Product Description:
The MDD090A-N-020-N2M-130PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the unit converts electrical commands into precise rotary motion for indexing tables, packaging axes, and other automated machinery. Its compact A-length housing and integrated encoder simplify installation in limited machine spaces and support closed-loop control without external feedback devices. This arrangement lets the drive monitor rotor position continuously, which supports repeatable starts, stops, and path corrections during automatic cycles.
Mechanical interface begins with a centering flange diameter of 130 mm, which helps align the motor accurately to gearboxes or machine frames. At standstill, the motor can deliver a continuous torque of 3.7 Nm, providing stable holding force during low-speed or stationary operation. The nominal rotor speed is 2000 rpm, making the motor suitable for applications that require moderate speed with accurate positioning. A blocking brake supplies up to 6.5 Nm of static torque, so vertical or suspended loads can remain secured when power is removed. The motor uses size code 090, identifying its frame size within the MDD range.
Dynamic balance is standard, which helps keep vibration low during normal operation and reduces the chance of unnecessary mechanical oscillation in coupled components. Power and feedback conductors exit on Side A, which can simplify cable routing when the drive-side connection is preferred. The motor uses a sealed keyway shaft for secure torque transmission, and the shaft seal helps protect internal bearings from dust or coolant. Position data is provided by an integrated multi-turn absolute encoder, and that signal is transmitted through digital servo feedback (DSF) to the connected drive controller. Because the encoder stores absolute position over multiple revolutions, the system can resume with immediate position awareness instead of relying only on incremental pulse counting.
