R911247267
The R911247267 (MDD065A-N-040-N2L-095GA0), manufactured by Bosch Rexroth Indramat, is a digital AC servo motor highly suited for usage in nibbling, punching and pressing machines and tool changing devices due to its rotor shaft, stator with winding, core with permanent magnets, and an encoder. While an optional blocking brake is not included, it can be purchased separately. The power supply is connected via a power socket on side A of the housing. Both ends of the motor shaft are standard, with motors having a keyway shaft available for order. The motor housing boasts an IP65 protection rating.
Operating at a nominal speed of 4000 RPM, the motor delivers a continuous standstill torque and current of 0.8 Nm and 1.8 Amps respectively, peaking at 2.3 Nm and 8.1 Amps. The rotor inertia is 0.00014 kg m2. At 20 degrees Celsius, the torque constant is 0.44 Nm/A, with a winding resistance of 16 Ohms and inductance of 20.3 millihenry. The thermal time constant for the motor stands at 30 minutes. Weighing roughly 3.2 kilograms and operable in ambient temperatures from 0 to 45 degrees Celsius, the motor’s housing allows for natural convection or surface cooling, with a centering diameter of 95 millimeters, and comes in black.
