Product Description:

The MDD090C-N-040-N2L-110PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It functions with digital drive controllers, converting commanded current into rotary motion for positioning and velocity tasks in automated machinery. The motor uses frame length C and a standard housing suited to installation on machine frames or in enclosed industrial assemblies. It is intended for motion systems that require repeatable acceleration and stable closed-loop control during continuous production cycles.

This motor delivers a continuous standstill torque of 10.4 Nm, allowing holding or low-speed operation without overheating. Its nominal operating speed reaches 4000 rpm, giving the drive system a wide mechanical bandwidth for rapid indexing and responsive speed changes. A centering diameter of 110 mm aligns the flange precisely with mating machine surfaces to help maintain shaft alignment during operation. Rotor position is reported through Digital servo feedback (DSF), so the connected controller can close high-resolution motion loops. The motor is supplied without a blocking brake, so applications that require static holding torque must use an external clamp or maintain drive current. Dynamic balancing is standard, which supports smooth running in general-purpose machinery.

All electrical terminations are routed on Side B through a single connector that carries both power and feedback, which simplifies cable routing and reduces separate entry points at the housing. The output shaft uses a keyway so couplings or pulleys can transmit torque without slip during acceleration and deceleration. The shaft also includes a shaft seal that helps limit lubricant migration and the entry of dust near the bearing area. The motor uses frame size 090, and the design has no second shaft at the opposite end, which helps keep the overall length compact.
