MDD041A-N-100-N2K-050MB0
Bosch Rexroth Indramat manufactures the MDD041A-N-100-N2K-050MB0 in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical command signals into rapid, precise shaft rotation needed for coordinated motion sequences on automated machinery. The design fits tight mounting envelopes while still supporting the high cycle rates demanded by servo axes on assembly stations and other compact automation equipment. This makes it suitable for positioning tasks that require quick speed changes and repeatable motion over short cycle times.
The motor reaches a nominal speed of 10000 rpm, allowing direct coupling to spindles or gear stages that must follow rapid command updates. At standstill, it can deliver 0.64 Nm, which provides holding torque during positioning. Accurate alignment is supported by a mounting flange with a 50 mm centering diameter. Power and feedback leads exit on side B, helping keep cables clear of the shaft side in narrow installations. Torque is transmitted through a shaft with a keyway, and the motor uses a standard shaft end on the drive side only. Additional physical details include standard dynamic balancing, a standard housing, motor size 041, motor length code A, and a single electrical interface.
Control feedback is provided through resolver feedback, and the rotor also uses an integrated absolute encoder for position initialization at power-up. Motor-side wiring is made through a sealed connector, so no terminal box is required and the connection point remains compact. The assembly is produced without a shaft seal, which suits dry cabinet operation where drive-train protection is handled externally. Because the unit has no shaft seal, it is best suited to clean, dry mounting areas rather than contaminated spaces. The unit is delivered without a blocking brake, so any vertical or suspended load must be held by the drive or an external locking mechanism.
