Product Description

The Bosch MDD112D-L-015-N2L-130PB3 is a MDD series digital AC servo motor. The motor is designed for surface cooling. This cooling method is appropriate for motors that operate at higher loads and consequently have a larger power connector. The rated speed of the motor is 1500 RPM. The MDD112D-L-015-N2L-130PB3 motor supports digital servo feedback. The main shaft features a keyway for balancing as per DIN 6885-1. The power connector is located on side B of the motor housing. The MDD112D-L-015-N2L-130PB3 includes an integrated 60 Nm holding brake. This brake clamps down on the motor shaft to prevent it from moving. The brake releases the motor shaft when a 24 Volts DC release signal is applied. The mass of the holding brake is 3.5 kilograms. The continuous motor torque at standstill is 57 Nm.

The continuous motor current at standstill is 44.5 Amps. The MDD112D-L-015-N2L-130PB3 motor can produce a theoretical maximum torque of 132.4 Nm. The peak current that the motor can produce is 110.5 Amps. The rotor moment of inertia is 0.0230 kg m². The torque constant at 20 degrees Celsius is 1.28 Nm/A. The resistance of the motor windings is 0.39 Ohms at 20 degrees Celsius. The inductance of the windings on the MDD112D-L-015-N2L-130PB3 motor is 5.9 millihenry. The thermal time constant is 90 minutes. The MDD112D-L-015-N2L-130PB3 motor weighs approximately 59 kilograms. Bosch has designed the MDD112D-L-015-N2L-130PB3 motor for 0 to 45 degrees Celsius ambient temperature. The ambient temperature range for motor storage and transportation is -20 to 80 degrees Celsius. The maximum installation elevation should not exceed 1000 meters, otherwise the motor output will derate. The protection category of the motor housing is IP65.
