MDD025A-N-100-N2K-040PC1
The MDD025A-N-100-N2K-040PC1 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a motor for use with digital drive controllers and is designed to supply rapid rotary motion in compact automation axes. Within the series, it uses the 025 frame class and an A-length housing, which gives it a small footprint for high-speed positioning tasks. Integrated motor feedback supplies position data to the drive for closed-loop control, while a built-in blocking brake secures the shaft whenever power is removed in vertical or indexing machinery.
The motor develops a continuous standstill torque of 0.33 Nm, which indicates the load it can hold indefinitely without overheating when the rotor is locked. Maximum running velocity reaches 10000 rpm, allowing fast cycle times where throughput is critical. A blocking brake generates 1.0 Nm of holding torque to prevent drift during stops. For mechanical centering, the front flange features a 40 mm pilot diameter, letting the housing align precisely against gearboxes or mounts. All electrical and feedback conductors exit on Side A, which can simplify cable routing when multiple axes share the same direction. Standard balancing limits residual vibration, and the shaft seal helps keep lubrication in while excluding dust or coolant.
Cabling is handled through a connecting cable with coupling unit, which provides a dedicated interface for the motor wiring. Motion feedback is supplied by resolver feedback, a technology that tolerates electrical noise while still reporting angular position to the drive. The single shaft end uses a keyway for slip-free torque transfer, and no secondary shaft is provided on side B, which reduces overall length. A dedicated FPM seal protects that end from splash ingress. The compact 025 frame, combined with the A-length body and standard housing, keeps mass and inertia low and helps shorten settling times after rapid acceleration.
