Product Description
The Bosch MDD115D-N-020-N2L-130GB2 is a MDD series digital AC servo motor. Because of high power density, the MDD115 motors are well suited to dynamic applications such as punching / nibbing machines, roller feeds and tool changing devices. MDD115 motors are available in torque ratings ranging from 28 to 57 Nm and motor speeds ranging from 1500 to 3000 RPM. As per the type code, the frame size for the MDD115D-N-020-N2L-130GB2 motor is 115 and the frame length is D. The motor features a standard design that cools via natural convection / surface cooling. The nominal speed of the MDD115D-N-020-N2L-130GB2 motor is 2000 RPM. The continuous torque at standstill is 57 Nm and the continuous current at standstill is 77 Amps. The maximum theoretical torque that the motor can deliver is 177.2 Nm. The moment of inertia of the rotor on the motor is 0.00271 kg m2.
The torque constant at 20 degrees Celsius is 0.74 Nm/A and the winding resistance at 20 degrees Celsius is 0.06 Ohms. The inductance of the winding on the MDD115D-N-020-N2L-130GB2 motor is 1 millihenry. The motor thermal time constant is 90 minutes. Shipping weight of the motor is approximately 60 kilograms. A blocking brake with 60 Nm holding torque is available on the motor. The weight of the motor blocking brake is 3.5 kilograms, the voltage rating is 24 volts DC and brake nominal current is 1.5 Amps. The clamping delay and the release delay for the blocking brake are 30 milliseconds and 150 milliseconds respectively. Other motor features include a plain shaft, digital servo feedback, and power connection toward side B. The MDD115D-N-020-N2L-130GB2 motor has a 130-millimeter centering diameter.
