Product Description:

The MDD093B-N-040-N2L-110GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into precise rotary motion for positioning axes, feeders, and similar automation tasks. This makes the unit suitable for machines that require repeatable motion and fast response to changing commands. The motor uses a standard housing and internal balancing that meets ISO class G requirements, which helps support smooth operation during repeated starts, stops, and reversals.

This model reaches a nominal speed of 4000 rpm, allowing high throughput in cycle-dependent machinery. A continuous standstill torque of 14.5 Nm keeps loads stable while the shaft is at zero speed, which is useful during dwell periods in pick-and-place equipment. The centering recess measures 110 mm, helping the motor align accurately with common mounting flanges. Electrical power and feedback cables exit on Side B through a sealed connector, which supports orderly routing and quick connection changes. Placing the cable outlet at the rear also keeps the mounting face clear for coupling and installation access. Rotor position is reported through digital servo feedback (DSF), giving the controller the information needed for accurate speed and torque regulation.

For static holding or use on vertical axes, the motor includes a blocking brake rated at 22 Nm, which provides mechanical holding force when power is removed. Torque is transmitted through a plain shaft, and a shaft seal helps protect the front bearing from coolant splash and fine dust. The shaft is provided only on the drive end, so couplings mount on one side of the motor. Size 093 with length code B gives the motor the stack length and frame proportions associated with this housing. The standard housing finish suits general-purpose industrial enclosures, and the balanced rotor helps limit residual vibration during rapid direction changes.
