Product Description:

The MDD090A-N-040-N2M-130PB0 is a synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts electrical commands into precise rotary motion for positioning and speed-control tasks in automated machinery. In closed-loop axes, the motor provides the torque and speed accuracy required in packaging lines, pick-and-place gantries, and other production equipment that demands repeatable, program-driven motion. This makes it suitable for applications that depend on accurate indexing and stable response during frequent starts, stops, and direction changes.

The motor uses a centering diameter of 130 mm for alignment to mounting flanges and standard balancing to limit vibration at rated speed. At standstill, it can deliver 3.7 Nm of continuous torque, giving the drive holding capability when motion is paused. The rotor is optimized for a nominal speed of 4000 rpm, allowing rapid cycles without exceeding thermal limits for the size-090 frame. Power and feedback cabling exit on side B through a connector, which simplifies routing where space behind the motor is limited. The housing and shaft end use the standard version, and motor length code A indicates the most compact build in the 090 diameter class.

Signal quality is maintained by an integrated multi-turn absolute encoder, which returns absolute rotor position across multiple revolutions, while the drive interprets this data through digital servo feedback (DSF) for tight loop regulation. Absolute position data is available immediately after startup, which supports applications that need position awareness over more than one revolution. The motor uses a keyway shaft for torque transfer to pulleys or couplings, which suits common machine-drive connections. It also has a shaft seal, which helps keep lubricant in place and reduces the entry of airborne particles into the bearing cavity. The motor is supplied without a blocking brake, so static loads must be secured externally or by drive torque when power is off.
