Product Description:

The MDD090B-N-040-N2M-130PL1 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for closed-loop motion axes in industrial automation where digital drive controllers require precise torque and speed regulation. The motor operates as the mechanical actuator in systems such as pick-and-place gantries, packaging stations, or printing lines, converting drive current into controlled rotary movement. In these applications, it works with a compatible digital drive to deliver repeatable acceleration, deceleration, and holding behavior.

This model supplies a continuous standstill torque of 7.2 Nm, allowing static load support during low-speed holding tasks. Dynamic applications are aided by a nominal speed of 4000 rpm, which suits rapid indexing and high cycle rates. Mechanical alignment is simplified by a centering diameter of 130 mm, and the rotor is balanced to the standard grade to reduce vibration during operation. All power and feedback leads exit on the left side, and the electrical interface uses a single circular connector to keep cable routing orderly. The standard housing encloses a size 090 stator assembly and B length code, providing the thermal mass needed to maintain rated torque without forced cooling.

A blocking brake integrated at the non-drive end can apply 6.5 Nm of static torque to secure vertical loads when the drive is disabled. Position reporting comes from an integrated multiturn absolute encoder, and rotor data are sent to the controller as digital servo feedback for immediate correction of speed and position errors. The shaft features a keyway to transmit torque to couplings, and a shaft seal helps prevent lubricant migration into the motor interior. The motor uses a standard single-ended shaft without a side B extension, which keeps the overall length compact. This arrangement supports direct connection to digital drive controllers without added external sensing hardware.
