Product Description:

The MDD093A-N-040-N2M-130GB2 synchronous motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit acts as a closed-loop actuator in machinery that requires rapid, repeatable motion such as pick-and-place systems, tool spindles, and feeder axes. By converting inverter-supplied current into rotary motion, it delivers programmable speed and torque for automated production tasks.

At its nominal speed of 4000 rpm, the rotor remains synchronized with the supplied excitation frequency, supporting high feed rates without loss of accuracy. While motionless, the stator can provide 9.2 Nm of continuous torque, enabling the axis to support loads without overheating. A centering shoulder of 130 mm simplifies coaxial alignment during mounting. Power, brake, and feedback plugs are oriented on side B, so cable glands stay clear of adjacent mechanics. For vertical axes, the integrated brake supplies 22 Nm of holding torque that automatically clamps when power is removed. The housing follows the standard MDD form and connections are made through a molded connector set.

Closed-loop integrity is based on digital servo feedback (DSF), which transmits position and velocity data during each control cycle. An integrated multiturn absolute encoder tracks shaft angle across 4096 turns, eliminating the need for homing after shutdowns. Shaft contamination is limited by a shaft seal, and torque is delivered through a plain shaft that permits backlash-free clamping hubs. The motor uses length code A to keep overall depth low, has standard dynamic balancing to minimize residual vibration, and omits a rear shaft end so it can sit flush against gear reducers. Frame designation 093 sets the flange pattern for this motor size.
