Product Description:
The MDD090B-N-030-N2L-110PL1 is an AC synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts commanded current into controlled rotary motion for indexing tables, packaging axes, and material-handling gantries. Its synchronous design supports repeatable positioning and stable speed control in closed-loop motion systems, while the B-length housing keeps the motor compact enough for direct installation in space-limited machine frames. This layout makes it suitable for axes that must accelerate, stop, and hold position repeatedly during normal production cycles.
The motor supplies a continuous stall torque of 7.2 Nm, enabling it to hold loads steadily without overheating when the shaft is locked. During motion, the rotor can reach a nominal velocity of 3000 rpm, supporting rapid cycle times in automated equipment. A centering diameter of 110 mm aligns the stator accurately on the machine flange and helps reduce coaxial misalignment. All power and feedback plugs face the left side, which can simplify cable routing in multi-axis installations. Position data is returned through digital servo feedback, allowing the drive to close control loops at high resolution without an external encoder. This feedback arrangement lets the drive monitor rotor position directly during acceleration, constant speed, and standstill.
A rear-mounted holding brake applies 6.5 Nm of torque, so vertical axes can remain fixed when supply power is removed. The output shaft uses a keyway for positive torque transmission, and a shaft seal helps keep contaminants away from the bearing area. Wiring is routed through a single circular connector, which reduces the need for individual lead terminations at the motor housing. The motor uses a standard housing and standard balancing class, helping it run smoothly in compact automation equipment. This arrangement supports coupling to pulleys, gear inputs, and other driven elements without changing the basic motor package.
