Product Description:

The MDD025A-N-100-N2K-040MB0 is a compact synchronous motor from Bosch Rexroth Indramat's MDD Synchronous Motors series. It is intended for use with digital drive controllers and is sized for light-duty axes in compact automation equipment that require fast positioning and speed control in automated assembly, electronics mounting, or small gantry stages. When paired with a compatible drive, the motor converts commanded current into mechanical motion and maintains precise velocity in closed-loop servo systems. This operating role makes it suitable for applications where quick response and repeatable movement are more important than high continuous torque.

The motor's nominal speed reaches 10000 rpm, enabling short cycle times in applications that demand rapid acceleration. At standstill, it can supply 0.33 Nm of continuous torque, so modest holding force is available without overheating. Accurate mechanical alignment is supported by a 40 mm centering diameter that matches common flange interfaces. Power and feedback conductors exit on side B of the housing, and they terminate through a single connector that seals against the case. Standard dynamic balancing helps limit shaft vibration at high speed, and this arrangement supports compact installation in tightly spaced machine sections.

Signal resolution is provided by an integrated absolute encoder, while primary position feedback to the drive is handled through resolver feedback. The output shaft has a keyway for slip-free coupling, and the motor has no shaft seal, so it should be used where liquid ingress is not expected. The motor uses size code 025 with length code A and has a standard single-ended shaft on the drive side only. Because it is delivered without a blocking brake, static load holding must be supplied by the drive or by external machine mechanics.
