Product Description:

The MDD090B-N-020-N2M-130PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is built for use with digital drive controllers, where commanded inverter current is converted into controlled rotary motion for positioning axes and regulated speed applications. Because it works with digital control, current, speed, and position loops can be adjusted through the connected controller rather than through analog signal conditioning. This makes the motor appropriate for assembly lines, packaging machines, and material-handling systems that require repeatable starts, stops, and steady motion during normal machine cycles.

The motor develops a continuous standstill torque of 7.2 Nm, allowing it to hold commanded position at zero speed without excessive heating. During power-off or emergency conditions, the brake provides 6.5 Nm of holding torque to keep the shaft from turning under static load. Rated operation is centered on a nominal speed of 2000 rpm, which gives a useful balance of dynamic response and thermal performance for this frame size. Rotor position is supplied by an integrated multiturn absolute encoder, and motion data is transmitted through digital servo feedback (DSF) for stable closed-loop control without analog drift. The feedback arrangement lets the drive monitor shaft movement continuously during acceleration, steady running, and braking.

A centering diameter of 130 mm aligns the flange accurately with machine interfaces, and all power and feedback conductors exit on Side A to simplify cable routing where space is limited. That cable orientation can reduce bend stress near the motor when several axes are mounted close together. The output shaft uses a keyway for positive torque transmission, and a shaft seal helps limit lubricant leakage and contaminant entry during operation. The frame designation 090 with length code B indicates the motor's electromagnetic stack size and overall housing format. The single-shaft layout keeps the package compact, and the connector-based wiring arrangement supports orderly installation in multi-axis equipment.
