Product Description

MDD090C-N-020-N2L-110PA1 is a servo motor. It is produced by Bosch Rexroth. Permanent magnets used for MDD motors allow construction of motors with low inertia. Electronic commutation used instead of carbon brushes improves reliability, reduced maintenance requirements, and allows operators to install MDD motors where brushed motors can not be installed due to safety issues. Temperature monitoring of the windings helps to prevent overload damage. The IP65 rated housing provides robust environmental protection. MDD motors are protected by housing and covers which adhere to the guidelines found in DIN 40050 and protect against contact to high voltage with motor parts either moving or alive (contact guards), the penetration by extrinsic objects and water penetration. The motor has a shaft with keyway. The shaft complies with DIN 6885-1.

Centering diameter of the motor is 110 millimeters. The main power connection is on side A of the housing. Bosch has designed the MDD090C-N-020-N2L-110PA1 motor for surface cooling and convection cooling. The required ambient temperature is 0 to 45 degrees Celsius. Unused MDD motors must be kept in storage where the temperature is between -20 and 80 degrees Celsius. The MDD090C-N-020-N2L-110PA1 is equipped with a blocking brake. Holding torque of the brake is 6.5 Nm. The voltage rating is 24 Volts DC and the current draw is 0.5 Amps. Release delay of the brake is 60 milliseconds and the clamping delay is 20 milliseconds. Continuous torque at standstill for the motor is 10.4 Nm with convection cooling and 16 Nm with surface cooling. Continuous current at standstill is 12.1 Amps with convection cooling and 18.5 Amps with surface cooling. Weight of the AC servo motor is 23 kilograms.
