Product Description:

The MDD090B-N-030-N2L-110GA0 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for positioning tables, pick-and-place axes, and similar automated equipment where commanded current must be converted into tightly regulated torque. The motor is built for use with digital drive controllers, giving the control system the electrical and motion characteristics needed for accurate axis operation. Its format also supports compact machine layouts that require repeatable movement over frequent operating cycles.

Under continuous stall conditions, the motor delivers 7.2 Nm of torque, while velocity regulation is available up to a nominal speed of 3000 rpm. A 110 mm centering diameter aligns the flange with machine frames, and a shaft seal helps protect the plain shaft from coolant splash or dust ingress. Standard dynamic balancing keeps vibration low during normal operation, and the housing uses a standard design without added fins or special cooling channels. Power and feedback conductors share a single connector interface, which keeps the connection area compact. The plain shaft does not include a side B extension, allowing direct coupling to belt pulleys or rigid clutches.

Digital control loops rely on the integrated digital servo feedback encoder for rotor position and speed data. Cables leave the unit on side A, which can simplify routing when the motor face is mounted toward the machine structure. The motor is supplied without a blocking brake, so any holding function must come from the drive or external mechanics. The electrical terminals use a compact connector rather than loose leads, which helps in tight cabinets. With a frame size of 090 and a length code of B, the motor fits mid-range load requirements while keeping inertia moderate for responsive starts and stops.
