Product Description:

The MDD093C-N-040-N2M-130GA2 is a synchronous servo motor built by Bosch Rexroth Indramat for use with digital drive controllers in automated machinery. As part of the MDD Synchronous Motors series, the unit converts electrical energy from its drive into precise rotary motion for coordinated positioning and speed control on packaging lines, handling gantries, and similar systems. The motor is intended for closed-loop applications where the controller continuously corrects position and speed errors during operation. Its servo design supports synchronized motion on axes that must start, stop, and reverse with consistent response. Power and sensor leads leave the housing on Side A, which helps reduce cable loops when the motor is mounted near a cabinet wall.

The motor’s nominal running speed reaches 4000 rpm, enabling rapid indexing cycles while maintaining servo accuracy. A centering flange with a diameter of 130 mm helps align the motor with gearboxes or driven shafts, and it supports concentric mounting at the machine interface. During power-off conditions, a blocking brake provides 22 Nm of holding torque so vertical axes can remain stationary without external clamps. The output uses a plain shaft for direct coupling, and a shaft seal helps protect the interior bearings from dust or coolant spray. The plain shaft is suited to coupling arrangements that do not require a keyed connection.

Position data is captured by an onboard integrated multiturn absolute encoder, so the drive can retain absolute position information across multiple revolutions. The controller receives speed and commutation signals through digital servo feedback (DSF), supporting closed-loop motor control during dynamic motion. Because the encoder is absolute, the axis can return to controlled operation after power is restored without relying on an incremental reference count. The frame uses motor size 093, which provides a compact housing for multi-axis layouts, and standard dynamic balancing helps keep vibration low during operation. Low vibration also helps maintain stable feedback quality at higher shaft speeds.
