Product Description:

Bosch Rexroth Indramat manufactures the MDD093A-N-040-N2M-130GL1 as part of the MDD Synchronous Motors series. The unit operates as a motor for digital drive controllers, converting controlled three-phase electrical energy into mechanical rotation for positioning, feed, and auxiliary axes in industrial automation equipment. It uses a permanent-magnet rotor with electronic commutation to provide steady torque over a wide speed range. This arrangement supports accurate synchronization with drive commands in machining centers, printing lines, material-handling systems, and other automated equipment. It is suited to applications that need repeatable speed control and stable positional response during frequent start-stop cycles.

At standstill, the motor can deliver 9.2 Nm of continuous torque, which lets an axis hold load without overheating during sustained operation. Under electronic commutation, the rotor reaches a nominal speed of 4000 rpm, allowing fast traverse motion before the machine shifts to feed movement. A centering shoulder of 130 mm helps align the housing to the machine frame, and the integrated blocking brake supplies 11 Nm of holding torque to resist back-driving during power loss. Position data is returned through digital servo feedback, so the controller can maintain closed-loop regulation of speed and position.

Power and feedback cables exit on the Left side through a keyed Connector, which helps organize wiring where installation space is limited. The output element is a plain shaft that accepts standard couplings, and a fitted shaft seal helps protect the internal bearings from coolant spray while limiting lubricant escape. Standard dynamic balancing reduces vibration during operation. The A length code gives the motor a shorter housing, which suits linear axes that need moderate inertia and a compact installation depth.
