Product Description:

The MDD090B-N-020-N2M-110PR2 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series and is intended for use with digital drive controllers on automated axes. As a motor for digital drive controllers, it supports closed-loop motion because position data is returned to the drive. In industrial automation, the motor converts electrical energy into rotary motion so the controller can regulate velocity, torque, and stopping functions in packaging, material handling, and machining equipment. This makes it suitable for axes that need controlled acceleration, steady speed holding, and accurate stopping under changing load.

The motor uses the B length code in the 090 frame and a standard housing with standard balancing. A centering diameter of 110 mm aligns the flange accurately on the mounting surface, and cabling exits through a right-side connector that helps keep routing orderly. Under continuous stall conditions, the shaft can sustain 7.2 Nm of torque without exceeding thermal limits, while normal operation reaches a nominal speed of 2000 rpm. Feedback is handled by Digital servo feedback (DSF), which supplies incremental position data for velocity regulation and coordinated axis motion. The housing depth keeps the motor compact while preserving access to the mounting face and cable connection.

A mechanical blocking brake rated at 11.0 Nm holds the rotor when drive power is removed, which helps prevent unintended motion on vertical or suspended loads. Shaft position is retained by the integrated multiturn absolute encoder, so the axis can recover its position after a power cycle without a homing move. The motor uses a keyway shaft for torque transfer, and the shaft seal helps protect the bearing area from contamination while keeping lubricant in place. It is supplied with a standard shaft end without side B extension, which keeps the rear of the motor compact for installations with limited clearance. The single-ended shaft layout is useful where the back of the motor sits close to a mounting plate or guard.
