Product Description

The Bosch Rexroth MDD112B-N-030-N2M-130PA3 is a digital AC servo motor. Together with digital drive controllers, the motor is well-suited to applications such as textiles, packaging machines, printing machines, robotic and tools. MDD112 motors are specially well suited to applications that require high-precision and an extreme degree of synchronism such as grinding machines. The nominal speed of the MDD112B-N-030-N2M-130PA3 motor is 3000 RPM. The continuous torque at standstill is 17.5 Nm and the continuous current at standstill is 28 Amps. The theoretical peak torque for the motor is 64.5 Nm and the peak current is 110 Amps. The moment of inertia of the motor rotor is 0.0012 kg m². Torque constant for the MDD112B-N-030-N2M-130PA3 motor is 0.62 Nm/A at 20 degrees Celsius. The resistance of the motor winding is 0.25 Ohms at 20 degrees Celsius.

The inductance of the windings on the MDD112B-N-030-N2M-130PA3 motor is 3.1 millihenry. The thermal time constant is 90 minutes. The motor includes a blocking brake that is rated for 60 Nm holding torque. The brake is used to prevent shaft rotation at startup. The brake only allows shaft rotation after a 24 Volts DC release signal is applied. The mass of the blocking brake is 3.5 kilograms, the nominal current rating is 135 Amps, the release delay is 150 milliseconds and the clamping delay is 30 milliseconds. Housing of the MDD112B-N-030-N2M-130PA3 is standard and is suited to natural cooling. The motor supports digital servo feedback with integrated multiturn absolute encoder. The motor centering diameter is 130 millimeters. The motor output shaft includes a keyway. The motor power connection is on side A of the housing. The weight of theMDD112B-N-030-N2M-130PA3 motor is 36 kilograms. This product can be shipped globally with a one-year warranty period from Wake Industrial.
