MDD071B-N-060-N2T-095GR0
Bosch Rexroth Indramat manufactured the MDD071B-N-060-N2T-095GR0 as a member of the MDD Synchronous Motors series and classifies it as a motor for digital drive controllers. It is installed on servo axes where compact dimensions and rapid acceleration are required to maintain throughput in assembly lines, packaging stations, and handling modules. In these systems, the motor converts drive commands into controlled rotary motion for positioning, indexing, and repeatable speed regulation. The model uses a standard housing and standard dynamic balancing so it can be mounted directly to machine frames without custom vibration isolation. Electrical power and feedback lines are routed through a sealed connector to simplify wiring and help maintain a compact installation envelope.
The motor delivers a continuous standstill torque of 4.4 Nm, enough to hold loads when the axis is energized but motionless. During operation, it can reach a nominal speed of 6000 rpm, allowing direct drive of high-speed tooling without gearing. A centering pilot of 95 mm keeps the stator concentric and minimizes runout. All power and sensor connections emerge on the right side, so cabinet layouts can use a fixed cable bend radius. Position data is supplied by a multi-turn absolute encoder, which maintains the shaft angle across power cycles and removes the need for homing routines. The length code B frame preserves moderate inertia for responsive acceleration while keeping the motor compact enough for tightly spaced machine assemblies.
Feedback to the drive controller is transmitted as digital servo feedback (DSF) signals, enabling high-resolution commutation with minimal latency. Contaminants are kept away from the precision bearings by a shaft seal, and the plain, single-ended shaft suits applications that do not require a secondary output. The sealed shaft area helps protect internal bearing surfaces during routine operation in enclosed machinery. The compact 071 frame is supplied without a holding brake, so any static locking force must be provided externally or by drive torque. Heat is dissipated through natural convection, and the keyed connector allows tool-free exchange of premade cables.
