Product Description:

The MDD090A-N-040-N2M-110GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and provides closed-loop rotary motion in industrial automation cells. The motor converts commanded electrical input into repeatable shaft movement for pick-and-place gantries, packaging stations, and light conveying duties. In servo applications, this supports accurate positioning, stable speed regulation, and predictable response to changing loads.

Rated for a nominal speed of 4000 rpm, the unit has a standstill torque of 3.7 Nm. An integrated blocking brake can apply up to 11.0 Nm to resist back-driving during power-off conditions. A centering diameter of 110 mm helps align the motor on the machine interface, and position data is sent to the drive through digital servo feedback. Electrical terminations exit on Side A, which keeps cable routing on one face of the housing and can reduce cable crowding near adjacent machine components. The motor uses size code 090 and a standard housing form, and a standard rotor balance supports smooth running during high-speed cycles.

The electromechanical interface includes an integrated multiturn absolute encoder that provides 32-bit position data for multi-revolution tracking. Because the encoder tracks movement across multiple turns, the drive can maintain shaft position information throughout extended motion sequences. Power and feedback lines connect through a keyed connector, which keeps the interface secure and compact. The output uses a plain shaft with a factory-installed shaft seal, supporting friction-fit couplings while helping keep contaminants away from internal components. Motor length code A indicates the shortest stack in this frame size, and the shaft is provided only on the drive side to reduce overhung mass.
