Product Description:
The MDD090A-N-040-N2M-110GB1 is an AC permanent-magnet servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into controllable torque and speed for automated robots, pick-and-place gantries, and high-speed tooling spindles. Its electromechanical design works with Indramat drives to close the velocity and position loops required in modern production cells, so the axis can respond accurately during repetitive motion and rapid load changes. This motor style is commonly used where precise acceleration, steady low-speed control, and repeatable stopping are needed across frequent start-stop cycles.
A centering lip of 110 mm matches common machine interfaces, and the size 090 housing with compact A length helps the motor fit installations where axial space is limited. Power and feedback conductors exit on side B, and a single keyed connector carries both circuits to simplify cable routing at the rear of the machine. When mounted to a suitable heat sink, the motor can deliver 3.7 Nm of continuous standstill torque, and the rotor can operate up to 4000 rpm during normal running. The drive-side shaft is arranged for direct coupling to servo gearheads, while the lack of a second shaft end keeps the rotating assembly shorter and reduces unused overhang. This arrangement leaves the front face clear for flange alignment and nearby mechanical components.
Position monitoring relies on integrated digital servo feedback (DSF), allowing the controller to recover absolute angle information immediately after power is restored and eliminating the need for a homing move in many installations. For static holding, a blocking brake rated at 6.5 Nm engages automatically to secure vertical or oscillating loads when drive power is removed. The motor uses a plain shaft finished to ISO tolerances, and it is supplied with a shaft seal to help protect the bearing area from coolant or oil migration along the shaft journal.
