Product Description:

The MDD090A-N-040-N2L-110PB2 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides rotary motion that can be precisely regulated by matching drive electronics in automated machinery. The unit follows motor size 090 and the compact motor length code A, making it suitable for installations where space is limited and responsive motion is still required. This layout is useful where adjacent machine components leave little room around the motor body. An integrated blocking brake allows the axis to remain fixed when power is removed during handling or positioning tasks.

The motor reaches a nominal speed of 4000 rpm, supporting rapid cycle rates in pick-and-place and packaging equipment. At standstill, it can deliver a continuous torque of 3.7 Nm without thermal overload. For short-term clamping or emergency stops, the brake supplies 11.0 Nm of braking torque. Rotor position is reported through digital servo feedback, enabling high-resolution speed and torque control by the drive. Power and feedback conductors exit on side B of the housing, a layout that can simplify wiring in multi-axis cabinets with shared cable ducts.

A centering diameter of 110 mm aligns the flange accurately on the machine frame for repeatable mounting. The shaft uses a keyway profile so pulleys or couplings can transfer motion without slip, and a shaft seal helps keep lubricants inside while blocking dust ingress. Internally, the rotor uses standard balancing to reduce vibration at rated speed. The housing is supplied in the standard configuration, the shaft end is limited to the drive side only, and connections are made through a molded connector that keeps the electrical interface compact at the motor housing. The single shaft end keeps the output arrangement straightforward for direct coupling to external transmission elements.
