Product Description:

The MDD071A-N-030-NZS-095GA1 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied for use with digital drive controllers in closed-loop motion systems. In industrial automation, it converts commanded current into precise rotary motion for indexers, pick-and-place units, and other controlled axes that require repeatable positioning and stable speed control. This motor type is suited to compact machine axes where accurate starts, stops, and speed changes are required throughout normal operation.

Its nominal operating speed reaches 3000 rpm, which is the top synchronous speed at rated voltage. At standstill, the electromagnetic system can deliver a continuous torque of 2.2 Nm, allowing the motor to hold a steady load without overheating during continuous operation. A blocking brake is integrated with a static holding capacity of 3.0 Nm, so the shaft can remain locked when drive power is removed. Rotor balance is standard for general-purpose machinery. The centering shoulder has a diameter of 95 mm, which helps align the housing in mounting fixtures. The motor uses size code 071 with length code A, giving it a compact form for light to medium-duty stations. The housing uses the standard design, so no additional surface cooling devices are fitted.

The electrical interface is arranged on the machine side. Power and feedback cables exit on Side A and terminate through a sealed Connector, which helps keep wiring compact and protected at the motor. Position information is returned by the integrated digital servo feedback (DSF), providing high-resolution signals for drive-based current and velocity loops. The output element is a plain shaft fitted with a shaft seal, which helps limit lubricant loss and contaminant ingress while allowing the use of custom couplings without keys. The plain shaft is intended for applications that use custom couplings instead of keyed hubs.
