Product Description:

The MDD093A-N-040-N2L-130GR0 is a synchronous AC motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for pairing with digital drive controllers where accurate, closed-loop position and velocity regulation are required in assembly lines, packaging machinery, and gantry axes. By converting commanded current into proportional torque, the unit acts as the electromechanical interface between the controller and the driven load, providing responsive motion in repetitive industrial duty cycles. Its synchronous design helps the drive maintain accurate rotor alignment during indexing, speed changes, and repeated start-stop operation.

At standstill, the motor delivers 9.2 Nm of continuous torque, giving process stations enough holding force without thermal overload. During motion, it sustains a 4000 rpm nominal speed, so linear conveyor segments can be indexed quickly while maintaining servo accuracy. A 130 mm centering diameter is machined into the flange to guide the motor into pilot recesses and maintain shaft alignment with the driven equipment. Size code 093 specifies a moderate stator diameter, and length code A indicates the shortest stack in the family. This combination keeps rotor inertia relatively low and supports quick reversals on compact servo axes. Standard balancing limits vibration, and the housing is prepared for use with digital servo feedback.

The power and feedback conductors exit on the right side through a keyed connector, which helps route cables away from neighboring machine parts. A radial shaft seal is fitted to block coolant spray and airborne particles from entering the bearing chamber, and the motor uses a single plain shaft for direct coupling to pulleys or rigid hubs. Because the motor is supplied without a blocking brake, external clamping or drive-generated holding torque must keep the load in place when power is removed. The shaft is provided on side A only, which keeps the mechanical layout simple and leaves the non-drive end free of an additional output extension.
