Product Description:

The MDD093D-N-040-N2L-130PL0 is a synchronous motor in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, the unit converts electrical power into mechanical torque for positioning, conveying, and indexing axes in industrial automation. Its commutation and feedback formats match compatible Rexroth drive families, allowing closed-loop motion control without additional interface hardware. This arrangement lets the controller regulate torque, speed, and position with direct feedback from the motor, which suits servo applications that need repeatable movement and steady response during changing loads.

The motor develops a continuous standstill torque of 24.0 Nm, allowing it to hold static loads without overheating when the shaft is locked. Its rated mechanical speed reaches 4000 rpm, which is the maximum synchronous velocity under nominal voltage and frequency. Accurate mechanical alignment is supported by a centering diameter of 130 mm on the mounting flange, which helps the motor seat correctly against mating machine surfaces. Power and encoder leads exit on the left, and Digital servo feedback (DSF) transmits rotor position to the controller for closed-loop velocity and position control. Standard rotor balancing helps reduce vibration during operation and supports smooth running at higher shaft speeds.

The motor uses a keyway shaft profile for positive torque transmission to pulleys or couplings, and a shaft seal limits the entry of dust or lubricant from adjacent components. Electrical terminations are made through a connector, which keeps the connection secure and simplifies cable removal without disturbing internal motor wiring. The motor is supplied without a blocking brake, so position must be maintained by external holding hardware or drive torque when power is removed. Length code D provides a longer active stack to support the higher torque rating, and the side-B shaft end is omitted to reduce the space needed in compact axis modules.
