Product Description:

The MDD090B-N-020-N2L-130PL2 is a synchronous servo unit produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it works with matching motion modules to deliver closed-loop position and velocity control for machinery such as gantry axes and packaging stations. Its job in automation is to convert commanded current into precise rotary motion, while the integrated blocking brake holds the load when power is removed.

Mechanical interface data includes a 130 mm centering diameter that aligns the housing with gearboxes or machine frames, and factory balancing remains at a standard grade to reduce vibration within the rated speed range. At standstill, the rotor can provide 7.2 Nm of continuous torque, allowing the drive to hold or slowly index moderate loads without thermal overload. A built-in brake develops 11.0 Nm of torque so the shaft remains locked during power loss or emergency stops. Feedback is supplied through digital servo feedback (DSF), enabling the controller to read high-resolution position data over a single connector, and all power and signal conductors exit in the Left connection direction. The unit uses a sealed circular connector and a standard uncooled housing that fits compact installations.

The motor has a nominal speed of 2000 rpm, matching the torque-speed curve used for conveyors or indexing tables. The shaft uses a keyway to transmit torque, and a shaft seal helps keep lubricant from migrating into the motor interior. It is built in Motor Size 090 with length code B, giving it a medium frame that weighs less than larger MDD100 units while still using the standard shaft end without a side-B extension. The standard housing outline and integral connector also keep wiring clear of guards and nearby machine hardware.
