Product Description:

The MDD090B-N-020-N2M-130GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for integration with digital drive controllers, it converts electrical command signals into precise rotary motion for automated machinery and material-handling axes. The motor is intended for use with digital drive controllers and provides closed-loop performance for tasks that require repeatable positioning, stable speed regulation, and accurate response to changing loads in industrial automation lines. This operating concept supports coordinated motion on packaging equipment, transfer systems, and other industrial machines that rely on controlled rotary movement.

Standard dynamic balancing reduces vibration when the rotor is coupled to downstream mechanics, and the centering register measures 130 mm, giving a stable interface to gearbox flanges or mounting brackets. Power and feedback leads exit on the Left side, and termination is through a keyed Connector. At standstill, the electromagnetic design sustains 7.2 Nm of continuous torque, while the winding and magnetic circuit support a base speed of 2000 rpm for steady production cycles. The motor has size 090 with length code B, and the cast-aluminum housing is standard for this frame class while supporting consistent heat dissipation during continuous operation.

Signal functions are handled by an integrated multi-turn absolute encoder that reports angular position across multiple revolutions, and the drive receives this information over digital servo feedback for high-resolution control loops. The rotor uses a plain shaft and includes a shaft seal that limits lubricant migration toward the motor interior. Because the unit is supplied without a blocking brake, an external holding device is required when power-off braking is needed. The shaft end is supplied only on side A, avoiding extra overhang on the opposite face. The product is intended for use with controllers that monitor embedded temperature sensors to help protect insulation during continuous duty.
