MDD090A-N-020-N2M-110GB1

Product Description

The MDD090A-N-020-N2M-110GB1 is a 2000 RPM rated servo motor from Bosch Rexroth. It is a MDD series motor with 275 millimeters housing length and 140 millimeters flange size. Each mounting hole on the flange has an 11 millimeter diameter. The motor has a plain shaft with 24 millimeter diameter. Length of the shaft available outside the housing is 50 millimeters. The motor gets electrical power from a servo controller. The motor power connector depends on the motor and must be ordered separately. The location for the power connector on the MDD090A-N-020-N2M-110GB1 motor is on side B of the housing. Operators can order a straight or angle connector for the feedback cable. The feedback connector must also be ordered separately. The MDD090A-N-020-N2M-110GB1 supports digital servo feedback with integrated multiturn absolute encoder. Multiturn encoders provide feedback after multiple shaft revolutions.

The standard motor housing is suited to natural convection and surface cooling. With natural convection the continuous torque at standstill is 3.7 Nm. With natural convection the continuous current at standstill is 4 Amps. With surface cooling the continuous torque at standstill is 5 Nm. With surface cooling the continuous current at standstill is 5.4 Amps. With natural convection the thermal time constant is 45 minutes. With surface cooling the thermal time constant is 30 minutes. Mass of the servo motor is 12.5 kilograms. The motor has a 6.5 Nm rated blocking brake. The brake operates i.e. releases the shaft after application of a 24 Volts DC signal. Mass of the motor blocking brake is 0.5 kilograms. To prevent installation errors and other installation-related problems, only trained personnel should handle the servo motor and associated equipment and accessories.
