Product Description:

The MDD115A-N-020-N2L-130GR1 is a synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it connects directly to servo inverters and converts commanded current into precise rotary motion for positioning and cyclic-duty industrial axes. Its synchronous design supports accurate speed and position control during repeated starts, stops, and reversals. The standard housing and balancing make it suitable for installation in general-purpose machine frames, and the integrated blocking brake helps hold the load when power is removed.

The motor reaches a nominal speed of 2000 rpm, which is its continuous rotor speed under rated electrical conditions. It provides 28.0 Nm of continuous standstill torque, so the shaft can remain energized at zero speed without thermal overload in normal operation. During emergency stops, the blocking brake provides 45.0 Nm of holding torque to resist back-driving on suspended or vertical axes. Feedback is supplied by digital servo feedback (DSF), allowing the controller to monitor rotor position and speed for closed-loop motion control. Electrical connections are arranged on the right side, which can simplify cable routing when the motor is installed with power and feedback cables entering from that direction.

A centering pilot of 130 mm aligns the flange accurately with mating mounts and helps support consistent mechanical fit. Frame size 115 uses a larger stator cross-section for medium-torque servo duty, while the short A-length housing helps save axial space. The motor uses a plain shaft, which omits a keyed coupling surface and is suited to friction-locking hub connections. It also has a shaft seal to help limit lubricant migration and reduce dust entry at the shaft exit. This combination supports clean mechanical integration where coupling alignment is controlled by the mating hub and flange mounting surface.
