MDD025A-N-100-N2G-040PD0
The MDD025A-N-100-N2G-040PD0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for compact tooling axes and pick-and-place stations. That makes it suitable for small automation equipment that needs repeatable positioning without a large motor footprint. It is intended for compact motion tasks that still demand stable speed control during short, repetitive cycles. The design follows the standard housing and balancing classes used in this motor line, so it fits directly into applications where high spindle speeds are required.
This model attains a nominal speed of 10000 rpm, allowing rapid cycle times when paired with compatible drives. At standstill, it can deliver 0.33 Nm of continuous torque for lightweight positioning stages. Accurate rotor position is returned through resolver feedback, enabling closed-loop control without an added digital encoder. Precise shaft alignment is supported by the 40 mm centering diameter, while an internal shaft seal helps keep contaminants out of the bearing set. Power and feedback conductors exit on side B of the frame through a connecting cable that terminates in a coupling unit, which helps keep wiring orderly in compact installations.
The unit is supplied without a blocking brake, so any static holding requirement must be met by the drive or external mechanics. The motor has size code 025 and length code A, giving it a short stack that helps reduce inertia during acceleration. It uses a keyway shaft to transmit torque to pulleys or couplings without relying on friction alone. The standard shaft end is closed, which helps keep the overall length compact. This layout is useful on small axes where installation space is limited and the motor must fit close to adjacent machine parts.
