Product Description:

The MDD090B-N-020-N2L-130GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is engineered to operate with digital drive controllers, providing closed-loop speed and position control for axes in automated assembly lines, material-handling equipment, and CNC machinery. By translating drive commands into precise rotary motion, the unit helps keep cycle times consistent and repeatable in industrial automation. Its synchronous design also supports stable motion during frequent starts, stops, and direction changes on positioning axes. This supports indexing, contouring, and point-to-point moves that rely on repeatable motor response.

Mechanical alignment is handled by a centering diameter of 130 mm, allowing the housing to seat accurately against mating flanges. Cabling enters on side A, and the power and feedback lines terminate through a single connector, which keeps the electrical interface compact. The consolidated cable entry also reduces the amount of free space needed around the connection area. Under continuous stall conditions, the motor develops 7.2 Nm of torque, so axis loads can be matched to the motor during low-speed indexing or holding tasks. During motion, the shaft reaches a nominal speed of 2000 rpm, providing a consistent operating point for speed-controlled applications while remaining within the motor's thermal limits. Standard dynamic balancing is applied to the rotor to help reduce vibration during operation.

For position security when power is removed, an integrated blocking brake supplies 11.0 Nm of holding torque to resist back-driving on vertical or overhung loads. Real-time rotor feedback is delivered through digital servo feedback, enabling high-resolution commutation and closed-loop control without an external encoder. The brake and feedback combination helps the axis remain controlled during powered motion and at standstill. The output interface uses a plain shaft, and the front bearing region is equipped with a shaft seal to help limit contaminant entry. This shaft arrangement allows couplings or pulleys to clamp directly to the shaft surface while protecting the bearing area during normal machine operation.
