Product Description:

The MDD090B-N-030-N2L-130PL2 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is a permanent-magnet AC unit intended to drive automated axes that require fast acceleration, repeatable speed, and accurate positioning. When paired with a digital drive controller, the motor converts regulated three-phase current into controlled torque for machine tools, transfer stations, and handling modules in industrial automation.

During continuous operation, it generates 7.2 Nm of standstill torque and reaches a rated speed of 3000 rpm under nominal voltage and load. A blocking brake integrated at the non-drive end applies 11.0 Nm to lock the shaft when power is removed, helping prevent drift on vertical or suspended loads. Rotor position is relayed through digital servo feedback (DSF), enabling the controller to adjust current vectors with high bandwidth. The flange centers on a 130 mm pilot diameter for precise concentric mounting, while power and feedback lines enter from the left through a connector that allows quick connection without rewiring. The rotor is balanced to the standard grade to limit vibration, and the standard housing dissipates heat by natural convection.

Mechanical transmission is handled by a keyway on the shaft, allowing positive engagement with pulleys or couplings. A protective shaft seal surrounds the journal to help keep dust and coolant away from internal bearing areas. Classified as a motor for digital drive controllers, it uses size 090 laminations and length code B while supplying the stated torque in a compact housing. The left-side connection direction simplifies layouts where cable trays run parallel to the motor flank, and the single shaft end without a side B extension reduces overhung moments on the bearing set.
