Product Description:

The MDD090B-N-020-N2L-130GA1 is a permanent-magnet synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary element of a closed-loop servo axis driven by a digital controller, converting electrical commands into precise torque and speed for industrial positioning, packaging, or machine-tool applications. The motor housing follows a standard frame layout that integrates easily on modular mounting plates in compact machine assemblies.

At stall, the motor can supply 7.2 Nm of continuous torque, allowing low-speed holding or indexing without excessive heating. During motion, it reaches a nominal speed of 2000 rpm, which matches drive controllers calibrated for moderate-speed axes such as feed rollers or automated gantry joints. Mechanical alignment is simplified by a centering shoulder of 130 mm diameter, ensuring concentric seating inside geared housings or belt pulleys. The integrated blocking brake applies up to 6.5 Nm of retention torque so vertical loads remain stationary when the drive is disabled. All power and feedback connectors exit on side A, letting cabinet wiring stay on one face of the machine and keeping service space clear on the opposite side.

Signal quality is maintained through digital servo feedback, which supplies high-resolution position data to the controller for tight velocity and torque loops. The motor is categorized in frame size 090, giving a rotor diameter compatible with medium-inertia axes while still fitting inside compact mechanical envelopes. Its output shaft is a plain shaft that mates with clamping couplings or keyed hubs selected for the application, and a shaft seal helps prevent lubricant or coolant from reaching the front bearing. Standard dynamic balancing minimizes vibration across the speed range, and the single-ended shaft design eliminates the need for additional guarding at the rear of the motor.
