Product Description:

The MDD025A-N-100-N2G-040PL1 is a small-frame synchronous servo unit produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it delivers rapid position and velocity control on compact automation axes where cycle time is critical. This model supplies torque directly to the load through its keyway shaft and includes an internal blocking brake that secures the rotor when power is removed, making it suitable for vertical axes and other compact motion applications that require controlled stopping.

The motor generates a continuous standstill torque of 0.33 Nm, giving steady low-speed holding force for precision indexing tables and small pick-and-place heads. During operation, it can reach a nominal speed of 10,000 rpm, which allows high linear throughput when coupled with appropriate gearing. An integrated brake delivers 1.0 Nm of static torque to help prevent back-driving without external clamps. Mechanical alignment is aided by a centering diameter of 40 mm, so mounting plates can locate the motor concentrically. The size code is 025, which indicates the compact frame used for this motor. Balancing, housing style, and shaft end use the standard MDD configuration found across this motor platform.

Cabling enters from the left side, and this left-hand connection direction keeps power and feedback conductors clear of adjacent drive components in tight panels. A factory-installed shaft seal helps block coolant or dust from migrating along the output shaft during operation. Rotor position is reported through resolver feedback, so compatible drives can close the servo loop without additional interpolation electronics. Power is transmitted through a single-piece output shaft that uses a keyway to secure pulleys or couplings, and the motor's length code A marks the shortest stack height available in this family.
