Product Description:

The MDD093B-N-040-N2L-110PA2 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it serves in industrial automation systems that require fast point-to-point moves and stable velocity regulation. By pairing the rotor's permanent-magnet field with drive-generated stator current, the unit delivers tightly controlled torque to conveyors, pick-and-place heads, and auxiliary spindles in manufacturing and material-handling equipment. This operating principle supports quick response to command changes and steady motion across repeated start-stop cycles. It also supports stable speed control when the driven load varies through the machine cycle.

During operation the motor can reach a nominal speed of 4000 rpm, which suits high-cycle positioning tasks. At standstill it sustains a continuous torque of 14.5 Nm, so the motor can hold load without overheating under rated conditions. For short braking or start-up events, an integrated blocking brake provides 22 Nm of holding torque. Rotor position is reported through digital servo feedback (DSF), enabling the controller to close the current, velocity, and position loops in real time. Power is transferred through a keyway shaft, which helps keep the driven hub engaged during repetitive acceleration and deceleration.

A centering diameter of 110 mm aligns the motor accurately on the machine plate. Connections exit on side A through a compact connector, which helps keep the cable path orderly near the mounting face and supports straightforward routing toward the drive cabinet. The front end uses a standard shaft without a side-B extension and is fitted with a shaft seal to limit lubricant egress during rapid speed reversals. The housing and balancing are standard, while the 093 size and B length place the unit in a medium frame suited to general servo duty.
