Product Description:

The MDD093B-N-020-N2M-130GL2 is a brushless synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for positioning tables, pick-and-place axes, and other automated machine movements. The integrated encoder uses a multiturn absolute measuring system, so the drive can read rotor position after power-up and maintain closed-loop accuracy without external feedback devices. This arrangement supports repeatable starts, controlled speed changes, and accurate positioning in machinery that operates through frequent cycle sequences.

At standstill, the motor delivers a continuous torque of 14.5 Nm, which allows it to support a steady load without exceeding winding temperature limits during normal operation. Under rated conditions, it runs at a nominal speed of 2000 rpm, making it suitable for applications that need stable operating speed during repeated production cycles. A blocking brake on the B-side provides 22 Nm of holding torque, helping keep a vertical axis or suspended load from drifting after power is removed. Installation is aided by a centering diameter of 130 mm, which helps align the motor accurately on the machine interface. Position information is transferred through digital servo feedback (DSF), allowing direct communication between the encoder system and the controller for coordinated motion control.

The motor uses standard dynamic balancing to help reduce vibration during acceleration and deceleration. Its frame size is 093, and the length code B identifies the housing length used for this version within that frame. Power and feedback cables exit on the left side through a sealed connector, which can simplify routing when the motor is mounted in cabinets or machine sections with limited cable space. The housing uses a standard unventilated design and includes a shaft seal, so the motor does not rely on a separate ventilation unit for cooling. Torque is transmitted through a plain shaft with no secondary shaft end, making it suitable for couplings, pulleys, gearboxes, and other directly driven machine elements.
