Product Description:
The MDD115A-F-015-R2L-180GA2 is a synchronous AC servo motor built by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current from the drive into regulated torque and speed for axis modules, material handling stations, and other automated motion systems. The motor supports closed-loop operation through an integrated position transducer, allowing the drive to maintain accurate speed and position under changing mechanical loads. Because the control loop remains active during operation, the unit can support repeatable starts, stops, and direction changes in machinery that depends on precise rotary motion.
At standstill, the motor delivers a continuous torque of 28.0 Nm, giving the axis steady holding force during low-speed or stationary operation without excessive thermal stress. During motion, it reaches a nominal mechanical speed of 1500 rpm, which fits medium-speed production lines driven by compatible Indramat digital drives. The housing is prepared for liquid cooling, so waste heat can be removed through an external coolant circuit when the application has a demanding duty cycle. Rotor position is reported through digital servo feedback, which supports drive-based commutation and precise speed regulation across the operating range. All power and feedback connections face Side A of the flange, and the mounting pilot has a diameter of 180 mm for accurate centering against machine plates or gearbox interfaces.
Mechanical restraint is provided by an integrated holding brake that develops 60.0 Nm of static torque, allowing vertical or suspended axes to remain secured when drive power is removed. The output shaft is a plain shaft with a shaft seal, which helps limit lubricant migration and reduce dust entry at the rotary interface. Dynamic balance grade R reduces residual vibration at rated speed and supports smoother rotation in assemblies that depend on precise shaft alignment. These features suit applications where stable positioning and consistent running behavior are required throughout normal machine cycles.
