MDD025A-N-100-N2G-040PC1
The MDD025A-N-100-N2G-040PC1 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as an electromechanical actuator in digital drive systems, converting current commands into high-speed rotation for compact handling modules and test equipment. Its construction follows the series conventions for size 025 hardware, uses a standard housing with length code A, and includes the components needed for closed-loop operation within tight installation spaces. This arrangement supports precise motion in small automation assemblies where installation depth and motor diameter are limited.
At standstill, the rotor can generate continuous torque of 0.33 Nm, allowing the axis to resist light process loads without overheating. Once energized, the shaft reaches a nominal speed of 10,000 rpm, a value suited for rapid indexing where short cycle times are important. A blocking brake is integrated and supplies a static holding capacity of 1.0 Nm, which keeps the axis fixed whenever the drive is disabled. Electrical and feedback cabling exit on Side A, and power is routed through a connecting cable with a coupling unit, which helps keep cable routing orderly in multi-axis machines. The combination of high speed and modest continuous torque makes the motor suitable for light loads that need fast acceleration and repeatable stopping behavior.
The mounting face includes a concentric register of 40 mm, which aids quick alignment while standard balancing helps limit vibration at full speed. A tapered bore houses a shaft with a hardened keyway, ensuring positive torque transfer into gearboxes or pulleys. Because the output end is prepared for keyed transmission, the motor can drive pulleys, couplings, or compact gear stages without relying only on friction-based clamping. The shaft end follows the standard series layout without a side-B extension, which helps minimize overhang loads. The motor is supplied with a shaft seal, which helps prevent lubricant migration and fine dust ingress at the output end. Position data are returned through resolver feedback, enabling the drive controller to close current, velocity, and position loops across the full operating range.
