Product Description:
The MDD071B-N-030-N2S-095GB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it converts regulated electrical energy into precise rotary motion for positioning tables, pick-and-place heads, and feed axes in automated machinery. This type of motor is commonly used where fast starts, short settling times, and repeatable positioning are required across frequent production cycles. The model uses a plain shaft for direct coupling, and an integrated blocking brake helps hold vertical or suspended loads when drive power is removed.
A centering shoulder of 95 mm aligns the housing accurately on the machine frame, which helps keep the shaft axis true during installation and coupling. Power and feedback cables exit toward Side B, and the single-piece Connector interface keeps the connection point compact and easy to route in enclosed machine spaces. This arrangement can reduce cable bend stress near the motor and leave more free space around nearby guards or tooling. When held statically, the motor can provide 4.4 Nm of continuous stall torque, and rated operation reaches 3000 rpm under normal speed control. The 071 frame and B-length stator support this operating range, and the standard housing dissipates losses by natural convection.
The blocking brake provides 3.0 Nm of holding torque for idle retention or controlled stopping when the axis is not actively driven. Position data are transmitted through digital servo feedback (DSF), allowing the connected drive to monitor rotor movement and maintain closed-loop accuracy throughout motion profiles. This feedback path lets the drive correct speed and position errors as load conditions change during operation. A factory-installed shaft seal helps prevent lubricant escape and reduces the entry of coolant spray or dust in typical industrial enclosures. The rotor uses standard balancing, which supports smooth running with rigid couplings and helps limit vibration during repeated acceleration and deceleration.
