Product Description:

The MDD090A-N-020-N2M-130PB0 is a synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it provides rotational power to axes that require coordinated motion in machining centers, handling modules, and packaging equipment. When paired with a compatible servo drive, the unit converts commanded current into torque so that mechanical loads can be positioned or held with repeatable accuracy across an entire duty cycle. This operating role suits servo axes that must accelerate, decelerate, and settle accurately during repeated machine cycles.

The motor’s nominal speed is 2000 rpm, indicating the shaft velocity it can reach under rated electrical and thermal conditions without exceeding permissible losses. At standstill, it develops a continuous torque of 3.7 Nm, allowing static load support while thermal equilibrium is maintained. Power and feedback conductors exit on side B and terminate through a sealed connector interface, which helps keep wiring organized at that face of the motor. Rotor position is reported by an integrated multi-turn absolute encoder, giving the drive unambiguous position data over multiple revolutions and supporting immediate position recognition after power-up.

A centering diameter of 130 mm aligns the flange to machine frames and helps keep runout within permitted limits. Motion commands are closed through digital servo feedback (DSF), which transmits high-resolution encoder signals to the controller for precise regulation. The shaft is protected by a shaft seal that helps keep lubricants or coolants out of the bearing area, and torque is delivered through a keyway shaft end that mates to standard hub keys. Standard balancing helps limit residual vibration, while the standard housing provides a familiar mounting footprint. The unit is supplied without a blocking brake, so external holding torque is required when the motor is de-energized, and Motor Length Code A within the 090 frame size keeps the overall length compact for tightly packed multi-axis assemblies.
