Product Description

MDD112D-L-015-N2L-130PA1 is a Bosch Rexroth servo motor. It is part of the MDD series. The motor has a housing with a larger power connector. It is especially designed for high-load applications and its housing is designed for surface cooling. Speed rating of the motor is 1500 RPM. The continuous output torque at standstill is 57 Nm. The continuous output current at standstill is 44.5 Amps. Theoretical maximum torque of the motor is 132.4 Amps. The peak current rating of the servo motor is 110.5 Amps. Moment of inertia of the motor rotor is 0.023 kg m2. Torque constant of the motor is 1.28 Nm/A at 20 degrees Celsius. Resistance of the motor windings is 0.39 Ohms at 20 degrees Celsius. Inductance of the motor windings is 5.9 millihenry.

Thermal time constant for the MDD112D-L-015-N2L-130PA1 motor is 90 minutes. Mass of the motor is 59 kilograms. Its housing has a special centering diameter of 130 millimeters. The motor housing has a flange at one end. This is a flat metal plate with holes for mounting screws. Size of the flange on the motor is 193 millimeters. Length of the motor is 537 millimeters. The power connection is on side A of the housing. The power connector must be ordered separately. The motor supports digital servo feedback. The feedback connector must also be ordered separately. Main shaft on the motor has a plain design. A blocking brake is installed on the MDD112D-L-015-N2L-130PA1 motor. This brake acts as a safety device and allows shaft rotation only after a 24 Volts DC release signal is received. To prevent installation errors, only trained personnel should handle and install the servo motor.
