Product Description:

The MDD090A-N-020-N2L-130GL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning axes, packaging spindles, and other closed-loop automation tasks. The motor is supplied in the A length code within the 090 frame, and its standard housing and balancing profile suit panel-mounted or machine-integrated installations where moderate inertia and repeatable speed control are required. This makes the unit suitable for servo systems that need accurate acceleration, steady running speed, and controlled positioning during repetitive machine cycles.

A centering diameter of 130 mm provides concentric alignment between the motor flange and the driven assembly. A continuous standstill torque of 3.7 Nm allows the shaft to resist external loads without overheating while the control loops remain active. During motion, the rotor can maintain a rated speed of 2000 rpm, matching common controller output ranges for medium-speed production lines. Position and velocity are reported through Digital servo feedback (DSF), which supports high-resolution commutation and electronic motor data handling inside the drive. All power and feedback conductors exit on the left side, which can simplify cable routing when the motor is mounted on the right wall of a cabinet or gantry arm.

Static holding requirements are covered by an integral blocking brake that produces 6.5 Nm of torque when coil power is removed, helping prevent back-driving on vertical or indexing axes. Electrical terminations use a keyed connector, which helps reduce wiring errors and keeps installation straightforward. The output stage uses a plain shaft finished to ISO tolerances for coupling to the driven machine element. Contamination at the rotor interface is limited by a fitted shaft seal.
