Product Description:

The MDD090B-N-040-N2M-130PR2 synchronous motor is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts commanded current into precise rotary motion for indexing tables, gantry axes, and material-handling equipment. Its multiturn absolute encoder supplies position data over the full rotation range, and the internal blocking brake secures the shaft when power is removed. Standard balancing and a standard housing configuration allow the motor to fit typical industrial mounting arrangements without special mechanical changes.

For continuous duty, the motor delivers 7.2 Nm of standstill torque, maintaining holding force without overheating. Under rated electrical frequency, it reaches a nominal speed of 4000 rpm, supporting applications that require short cycle times and fast axis response. Accurate flange seating is supported by a centering diameter of 130 mm. All power and feedback conductors exit on the right side, and a coded connector interface helps keep cable routing orderly. The 090 frame with length code B keeps the motor compact while preserving enough surface area for convection cooling during extended operation.

The holding brake is rated at 11.0 Nm, helping prevent axis drift when external loads exceed the continuous motor torque. Position feedback to the controller uses digital servo feedback, so absolute position is available immediately after power-up. Torque is transmitted through a splined shaft with a keyway, and sealing integrity is maintained with a shaft seal that helps block lubricant migration toward the stator windings. The motor uses a single drive-side shaft end, and the rotor balance remains in the standard configuration for normal industrial motion duty.
