Product Description:
The MDD112D-N-040-N2M-130BG0 is a Digital AC servo motor manufactured by Bosch that is designed for precise motion control in industrial automation. The servo motor is resistant to dust and water ingress and has an IP65 rating; its casing is jet black. Bosch keeps its components at the ideal working temperatures with the help of convection and surface cooling, as well as an insulation class F.
The digital axis servo motor MDD112D-N-040-N2M-130PB2 has a nominal speed of 4000 RPM and can produce a peak torque of 132.2 Nm, backed by a peak current of 329.1 A. At 20°C, the winding resistance is 0.05 Ohms and the torque constant is 0.43 Nm/A. The winding causes a loss of only 0.05 mH. Natural convection has a thermal time constant of 120 minutes and surface cooling of 90 minutes, allowing for consistent thermal control. The built-in multiturn encoder ensures accurate feedback for closed-loop control, which is essential for precision positioning and speed regulation. This encoder is also essential for motor speed regulation.
The MDD112D-N-040-N2M-130BG0 servo motor is equipped with a brake system that provides a blocking torque of 40 Nm. With a nominal current of 1.35 A, the brake performs its function at a voltage of 24 V DC. Both the clamping delay and the brake release delay are measured in milliseconds, with the latter being thirty milliseconds. This allows for dependable holding and release throughout operations. The balance class is standard, and the servo motor’s construction supports both convection and surface cooling for flexible integration. The combination of advanced encoder technology and robust mechanical design makes the MDD112D servo motor suitable for demanding motion control tasks where reliability and accuracy are required.
