Product Description:
The MDD071B-N-040-N2M-095GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where regulated inverter current is converted into controlled rotary motion for positioning tables, pick-and-place heads, and other automated machine axes. Its integrated feedback and compact mechanical layout let the motor fit directly into closed-loop motion systems used in packaging, printing, and material-handling equipment. This arrangement allows the drive to track command changes quickly during acceleration, positioning, and steady-speed operation.
At standstill, the motor sustains 4.4 Nm of continuous torque, allowing it to support static loads without excessive heating. During motion, it reaches a nominal speed of 4000 rpm, which suits fast feed axes and general servo tasks. Mounting accuracy is supported by a 95 mm centering diameter that helps align the flange with the machine frame. Position data come from an integrated multi-turn absolute encoder, so the controller can retain shaft position information after power is removed. Mechanical power is transmitted through a plain shaft without keyways, which is suited to clamp-style couplings and supports a straightforward shaft-to-hub connection. A standard ribbed housing helps dissipate heat during continuous operation, and the drive-side shaft arrangement keeps the mechanical package compact.
Service connections are routed on side B, where a sealed connector carries both power and feedback lines to reduce external wiring points. Feedback is returned through digital servo feedback, giving the drive position and velocity data for closed-loop control. A blocking brake rated at 3.0 Nm engages automatically when the inverter is disabled, which helps hold the axis at rest on vertical or gravity-affected loads. A shaft seal helps keep coolant and debris away from internal components, and the standard housing finish supports use in enclosure-mounted industrial installations. This layout also helps keep cable routing orderly when the motor is installed close to surrounding machine structures.
