MDD071A-N-040-N2S-095PA1
The MDD071A-N-040-N2S-095PA1 synchronous servo motor is manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precisely regulated rotary motion for positioning axes and feed drives used in automated machinery. The device belongs to the 071 frame class and uses length code A, which places it in a compact housing for tight installation spaces. Its design suits applications that need accurate motion control without requiring a large motor body.
Mechanical alignment is handled by a centering pilot of 95 mm, which sets the radial reference when the flange mounts against a machine plate. Under continuous duty, the rotor can produce 2.2 Nm of torque at standstill without exceeding thermal limits, while its design supports speeds up to 4000 rpm to suit fast traverse cycles. The stator windings are connected through a keyed connector interface that helps maintain shielding continuity. Motion feedback is delivered through integrated digital servo feedback, allowing the drive to monitor rotor position and close the velocity loop without external sensors. Standard dynamic balancing reduces vibration transfer to adjacent components, and the cast housing helps move heat into the machine structure.
The motor holds position during power-off events with an internal brake that applies 3.0 Nm of static torque. All power and sensor leads exit on Side A, which keeps cable routing on one face of the motor. The output shaft uses a keyway for positive mechanical coupling and includes a shaft seal that helps limit lubricant migration into the encoder chamber. A single-ended shaft layout leaves the rear of the motor closed, which can simplify guarding in compact machine sections. This arrangement also avoids the need for coupling components at a second shaft end.
