Product Description:

The MDD071C-N-030-N2T-095PA0 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for direct pairing with digital drive controllers, the unit provides controlled rotary motion in automated machining, handling, and assembly stations. It translates commanded current from the inverter into mechanical rotation for axes that demand accurate positioning and repeatable speed profiles. This layout suits production equipment that runs repeated motion cycles throughout normal operation.

At standstill, the rotor develops a continuous torque of 6.6 Nm, giving the drive stable low-speed holding capacity without overheating. When energized by the matched inverter, the motor reaches a nominal speed of 3000 rpm, which suits feed axes and moderate-inertia spindles. A centering shoulder diameter of 95 mm aligns the flange to adjoining frames, while standard dynamic balancing keeps vibration within ISO limits for the 071 frame size. Power and feedback conductors are routed through a single connector on Side A, which helps reduce cable loops inside enclosures. Closed-loop regulation is enabled by the built-in digital servo feedback interface, which sends position data directly to the controller. The C length code gives the motor an extended stator stack depth, and the standard housing remains unventilated so cooling relies on surface conduction.

An integrated multiturn absolute encoder counts revolutions across power cycles, so the axis can retain position information after shutdown. The shaft connection uses a keyed profile to transmit torque, and the single-ended design comes without a side-B extension, which simplifies gearbox mounting. A factory-installed shaft seal blocks dust and coolant from entering the bearing cavity. Because this configuration ships without a blocking brake, any vertical load must be secured externally when power is removed. This layout suits timing-belt or hub drives where a sealed front bearing area is preferred.
