Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-020-N2M-110GR0 in its MDD Synchronous Motors series. The unit is a permanent-magnet synchronous motor engineered to pair with digital drive controllers and provide closed-loop rotary motion in industrial automation lines. By converting controlled three-phase current into torque, the motor drives axes in packaging, material-handling, and machining equipment where repeatable positioning and stable speed are required. Its synchronous design supports accurate response to command changes, so the drive can regulate motion with low lag during indexing, feed movements, and other cyclic tasks.

The motor sustains a continuous standstill torque of 7.2 Nm, allowing it to hold loads without overheating while stationary. Under rated electrical frequency, the rotor reaches 2000 rpm before field weakening is required. Accurate mechanical seating is provided by a 110 mm centering diameter that mates with standard machine flanges. Frame size 090 indicates the motor size, and length code B identifies the active core depth used for this model. Standard balancing reduces residual vibration during rotation, the housing is standard cast aluminum, and a plain shaft end without a side-B extension simplifies coupling alignment where axial space is limited.

Cabling enters from the right side because the power and feedback terminals are grouped on that flank in a single connector shell. Position data are generated by an integrated multiturn absolute encoder that transmits through digital servo feedback, allowing the controller to recover shaft angle after power cycles and maintain closed-loop operation across speed changes. The rotor is supplied without a blocking brake, so any vertical axis must use an external holding mechanism. A shaft seal helps protect against oil ingress, and the plain shaft geometry simplifies pulley or coupling installation in machines that need direct motor mounting.
