Product Description:

Bosch Rexroth Indramat manufactures the MDD090A-N-030-N2L-130PL0 as part of the MDD Synchronous Motors series. The unit is classified as a motor for digital drive controllers, meaning it receives current-regulated pulses from an Indramat inverter and produces controlled torque for positioning and velocity loops. With its 090 frame size and compact A length construction, the motor fits mid-range workstations where fast acceleration and repeatable speed are required. This arrangement allows the paired drive to regulate axis motion during repetitive operating cycles. It is used in presses, pick-and-place gantries, and other automated assemblies that require controlled servo motion.

At standstill, the rotor can deliver 3.7 Nm of continuous torque, giving the axis sufficient holding force for indexing or low-speed feed tasks. Once the drive ramps to its rated velocity of 3000 rpm, the magnetic circuit sustains smooth rotation with the motor’s standard dynamic balancing. Position data is returned through digital servo feedback (DSF), allowing real-time correction inside the control loop. That closed-loop feedback supports stable positioning during rapid start-stop cycles. All power and feedback conductors exit on the left side of the housing, and a sealed connector simplifies cable replacement without rewiring the cabinet.

The flange centers on a 130 mm pilot, matching gearboxes that use the same datum. The shaft uses a keyway for torque transmission, and a shaft seal helps keep lubricants out of the motor interior. This layout supports direct coupling to machine elements that require positive mechanical engagement. Because the unit is supplied without a blocking brake, the axis must rely on drive torque or external clamps to hold position during power-off states. The A length code indicates the compact stack used with the standard housing and single-ended shaft, which helps limit weight while accommodating digital feedback electronics.
