Product Description:

The MDD090B-N-040-N2L-110GB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and delivers commanded rotary motion for automated machinery that requires controlled speed and position in assembly cells, material-handling axes, and packaging stations. Position data returns through digital servo feedback, allowing the controller to regulate motion in closed loop during acceleration, steady running, and stopping. This arrangement supports repeatable axis movement where accurate tracking and stable response are required throughout the duty cycle.

Its nominal speed is 4000 rpm, which allows direct coupling to moderate-ratio gearsets without exceeding the motor’s intended operating range. At standstill, the windings can produce 7.2 Nm of continuous torque, so the axis can support process loads without excessive heat rise during normal duty. A factory-mounted blocking brake provides 6.5 Nm of holding torque when power is removed, which helps keep vertical or suspended loads from drifting at rest. Mechanical alignment is aided by a centering diameter of 110 mm, and the power and feedback leads exit on Side B through a keyed connector that keeps the electrical interface compact. This cable exit arrangement can help routing in installations where space around the motor body is limited.

The rotor uses standard balancing, which supports smooth running when the motor is coupled to compliant loads. To reduce fluid entry at the drive end, the motor includes a shaft seal and uses a plain shaft for torque transmission. Frame size 090 with length code B corresponds to the standard housing layout used for this motor platform, so the flange and bolt pattern remain consistent with that frame. The opposite end does not have a second shaft extension, leaving the motor with a single-ended output shaft.
