Product Description:
The MDD090B-N-030-N2M-130GB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated armature current into controlled mechanical rotation for positioning, feed, and indexing axes in automated production lines. The unit occupies the size-090 frame and includes an integrated multi-turn absolute encoder so motion control loops receive high-resolution position data without external transducers. This arrangement lets the drive monitor rotor position after startup and maintain accurate feedback during normal axis movement.
At standstill, the motor supplies 7.2 Nm of continuous torque, allowing closed-loop control to support loads without thermal overload. Once commutated, it can accelerate to a nominal speed of 3000 rpm, which suits the operating range of common Rexroth drive modules. Standard balancing reduces residual vibration, and a centering shoulder of 130 mm positions the flange precisely on mounting plates. Command and actual values are exchanged through digital servo feedback (DSF) generated by the integrated encoder, giving the controller immediate velocity and position information. For gravity-loaded axes, a blocking brake delivers 11.0 Nm of static holding torque so the shaft remains fixed during power loss or emergency stop events.
All conductors exit through the connection on side B, and the sealed connector permits quick replacement without rewiring. A shaft seal protects the bearing set from coolant or oil, while the drive side uses a plain shaft that couples with keyed or clamping hubs as required. The mechanical interface follows the standard shaft-end layout without an additional output on the opposite side. A standard cast-aluminum housing encloses the stator, and motor length code B gives an intermediate stack depth that keeps the overall package moderate for this frame size. With the cables grouped on one side, surrounding guards and machine plates can remain clear of the connector area.
