Product Description:

The MDD090A-N-040-N2M-110PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit converts electrical commands into controlled rotary motion for positioning and velocity tasks on automated machinery such as packaging axes, pick-and-place stations, or tool changers. Its synchronous design supports repeatable motion in closed-loop systems where accurate starts, stops, and speed changes are required during normal machine cycles.

Rated for a nominal speed of 4000 rpm, the rotor reaches this velocity when the drive supplies its rated voltage and frequency. At standstill, the electromagnetic system can deliver 3.7 Nm of continuous torque, allowing the axis to hold a working load without excessive thermal buildup during commanded zero-speed operation. For emergency stops or vertical axes, an integrated blocking brake provides 6.5 Nm of static holding torque to secure the shaft when power is removed. Mechanical alignment is aided by a centering flange diameter of 110 mm, and the motor uses frame size 090 for a compact body that fits space-limited machine sections.

Service connections leave the housing on Side A, and a sealed circular connector carries both power and encoder conductors to simplify cable routing. Position data is supplied through Digital servo feedback from an integrated multiturn absolute sensor, so the drive can retain shaft position information after power cycling. The output shaft uses a keyway for conventional hub coupling, and a shaft seal protects the internal bearings from contamination. The opposite end remains closed, which helps keep the overall motor length consistent with the A-length housing. This layout also reduces the number of separate cable entry points at the motor housing.
