Product Description:

Bosch Rexroth Indramat manufactured the Servo Motor type MD112C-N-030-N2L-130PA0 which is specialized for functions in Industrial automation. In standard mode, this servo motor produces 28.0 Nm continuous torque from zero speed. Surface cooling technology enables the torque to rise to 44.0 Nm with high efficiency.

The MD112C-N-030-N2L-130PA0 servo motor consumes 43.4 amperes at a standstill. Surface cooling enables the motor to maintain exactly 68.1 A as its current value. The maximum torque capacity of this motor reaches 100.4 Nm based on theoretical conditions. This motor product line fulfills requirements that require extensive torque capabilities across different speed ranges. The rotor moment of inertia has been determined at 170 × 10⁻⁴ kgm². The 20°C temperature conditions yield a torque constant value of 0.65 Nm/A for the MD112C-N-030-N2L-130PA0 servo motor. Proper torque delivery operates consistently due to the accuracy of these capabilities. At 20°C temperature, the winding resistance measures 0.14 ohms. Tests confirm the motor has a winding inductance value of 2.0 mH. Standard mode operation enables the thermal time constant to reach 100 minutes. The application of surface cooling shortens the thermal time constant to 75 minutes. The total weight of the motor equipment amounts to 48 kilograms.

The Servo motor MD112C-N-030-N2L-130PA0 exists with insulation class F. The material serves as thermal insulating protection to enable both safety and steady thermal operation. The system has IP65 protection status according to specifications which safeguards the product from dust infiltration and weak water pressure exposure. The motor operates at a speed of 3000 min⁻¹. The allowed operating environment temperature exists between 0 degrees Celsius and +45 degrees Celsius. The product demands that storage occur within the temperature range of –20°C up to +80°C.
