Product Description
The MDD112D-N-020-N2L-180PB0 is a MDD servo motor from Bosch Rexroth. Its nominal speed rating is 2000 RPM. Approximate shipping weight of the motor is 59 kilograms. Optimal motor operation requires 0 to 45 degrees Celsius ambient temperature and 0 to 1000 meters site elevation. Output for MDD motors derates between 45 and 55 degrees Celsius. Bosch does not permit MDD motor use above 55 degrees Celsius. Output for MDD motors also derates between 1000 and 5000 meters. Bosch does not permit MDD motor use above 5000-meter elevations. If higher ambient temperatures and higher installation elevations occur simultaneously, the respective load factors multiply. MDD motors are protected by their housing and covers which in construction and design adhere to the guidelines found in DIN 40050 and protect against contact to high voltage with motor parts, penetration by extrinsic objects and water penetration.
The housing of the MDD112D-N-020-N2L-180PB0 has a standard design. The motor supports convection cooling out of the box. Surface cooling requires an optional blower. The continuous output torque is 38 Nm with convection cooling and 57 Nm with surface cooling. The continuous output current is 43.8 Amps with convection cooling and 65.8 Amps with surface cooling. An integrated encoder enables digital servo feedback. Motor feedback allows accurate motor control and use for high-precision industrial and commercial applications. The MDD112D-N-020-N2L-180PB0 motor has a shaft with keyway. The motor shaft complies with DIN 6885-1. The motor centering diameter is 180 millimeters and the motor length is 537 millimeters. Diameter of the main output shaft is 32 millimeters. The main power socket is located on side B of the housing. The MDD112D-N-020-N2L-180PB0 does not feature an optional blocking brake.
