MDD090A-N-030-N2M-110GA2

Product Description

The Bosch MDD090A-N-030-N2M-110GA2 is a MDD series servo motor. The term “servo” in the motor name signifies that the motor supports feedback and can be used with a servo drive controller. The feedback feature is enabled by an integrated encoder. The encoder is a sensor that measures motor parameters such as speed and torque. The feedback from the motor is transmitted to the controller via dedicated feedback cable. The motor power is also supplied by the controller and reaches the motor through a dedicated power cable. This power cable terminates on a connector that, in the case of the MDD090A-N-030-N2M-110GA2 motor, is located on side A of the motor housing. Bosch has provided motor technical data for natural convection and for surface cooling. With natural convection, the continuous torque and current at standstill are 3.7 Nm and 6.3 Amps respectively.

With surface cooling, the continuous torque and current at standstill are 5 Nm and 8.5 Amps respectively. The thermal time constant for the MDD090A-N-030-N2M-110GA2 with natural convection is 45 minutes. The thermal time constant for the motor with surface cooling is 30 minutes. The MDD090A-N-030-N2M-110GA2 motor has a 14-kilogram mass. The nominal motor speed is 3000 RPM. The motor housing has a 110 millimeter centering diameter. The output shaft on the MDD090A-N-030-N2M-110GA2 motor is plain. The MDD090A-N-030-N2M-110GA2 includes a blocking brake. The technical data for the brake include 11 Nm holding torque, 0.5 Amps nominal current, 60 milliseconds release delay and 20 milliseconds clamping delay. The brake mass is 0.5 kilograms. The brake is designed to release the motor shaft after the application of a 24 Volts DC signal. The brake prevent shaft rotation until this signal is applied.
