Product Description:

The MDD090B-N-040-N2M-110GR0 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it acts as the rotary actuator in closed-loop positioning and speed-control tasks found in packaging lines, pick-and-place axes, and machine tool spindles. Its electromechanical design converts precisely modulated stator currents into controlled torque, allowing the drive to synchronize motor motion with command setpoints inside an automated cell. This arrangement supports repeatable motion on axes that must accelerate, decelerate, and settle accurately during continuous machine cycles.

At a nominal speed of 4000 rpm, the rotor can sustain rated velocity without exceeding thermal limits, while a continuous standstill torque of 7.2 Nm is available when the shaft is locked. Installation to a gearbox or frame is centered by the 110 mm register, which helps align the motor housing with the driven assembly. Power and feedback conductors enter through a right-side connector, which can simplify cable routing where side clearance is available. Command loops rely on Digital servo feedback (DSF) that sends high-resolution position data to the drive so speed and position errors can be corrected quickly during motion. The size 090 frame, motor length code B, a standard aluminum housing, and the right-side connection orientation keep the package compact for tight mounting spaces.

An Integrated multiturn absolute encoder tracks position across multiple revolutions without battery support, so the controller can retain position information after power interruption. Contaminant ingress is reduced by a shaft seal at the coupling face, and torque is transmitted through a plain shaft that omits keys for slip-fit couplings. This shaft style suits clamping elements that grip the shaft surface directly instead of using a keyed connection. The shaft terminates only on side A, while the side B end is omitted to reduce overall motor length. Because the motor is supplied without a blocking brake, external locking devices are required whenever static holding torque must be maintained after power is removed.
