Product Description:

The MDD093B-N-040-N2L-110GL2 is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for digital drive controllers and converts commanded current into precisely regulated torque and speed for machining centers, handling stations, and other coordinated axes in industrial automation. Its synchronous design supports accurate closed-loop motion, and standard rotor balancing helps reduce residual vibration during operation. It is commonly used where the drive must respond quickly to command changes without losing position accuracy.

At standstill, the rotor can deliver up to 14.5 Nm of continuous torque, allowing the axis to hold load without thermal overload. When motion is required, the winding geometry and magnet design support a nominal speed of 4000 rpm, giving the drive a broad velocity range for rapid positioning. This combination of zero-speed torque and nominal speed allows the same motor to support both holding and transfer tasks on the axis. An integrated blocking brake has a static holding torque of 22 Nm, which secures vertical or suspended loads when power is removed. Mechanical alignment to the machine frame is guided by a centering diameter of 110 mm, while position and velocity feedback are supplied through digital servo feedback (DSF) so the controller can close high-resolution motion loops.

Cabling enters from the left because the connection hardware is oriented on that side, and the power and encoder leads terminate through a connector for straightforward installation. The left-side cable orientation can help when machine layouts route motor wiring along one side of the axis. The motor uses size code 093 and length code B, which indicate its electromagnetic stack and overall depth within the series. A plain shaft is supplied, and the shaft has no second extension that could complicate coupling layouts. A shaft seal at the drive end helps limit the entry of contaminants and supports clean operation around the shaft interface.
