Product Description:

The MDD071B-N-060-N2T-095PB0 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical commands from servo amplifiers into mechanical rotation for positioning axes and feed drives in industrial automation. The model features a standard housing and standard dynamic balancing, making it suitable for general-purpose machine tool and handling systems where compact form and consistent vibration behavior are required. It is commonly used where stable feedback and predictable mechanical behavior are needed for repeated motion cycles.

At standstill, the motor supplies 4.4 Nm of continuous torque, which is the steady load it can support without overheating. During operation, the rotor can reach a nominal speed of 6000 rpm, allowing high-speed cycles when paired with matching drive electronics. A centering diameter of 95 mm simplifies alignment to gearboxes or mounting flanges and helps limit radial offset during installation. Power and feedback conductors exit on Side B through a sealed connector, an arrangement that suits tight cabinet layouts and keeps cable routing to one end of the motor. Position and velocity are reported through digital servo feedback (DSF), enabling closed-loop control with fast response. The motor also uses a type B length code, a keyway shaft for positive torque transfer, and a standard connector interface.

An integrated multiturn absolute encoder tracks shaft revolutions even when power is removed, so the control system can retain position information after a restart. The housing is fitted with a shaft seal, which helps keep contaminants from adjacent mechanics out of the stator cavity. The motor is supplied without a blocking brake, so any holding function at standstill must come from external mechanics or drive-controlled torque. Its compact build uses the 071 frame size, and the standard drive-side shaft end avoids extra protrusion at the nondrive end to save space around nearby machine parts. That arrangement is useful where the motor must fit into closely spaced axis groups or compact feed assemblies.
