Product Description:

The MDD090B-N-020-N2L-110GR2 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is designed to work with digital drive controllers, converting commanded current into controlled rotary motion for positioning and speed-controlled machine axes. Integrated feedback electronics support closed-loop operation, and the built-in blocking brake helps hold the load when drive power is removed. Because these functions are contained in the motor, the axis can start, stop, and hold position without separate external feedback hardware. It is suited for positioning duties and regulated speed tasks in automated handling, packaging, and similar production equipment. This arrangement is useful on automated equipment where the shaft must remain stable during pauses or power-off conditions.

In continuous operation, the rotor delivers 7.2 Nm of torque and reaches a nominal speed of 2000 rpm with a matching inverter. The internal brake provides 11.0 Nm of holding torque, so the axis can remain stationary without continuous winding current. Position and velocity data are transmitted through digital servo feedback (DSF), which allows the controller to regulate motion accurately and respond to changing load conditions. This feedback path supports both motion accuracy and stable speed regulation. A centering diameter of 110 mm helps the motor align precisely with machine flanges or gearbox interfaces. That pilot fit also supports repeatable mounting when the motor is installed in tightly aligned drive trains.

Cables exit on the right side of the housing and terminate through a connector, which keeps electrical disconnection straightforward when the motor is removed from the machine. The output uses a plain shaft with a shaft seal, allowing torque transfer through an external coupling while helping limit contaminant entry and lubricant migration at the drive end. The motor has no side-B shaft end, which helps reduce installation depth in compact assemblies. A balanced rotor helps keep vibration low during rotation, and the housing follows the standard enclosure style used in the series. It is built in frame size 090 with length code B, placing it in a mid-range package for automated motion systems.
