Product Description:

The MDD093C-N-020-N2M-110PL0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It serves as an electromechanical actuator for digital drive controllers, converting current commands into regulated rotary motion for positioning and indexing functions in automated equipment. The motor is suited for closed-loop axes where repeatable speed and position control are required during machine operation. Its synchronous design supports accurate torque response during starts, stops, and short motion segments. It is commonly used on feed axes, indexing tables, and handling systems.

Its mechanical interface uses a centering pilot of 110 mm, allowing repeatable alignment between the motor flange and the machine face. Power and feedback conductors exit on the left side, and a single connector plug simplifies cable attachment. Position data are supplied by the factory-installed integrated multiturn absolute encoder, so the drive controller retains shaft position information after power loss. During continuous operation, the rotor is rated for a nominal speed of 2000 rpm, suiting applications that favor high torque at moderate speed. Standard dynamic balancing limits vibration, and the C length code extends the active stack compared with shorter versions, adding magnetic section within the 093 frame.

Because the motor is supplied without a blocking brake, stopping torque must be generated by the controller or by external mechanics. Command loops rely on digital servo feedback (DSF), which transmits high-resolution encoder data to the drive over a noise-immune serial channel. A hardened shaft with a keyway couples torque to pulleys or couplings, and the front bearing area is protected by a design that ships with a shaft seal to retain lubricants and exclude contaminants. The standard housing dissipates heat by natural convection, and the omission of a side-B shaft end reduces overhung mass for compact installations. This layout also leaves more room around the motor where a rear shaft extension is not required.
