Product Description:

The synchronous motor MDD071A-N-040-N2S-095PA1 is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is a motor for digital drive controllers that converts electrical power from the drive into mechanical rotation for axes that need coordinated positioning and speed control in automated machinery. The factory-installed blocking brake helps prevent back-driving when power is removed, which is useful on vertical axes, and the built-in shaft seal lets the unit operate where oil mist or fine dust may be present.

The motor delivers a continuous standstill torque of 2.2 Nm, allowing stable holding force without overheating during static load conditions. Its nominal speed is 4000 rpm, supporting fast index moves on compact equipment. A centering diameter of 95 mm aligns the stator precisely on the mounting surface to help control runout and vibration. Cables exit on Side A, so power and feedback conductors can be routed toward the drive cabinet without sharp bends. Standard dynamic balancing minimizes residual vibration, and the housing is a standard closed variant that does not require supplemental cooling hardware. The length code A identifies the shortest stator in the 071 frame family, and the single-ended shaft leaves the back face clear for tight installations.

During power-off events, the integrated brake supplies 3.0 Nm of holding torque to maintain axis position. Position data is returned through digital servo feedback, enabling the drive to correct motion within each control cycle. The output shaft uses a keyway profile for direct coupling to timing pulleys or gearboxes. The electrical interface uses a keyed connector, which keeps the plug aligned correctly at the motor housing. The frame size code 071 corresponds to the stator diameter used for this housing size, which helps keep mechanical clearances consistent in compact machine layouts.
