Product Description:

The MDD093A-N-040-N2L-130GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the mechanical actuator in closed-loop drive systems that use digital controllers. The motor converts commanded current into precise rotary motion for industrial positioning and velocity control tasks such as packaging axes, tool changers, and pick-and-place gantries, where repeatable response is required during frequent starts and stops.

This model reaches a nominal speed of 4000 rpm, allowing fast cycle execution when the drive delivers rated voltage and frequency. At standstill, it can supply 9.2 Nm of continuous torque, giving machines sufficient holding force without overheating during dwell periods. An integrated blocking brake supplies an additional 11 Nm of holding torque so vertical loads remain stationary when power is removed. Mechanical centering during mounting is guided by a 130 mm centering diameter, which helps align the stator housing to the machine frame and reduce runout. Rotor position is returned to the controller through digital servo feedback, enabling high-resolution commutation and diagnostic functions. Power and feedback conductors exit through a right-oriented connector, simplifying cable routing inside compact enclosures.

The motor uses a dynamically balanced rotor classified as standard, and the housing is also standard for general industrial installations. A plain shaft is supplied for backlash-free coupling to gears or pulleys, and a factory-installed shaft seal helps protect the front bearing against coolant or dust ingress. The frame is identified by size code 093, indicating the stator lamination diameter used for this motor platform. With motor length code A and no secondary shaft end, the unit fits shallow installations and leaves more room for couplings and cable bends in compact assemblies.
