Product Description:

The MDD093B-N-040-N2M-110GA2 is a permanent-magnet synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, allowing a closed-loop drive to regulate torque and speed in automated pick-and-place units, conveyors, and machine tool axes. The integrated multiturn absolute encoder returns position data to the controller during startup and operation. An internal blocking brake secures the load when power is removed, making the unit suitable for vertical axes and other applications that must hold position at standstill.

The motor can deliver a continuous standstill torque of 14.5 Nm, providing the static force needed to hold loads without overheating. Under rated excitation, it reaches a nominal mechanical speed of 4000 rpm, supporting fast cycle times in indexing or spindle applications. For short intervals, the holding brake supplies up to 22 Nm of brake torque to resist back-driving when the axis is idle. Dynamic balance uses the standard grade to help limit vibration across the speed range, and a standard housing encloses the stator windings. Power, feedback, and brake wiring enter on side A, and the single-piece motor plug uses a keyed connector for straightforward cable attachment.

Mechanical alignment to the machine face is handled by a centering pilot of 110 mm, which keeps the flange concentric with the motion axis during installation. Position data reaches the drive through digital servo feedback (DSF), allowing high-resolution velocity control without separate sensors. The length designation B indicates the stack length used for this frame size. A shaft seal is fitted to block coolant or oil ingress, and the single-ended plain shaft can be coupled to gearwheels, pulleys, or direct-drive bellows couplings. The 093 size code corresponds to the frame diameter and mounting pattern used for this motor.
