo-constant is 60 minutes for natural convection and 45 minutes for surface cooling. Weighing approximately 23 kg, it includes an integrated digital encoder for swift feedback. Balanced by standard, the housing can be cooled by multiple methods, and features a power side A connection and a shaft with a DIN 6885-1 keyway. The 11 Nm rated blocking brake operates at 24 Volts DC, consuming 0.5 Amps. It's recommended for installation and operation by certified professionals and comes with a one-year warranty from Indramat USA.
