Product Description:

The MDD090C-N-040-N2M-110PR0 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for integration with digital drive controllers, it converts electrical energy into controlled rotary motion for positioning, conveying, or tool-handling stations on automated lines. Its closed-loop design supports accurate motion on machines that require repeatable speed and position control. This type of motor is well suited for applications that depend on smooth acceleration, controlled deceleration, and consistent axis response during repeated cycles.

At standstill, the rotor can deliver a continuous torque of 10.4 Nm, providing steady torque for static load holding without thermal overload. During rated operation, the shaft reaches a nominal speed of 4000 rpm, allowing fast cycle movements when the drive controller supplies the matching synchronous frequency. The motor has a centering diameter of 110 mm for accurate location on precision mounting surfaces. Power and feedback conductors exit on the right side through a sealed connector, which keeps the cable interface compact and protected.

The motor has frame size 090 and length code C, so its active stack fits medium-power axes without enlarging the machine envelope. Motion data is returned through Digital servo feedback (DSF), and the integrated encoder supplies multiturn absolute position information after power loss. This allows the control system to recover position data without relying only on incremental feedback. A shaft seal helps protect the internal laminations from coolant spray, and the output shaft uses a keyway for secure coupling. The motor is delivered with standard balancing, a standard housing, and a shaft end only on side A, leaving side B closed. Because it is shipped without a blocking brake, hold-position demands must be met by the drive or an external brake module.
