Product Description
The Bosch MDD115D-N-020-N2M-130GB1 is a versatile servo motor. It belongs to the MDD product line. Operators can select from motors with a wide range of built-in and optional features. Built-in features of MDD motors include IP65 protection, sealed cable connectors, maintenance-free operation, and support for digital servo feedback. Operators can select one of two types of motor shafts, three cooling methods, and the power socket location. Operators can order an optional blocking brake for their MDD motor. The MDD115D-N-020-N2M-130GB1 motor has a plain shaft with a shaft seal. An integrated multiturn encoder enables servo feedback. The optional blocking brake on the motor is rated for 45 Nm holding torque. The brake operates according to the electrical release principle. Its voltage rating is 24 Volts DC and its current raw is 1 Amp.
Moment of inertia of the blocking brake is 0.00095 kg m2. The brake’s release delay is 55 milliseconds and its clamping delay is 18 milliseconds. Mass of the blocking brake is 1.9 kilograms. Mass of the servo motor is 60 kilograms. Its nominal speed rating is 2000 RPM. The continuous torque at standstill is 57 Nm with convection cooling and 76.2 Nm with surface cooling. The continuous current at standstill is 77 Amps with convection cooling and 102.9 Amps with surface cooling. The thermal time constant is 90 minutes with convection cooling and 60 minutes with surface cooling. The MDD115D-N-020-N2M-130GB1 motor’s standard housing is designed for surface cooing and convection cooling. The power connection is on side B of the standard motor housing. Only approved accessories should be used with the servo motor. only qualified personnel should install and operate the servo motor.
