Product Description:
The MDD090B-N-030-N2L-130GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for operation with digital drive controllers, the unit supplies regulated torque and speed to automated machinery in packaging, material-handling, and assembly cells. It is intended for closed-loop axes that need stable rotary motion during indexing, positioning, and hold periods. Its 090 frame with length code B gives the motor a compact envelope, and the integrated blocking brake keeps the load immobile whenever power is removed. The motor is suitable for applications that require repeatable speed regulation and controlled load holding during normal machine cycles.
At stall, the motor can deliver a continuous torque of 7.2 Nm, allowing it to support static loads without overheating during rated operation. When commanded to full speed, it reaches a nominal speed of 3000 rpm, which suits rapid cycle tasks on many automated axes. The blocking brake develops 11.0 Nm of torque, so the axis can remain locked during stops or power loss. Mounting accuracy is aided by a centering diameter of 130 mm, which helps align the motor precisely with machine interfaces. Size code 090 matches the mechanical envelope used for this frame. Standard balancing helps limit residual vibration, and the housing dissipates heat through natural convection. The shaft end has no side-B extension, which reduces overall length and simplifies coupling layout.
Electrical power and feedback cables exit on the right side of the housing through a connector, which allows quick cable changes and keeps the connection point easy to access. Rotor position is reported by integrated digital servo feedback, so the controller receives motor position information immediately after power-up. The motor uses a plain shaft that accepts keyed hubs or clamp collars, and a dedicated shaft seal helps prevent lubricant migration into the motor interior. The right-side cable exit also helps in machine layouts where the rear of the motor sits close to guards or mounting plates. The housing style remains compatible with guarded installations that rely on open space around the outer fins rather than internal ducting.
