MDD071A-N-030-N2S-095PA1
The MDD071A-N-030-N2S-095PA1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it provides closed-loop torque and speed control in packaging stations, pick-and-place axes, and light-duty tooling heads. The integrated blocking brake helps the axis remain in place when power is removed, while the single-ended shaft and standard housing keep the motor compact. Its synchronous design also supports predictable response to current commands, which helps maintain smooth motion during indexing and short travel cycles.
This model can deliver a continuous standstill torque of 2.2 Nm, which suits low-inertia loads that need steady holding force without excessive heat buildup. During dynamic operation, the rotor reaches a nominal speed of 3000 rpm, matching common servo applications that require fast and stable motion. The blocking brake provides 3.0 Nm of holding torque, helping suspended or vertical loads remain fixed after stopping. Mechanical centering uses a 95 mm locating diameter, which helps the motor align accurately on gearbox or machine mounting surfaces. Position and velocity signals are returned through digital servo feedback, allowing the controller to maintain precise closed-loop regulation without a separate external encoder. The motor has a size 071 frame, which keeps the package compact while supporting moderate power density.
Cables exit toward the drive because the power and feedback connections are on Side A, which supports clean cable routing in confined machine layouts. The assembly also includes a shaft seal at the output end to help reduce the entry of dust or coolant. Torque is transmitted through a keyway, allowing pulleys or couplings to mount without custom hubs. The motor uses length code A, making it the shortest version in its family, and it comes without a second shaft end to save space behind the mounting face. A rotor built to a standard balancing grade also helps the motor run smoothly at operating speed.
