Product Description:

The MDD115B-N-020-N2L-130PB1 synchronous motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is classified as a motor for digital drive controllers and is installed in automated production lines to convert regulated electrical power into precise rotary motion for positioning tasks and coordinated axis movement. Its synchronous design supports accurate response to commanded speed and position changes during closed-loop operation.

At the core of this model is a continuous standstill torque of 38.0 Nm, enabling the drive to hold static loads without overheating while current flows through the stator windings. Under rated excitation, it reaches a nominal speed of 2000 rpm, matching drives that supply synchronized sinusoidal currents for medium-speed processes. A blocking brake is integrated, delivering a holding torque of 45.0 Nm so vertical or suspended axes remain locked when the inverter is disabled. The centering shoulder measures 130 mm in diameter, providing a rigid fit to machine frames, and the motor size is 115. Standard rotor balancing minimizes residual vibration, the B length code identifies the electromagnetic stack depth, and the standard housing dissipates heat through natural convection. Feedback is supplied through digital servo feedback for high-resolution position control, while the single-ended shaft comes without a secondary output on side B.

The electrical terminations are oriented toward Side B, and power plus encoder signals are delivered through a single industrial Connector that streamlines cabinet wiring. A factory-installed keyway shaft interface transmits torque to pulleys or couplings without slip, and there is a shaft seal at the output face to guard the interior against coolant mist and fine dust. This arrangement supports general-purpose automation equipment that requires protected shaft output and orderly cable routing.
