Product Description:

Bosch Rexroth Indramat builds the synchronous servo motor MDD090A-N-020-N2L-130GA0 for use in automation systems that rely on digital drive controllers. As a member of the MDD Synchronous Motors series, the unit converts electrical power from a drive into controlled rotary motion that can be coordinated with encoder feedback for positioning or velocity loops on production machinery. This type of motor is commonly used on feed axes, transfer units, and handling equipment where repeatable acceleration and stable closed-loop operation are required throughout regular production cycles.

The motor delivers a continuous standstill torque of 3.7 Nm, giving the drive enough static force to hold loads without external gearing when the shaft is energized. Its nominal speed of 2000 rpm is the upper steady-state velocity reached under rated current, which helps match mechanical transmission ratios. A centering diameter of 130 mm aligns the housing precisely on mounting flanges to keep the rotor air gap uniform. Position data is returned through Digital servo feedback (DSF), allowing the controller to close a high-resolution loop for accuracy in indexing or contouring tasks. The motor is supplied without a blocking brake, so any power-off holding requirement must be handled by the machine’s mechanics or by maintaining drive torque.

Cables exit on Side A, and the power and feedback lines are joined through a keyed Connector that supports quick removal when the motor is disconnected. A standard housing with symmetrical mass distribution meets the Standard balancing class to minimize residual vibration at full speed. The motor has length code A, while the 090 frame size fits applications with moderate footprint limits. A single plain shaft transmits torque, and it uses a standard shaft end without an extension on side B to reduce overhung load. Contaminants are kept out of the front bearing region with a shaft seal, which helps preserve lubrication when the motor operates in oily or dusty environments.
