Product Description:

The MDD025A-N-100-N2K-040MA0 is a brushless synchronous motor from the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a motor for digital drive controllers, it supplies regulated rotary power for packaging machines, semiconductor tools, and small assembly stations. Its compact format suits multi-axis equipment where fast motion, low moving mass, and accurate servo control are required. Because it is a brushless motor, there are no brushes to wear during normal servo operation. The design can replace stepper or pneumatic actuators in applications that need repeatable positioning in a small installation space.

A centering diameter of 40 mm aligns the flange with the machine face, and power and feedback leads exit on Side A for straightforward cable routing in tight spaces. The motor uses a circular connector, so the electrical interface remains enclosed and easy to connect. At standstill, it can deliver 0.33 Nm of continuous torque, which suits low-inertia indexers and other small positioning axes. The rotor and stator are balanced to the standard grade to help keep vibration low at higher shaft speeds. The shaft runs without a shaft seal or a second shaft end, which reduces friction and leaves the non-drive side closed.

Position data is provided through resolver feedback, allowing the drive to monitor rotor angle during acceleration and steady operation. The motor uses frame size 025 and reaches a rated speed of 10000 rpm, giving a light assembly that can be direct-coupled to compact spindles or small motion stages. The short A length helps the motor fit compact slides and dispensing heads where installation depth is limited. Power is transmitted through a keyway on the shaft for positive coupling to pulleys or hubs. The unit is supplied without a blocking brake, so holding torque must be provided by the drive or by external mechanical hardware when the axis is stopped.
