Product Description

The Bosch Rexroth MDD112D-N-020-N2M-180PB0 is an advanced servo motor. The motor is without a blocking brake. Bosch does provide blocking brakes for MDD112 series motors with holding torque ratings of 14 / 40 / 60 Nm. Depending on requirement, the brakes can be specified at the time of equipment ordering. The ambient conditions that are specified for motor operation by Bosch include 0 to 45 degrees Celsius ambient temperature and altitude of up to 1000 meters. During storage the MDD112D-N-020-N2M-180PB0 can be kept in environments where the temperature is between -20 and 80 degrees Celsius. Protection category of the MDD112D-N-020-N2M-180PB0 is IP65. The housing coat is RAL 9005 (prime black coat). The insulation class of the MDD112D-N-020-N2M-180PB0 motor is F. The nominal motor speed is 2000 RPM.

The usable motor speed is determined by the torque requirements of the application. The usable speed found in the selection lists of the motor-drive combinations is binding for standard applications. The usable speed for other applications can be found using the required torque in the torque-speed characteristic curves. The continuous torque and current at standstill are 38 Nm and 43.8 Amps. The peak torque and current are 134.8 Nm and 166.4 Amps. The rotor moment of inertia is 0.023 kg m². The shaft on the motor includes a keyway. Mass of the MDD112D-N-020-N2M-180PB0 motor is 59 kilograms. The MDD112D-N-020-N2M-180PB0 is designed for cooling via natural convection or surface cooling. The motor supports digital servo feedback with integrated multiturn absolute encoder. Centering diameter of the MDD112D-N-020-N2M- 180PB0 is 180 millimeters. The power connector is on the right side of the housing. The motor must be installed by qualified personnel.
