Product Description:

The MDD090A-N-040-N2M-130PL0 is a synchronous AC servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for direct use with digital drive controllers, this unit converts commanded current into proportional torque for precise position and velocity control in automated assembly lines, pick-and-place modules, and material handling systems. Its compact A-length housing and standard balancing support installation in tight machine spaces while helping keep vibration low during operation. A standard housing finish supports use in typical industrial surroundings, and the motor is suited to applications that need accurate rotary motion without an oversized mechanical package.

It delivers a continuous standstill torque of 3.7 Nm, so the shaft can maintain load at zero speed when cooling conditions are appropriate for the motor. Under rated electrical frequency, the rotor reaches a nominal speed of 4000 rpm, providing a wide operating range for indexing and interpolated motion. Accurate mechanical locating is supported by the 130 mm centering diameter, which fits compatible flange faces. Command feedback is produced by the built-in integrated multi-turn absolute encoder, and position data is transmitted through Digital servo feedback (DSF) to the drive. The motor is supplied without a blocking brake, so vertical or suspended loads require external holding force or drive-applied torque when the axis is stopped.

The motor uses frame size 090 with the series A-length core, which keeps the overall body short while maintaining the intended torque output for this frame. Power and feedback connections are placed on the left side and use a sealed connector, which helps cable routing inside compact enclosures. The output shaft uses a keyway for positive torque transmission to a mating hub or coupling. It is equipped with a shaft seal, which helps limit lubricant escape and the entry of contamination. A standard single-ended shaft is provided, with no side-B extension, so the motor keeps a straightforward mechanical layout for common drive assemblies.
