Product Description:

The MDD090A-N-030-N2M-110PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for industrial automation. As part of the MDD Synchronous Motors series, it works with digital drive controllers to convert commanded current into controlled rotary motion for closed-loop axes. Its 090 frame and compact A length suit medium-inertia mechanisms where accurate positioning and repeatable speed control are required. The standard housing and standard dynamic balancing make it appropriate for machine axes that need predictable mechanical behavior during frequent starts and stops. It is commonly used on feed axes, handling units, and compact processing stations.

At a nominal speed of 3000 rpm, the rotor maintains commanded velocity during normal servo operation. A continuous standstill torque of 3.7 Nm lets the motor hold a stationary load while current is applied. For power-off holding, the blocking brake provides 11.0 Nm of mechanical holding torque. A centering diameter of 110 mm supports accurate alignment at the mounting face. The drive receives position information through Digital servo feedback (DSF), allowing the speed and position loops to respond to shaft movement in real time. This operating profile suits indexing, feeding, and other applications that need controlled motion and dependable holding behavior.

Position sensing is provided by an internal integrated multi-turn absolute encoder, so absolute position remains available over multiple revolutions. Torque is transmitted through a shaft with a keyway, which supports secure coupling to pulleys, pinions, or hubs. Power and feedback cables exit on side B through a sealed connector, helping keep wiring concentrated on one side of the motor. A shaft seal helps reduce the entry of contaminants along the shaft during operation. The motor has no second shaft end, which shortens the overall package and avoids unused rotating hardware in compact machine layouts.
