Product Description:

The MDD093B-N-040-N2M-130GB0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into proportional mechanical motion for positioning and speed-control tasks on automated machinery. Its balancing is standard, and the housing uses standard construction for general industrial applications that rely on closed-loop digital feedback.

At the electrical level, the motor can sustain a continuous standstill torque of 14.5 Nm, allowing static holding or low-speed trimming without overheating. At rated excitation, it reaches a nominal speed of 4000 rpm, so rotary axes can achieve fast indexing while maintaining servo accuracy. Position data is returned through digital servo feedback (DSF) together with an integrated multiturn absolute encoder, giving the drive controller position information over multiple revolutions. Power and signal conductors enter on side B through a sealed connector interface, which helps simplify cable routing in compact machine layouts. The motor uses a plain shaft and a standard shaft end without a second projection on the non-drive end, which helps keep inertia lower. It has length code B, which provides an active stack length that balances torque density and rotor inertia.

Mechanical alignment is supported by a centering diameter of 130 mm, enabling accurate concentric mounting without additional sleeves. The motor is assembled with a shaft seal, which helps protect internal parts from lubricant splash and axial contamination. It is supplied without a blocking brake, so holding torque during power-off conditions must come from the drive or an external clamp. The frame size is 093, which fits machines built around this mounting pattern and dimensional class.
