Product Description:

The MDD090B-N-020-N2L-130PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for digital drive controllers, it supplies controlled rotary motion in automated machinery that requires precise positioning and repeatable speed profiles. An integral blocking brake helps secure vertical or suspended loads when power is removed, and the standard housing with balanced running supports direct installation on machine frames. This arrangement makes the motor suitable for axes that need accurate starts, stops, and holding behavior during normal machine operation.

The centering pilot on the flange measures 130 mm, which provides accurate alignment between the motor and the coupled machine. At standstill, it can continuously deliver 7.2 Nm of torque, allowing the motor to maintain controlled force without overheating the windings. During operation, the rotor reaches a nominal speed of 2000 rpm, which suits moderate-speed packaging and transfer axes. Power and feedback conductors exit on Side A, which can simplify cable routing when the drive is mounted on the same side of the machine. Positional data is returned through digital servo feedback, giving the controller real-time rotor angle information for accurate velocity and position control.

The blocking brake can hold up to 11.0 Nm, so gravity-loaded Z-axes can remain stationary when the inverter is disabled. Instead of a splined output, the shaft uses a machined keyway that fits common hub connections. The motor has size code 090, which places it within the corresponding frame dimensions of the series. A fitted shaft seal helps keep dust away from the bearing area and reduces lubricant migration along the shaft. The motor also uses standard dynamic balancing, motor length code B, and a plug-style connector interface for straightforward installation with matching system components.
