Product Description:

The Bosch Rexroth Indramat MDD090A-N-040-N2M-130GR0 is a synchronous servo motor from the MDD Synchronous Motors series. It is intended for use with digital drive controllers and supplies rotary motion to axes that require precise speed and position regulation. In automated systems, the motor works with a compatible Indramat drive to convert electrical commands into controlled mechanical motion for conveyors, pick-and-place units, and tooling assemblies. This type of motor is commonly used where the controller must keep axis motion repeatable during frequent starts, stops, and direction changes.

Its mechanical layout includes a centering diameter of 130 mm, motor size 090, and a compact A-length housing that keeps overall mass low while retaining a standard enclosure. The centering shoulder helps locate the motor accurately on the machine mounting face, which supports consistent alignment during installation. The rotor is balanced to a standard grade for normal operation. Under continuous stall, the stator produces 3.7 Nm of torque, and the rotor can reach a nominal speed of 4000 rpm during operation. Electrical and signal leads exit on the right side through a single industrial connector, and the output uses a plain shaft for coupling.

Position and speed loops are closed by an integrated multi-turn absolute encoder, while the drive receives incremental and absolute data through the digital servo feedback channel. This feedback arrangement allows the drive to track rotor position across multiple revolutions and maintain stable closed-loop control. For applications that use external braking or vertical load counterbalancing, the motor is supplied without a blocking brake, so any holding function must be provided by the machine or the drive system. A shaft seal helps limit the entry of oil mist and fine dust into the housing.
