Product Description:

The MDD090A-N-030-N2L-110PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for automated axes and spindles. Its synchronous design supports accurate speed control and responsive torque output during positioning, acceleration, and steady running in industrial machinery. It is intended for servo axes that must start, stop, and reverse smoothly during repeatable machine cycles.

This model delivers a continuous standstill torque of 3.7 Nm, so the drive can hold or slowly move loads without exceeding thermal limits. Its nominal speed is 3000 rpm, which is the reference running velocity maintained under rated conditions. Position and velocity data are returned through digital servo feedback (DSF), enabling the controller to close a high-resolution feedback loop. This feedback arrangement helps the controller monitor rotor movement in real time during speed regulation and position control. A shaft with a keyway interfaces directly with pulleys or couplings to reduce slip during acceleration. The motor has a length code A housing, and right-side power and feedback connections help keep cable routing orderly when drives are mounted on the machine's left.

A blocking brake supplies 6.5 Nm of holding torque whenever power is removed, which helps maintain axis position on vertical loads. The brake is useful when the axis must remain stationary after power loss. The centering pilot measures 110 mm, matching standard flange patterns, and a sealed electrical connector simplifies installation while protecting contacts from coolant or dust. Frame code 090 identifies the motor size, and the output end has a shaft seal to help keep oil or debris away from the bearing area. Standard dynamic balancing minimizes residual vibration. The housing uses the series' standard cooling surface design, and the shaft end is supplied only on side A. The right-hand connection orientation also suits modular cabinet layouts.
