Product Description

Several features distinguish Bosch Rexroth’s high-efficiency MDD motors, including their compact size and high power density. They also provide high contouring accuracies at high feed rates, especially when used for cutting in high speed ranges. Their applications include machine tools, textile machines, and robotics.

The MDD115C-N-030-N2M-130PB0 is a maintenance-free synchronous servo motor of the MDD series with a brushless design and lifetime-lubricated bearings. Its bearings support high radial loads, promoting simple installation since pinions and belt pulleys are directly attached to the shaft. The servo motor features a standard housing design that is suited for cooling by natural convection and surface cooling. It has a high overload capability because heat is efficiently eliminated from its stator windings to the external walls of its housing. This model also displays improved operational reliability because its housing is completely sealed and impervious to solid extrinsic materials and multidirectional water jet sprays. Hence, its Ingress Protection rating is IP 65 according to EN 60529.

Accurate position detection in the MDD115C-N-030-N2M-130PB0 is via its integrated encoder system. This model uses digital servo feedback with an integrated multiturn absolute encoder. The encoder’s system accuracy is ±0.5 angular minutes, while its measurement method is optical. Its data memory stores information like the motor type name and control loop parameters, improving its startup time and promoting its safe adaptation to the drive controller. Since its permanent magnet is composed of rare earth and iron oxide, it has low inertia and a favorable torque-inertia ratio for high dynamics. The motor’s nominal speed is 3,000 revolutions per minute, while its theoretical maximum torque is 146.2Nm. Its rotor’s moment of inertia is 222 x 10^-4 kgm².
