Product Description

One of the families of AC servo motors used to create rapid-response automation systems with drive controllers from Indramat is the MDD family. These synchronous servo motors with high operational reliability are typically used in robotics, machine tools, handling equipment, textile machines, printing and paper processing machines, and transfer facilities.

The MDD112A-N-030-N2M-130PB1 is a servo motor in the Bosch Rexroth MDD series with a frame size of 112 and a frame length of A. It has thermal sensors in its winding to prevent damage due to thermal overload. Its high overload capability also helps prevent such damage as the heat generated during the motor’s operation is effectively eliminated from its windings to the outside wall of its housing. The designated cooling method of this servo motor is surface cooling and natural convection. Its nominal speed is 3,000 revolutions per minute, while the moment of inertia of its rotor is 61 x 10^-4 kgm². This rotor is made from permanent magnet materials composed of iron oxide, giving it low inertia.

Position detection in the MDD112A-N-030-N2M-130PB1 is achieved using digital servo feedback with an integrated multiturn encoder. This encoder evaluates the motor’s absolute indirect position and preserves this information even after a voltage switch-off. Its system accuracy is ±0.5 angular minutes, and its position detection range is 4,096 motor revolutions. It also features a data memory where relevant information like the motor type name and control loop parameters are filed. This promotes the rapid startup of the motor and its risk-free adaptation to its drive controller. The output shaft of this MDD model is one with a keyway per DIN 6885-1 to ensure form-fitting torque transmission.
