MDD071B-N-030-N2S-095GR1
The MDD071B-N-030-N2S-095GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for operation with digital drive controllers, this motor converts electrical energy into precisely regulated rotary motion for positioning tables, handling axes, and similar automation tasks. Its construction follows the series standard housing format and balancing class, allowing direct integration into equipment that demands continuous duty and rapid dynamic response. This type of motor is suited for applications that require repeatable motion, stable torque delivery, and responsive control during frequent start-stop cycles.
The motor is categorized as size 071, a frame designation that sets the external dimensions and mounting pattern. A centering diameter of 95 mm provides accurate shaft alignment with coupled loads, which helps reduce runout and vibration during operation. At standstill, it can supply a continuous torque of 4.4 Nm, allowing the drive to hold static loads without overheating. Under rated electrical frequency, the rotor reaches 3000 rpm, which suits applications that rely on high-speed cycles while maintaining servo accuracy. Power, brake, and feedback conductors terminate through a sealed connector, so the cable harness can be removed without opening the motor housing.
The built-in blocking brake develops 3.0 Nm of holding torque, so vertical or suspended axes remain locked when the controller is de-energized. Position information is returned through digital servo feedback, enabling the drive electronics to close high-resolution velocity and position loops. All connections emerge on the right side, which helps keep cabling consistent inside multi-axis cabinets. The front end is equipped with a shaft seal, which helps protect against oil ingress when the shaft passes through lubricated gearboxes. The motor also uses a plain shaft end and a standard housing for installation in tightly packed industrial assemblies.
