Product Description:

Bosch Rexroth Indramat's MDD071B-N-040-N2L-095PA0 is a synchronous motor for digital drive controllers in the MDD Synchronous Motors series. Within an automation cell, the unit couples to a drive inverter and translates commanded current into precise rotary motion for pick-and-place axes, small gantries, and packaging spindles that depend on accurate response to changing load conditions. This design supports repeatable speed regulation and closed-loop positioning in compact machinery, and its standard housing allows straightforward integration where consistent servo response is required.

The centering flange secures the stator in a bore with a 95 mm register, and all electrical leads exit on Side A through a plug-in connector so wiring remains straightforward. At standstill, the motor can deliver 4.4 Nm of continuous torque, which helps the axis maintain load torque without overheating. Standard balancing keeps vibration low over the service range, and the unit is supplied without a blocking brake, so any required holding force must come from an external clamp or maintained drive current. Position data is returned through digital servo feedback, giving the controller rotor position information for commutation and diagnostic functions.

During dynamic operation, the rotor reaches a nominal speed of 4000 rpm, allowing fast indexing while staying within the thermal range associated with motor length code B. The 071 frame size places the motor in a medium-power housing class, and the shaft uses a ground keyway for positive torque transmission to pulleys or couplings. The output is protected with a shaft seal that helps limit the ingress of lubricants, coolants, and fine particulates. A standard shaft end is provided only on the drive side, leaving Side B closed and helping the motor fit into compact mounting spaces where rear clearance is limited.
