Product Description
Servo motors in the MDD series by Bosch Rexroth guarantee high contouring accuracies at high feed rates, especially when used for cutting in high speed ranges. They can be used for application-specific applications, covering areas such as food processing and packaging, and machine tools.
The MDD093C-N-040-N2L-110GB0 is a MDD servo motor model with an inbuilt thermal sensor to protect it from irreversible damage by thermal overload. Its nominal speed is 4,000 revolutions per minute, and it belongs to Balance Class R according to DIN VDE 0530. With its brushless design and lifetime-lubricated bearings, the servo motor supports maintenance-free operation. It also supports cooling by natural convection and surface cooling, allowing it to accommodate extreme loads. The motor’s high overload capability is due to the efficient removal of heat from its stator windings to the outside walls of its housing. This housing has an IP 65 Ingress Protection rating per EN 60529, since it is safe from the penetration of solid external materials and water jet sprays.
Another feature of the MDD093C-N-040-N2L-110GB0 is its compact build, which gives it a high power-to-weight ratio. Its output shaft is a plain type that ensures a backlash-free and non-positive transmission of torque. The shaft has a shaft sealing ring that prevents fluid from entering the machine to damage it. Thanks to the digital servo feedback of this MDD model, its position can be determined precisely. This encoder’s system accuracy is ±0.5 angular minutes, and its measurement method is optical. Electronic commutation in the motor gives it a high cyclic load capacity that permits continuous start-stop operations with high repetition rates. Its rotor’s moment of inertia is 42 x 10-4 kgm2.
