Product Description:

Bosch Rexroth Indramat builds the MDD065B-N-040-N2L-095PB1 for use in the MDD Synchronous Motors series. This motor functions as a drive element for digital controllers, supplying rotary motion wherever closed-loop positioning is needed. Within an automation line, it couples directly to a mechanical load, converting commanded current into torque while sending position data back through its integrated encoder. Its compact form suits light tooling axes, transfer devices, and conveyor stations where short motor length helps preserve installation space. Its feedback path allows the controller to correct position error during acceleration, deceleration, and short dwell periods.

The motor face includes a centering pilot of 95 mm, allowing repeatable alignment to gearboxes or machine flanges without shims. Power and feedback cables exit on Side B through a keyed connector, which helps keep cable runs directed away from the driven load in tight enclosures. Encoder information is produced by digital servo feedback (DSF), supplying absolute position data for the controller and supporting precise commutation after startup. Under continuous stall conditions, the rotor delivers 1.5 Nm, and it can be driven up to a nominal speed of 4000 rpm for fast indexing routines. Standard dynamic balancing reduces vibration, and the housing uses unventilated construction for applications that rely on passive heat dissipation. This arrangement is useful on compact axes where nearby guards or machine panels leave little room for cable bends.

In stop mode, a blocking brake rated at 3.0 Nm secures the load and releases automatically when current is applied. The single shaft end is machined with a keyway for positive torque transmission, and the front bearing region is protected by a shaft seal to help limit lubricant migration into the motor. Frame size 065 uses a compact housing that is well suited to synchronized multi-axis assemblies with limited mounting space. A sealed front end also helps when the motor operates near light dust or occasional splash from adjacent machine components. The standard mechanical housing and the absence of a rear shaft extension simplify installation where couplings, pulleys, or small gear units must fit close to the motor face.
