Product Description:

The MDD090A-N-020-N2L-110GA2 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is used with digital drive controllers and converts commanded current into regulated torque and speed for accurate motion in packaging lines, printing systems, transfer units, and other automated machinery. Its operating role is to serve as the rotary drive element in axes that must move predictably under changing load conditions. The motor uses the standard housing format of the series, which helps it fit machines built around the MDD platform while keeping the mechanical interface consistent across similar axes.

The electrical ratings include a nominal speed of 2000 rpm and a continuous standstill torque of 3.7 Nm, giving the axis stable running speed and dependable holding capability during low-speed positioning. A built-in blocking brake can provide up to 11.0 Nm of static torque, so vertical or suspended loads can remain secure when drive power is removed. Rotor position is reported through digital servo feedback (DSF), allowing the controller to correct current quickly during acceleration, deceleration, and steady-state motion. Power and feedback cables leave on side A, which can simplify routing when several motors are mounted along the same machine face.

A centering shoulder of 110 mm aligns the flange with gearboxes or direct-mounted loads for accurate concentric positioning. The output uses a plain shaft with a shaft seal, which provides a smooth coupling surface while helping limit lubricant migration and contaminant entry at the shaft passage. A keyed circular connector carries the phase, brake, and feedback contacts, so the motor can be connected without individual lug terminations. The frame code 090 places the unit in the 090 housing size, and standard balancing helps maintain smooth rotation during repeated duty cycles.
