MDD065B-N-040-N2L-095PR1
The MDD065B-N-040-N2L-095PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it translates drive current into controlled rotary motion for positioning axes, conveyor spindles, and pick-and-place actuators. This operating style makes it suitable for closed-loop motion tasks that require repeatable speed and position control. The 065 frame size and B length code give the motor a narrow stator stack that fits confined machine spaces while still supporting mid-range torque. Its shaft end is supplied in the standard style without a side-B extension, so couplings can be installed without additional shaft hardware.
The rotor uses standard balancing to limit dynamic forces during acceleration. A centering register of 95 mm aligns the motor on the machine frame and provides a consistent reference for concentricity. Power and feedback leads exit to the right-hand side, and the motor uses a single connector for simpler cable routing. The right-side cable exit can help when the motor is mounted in narrow machine bays. At standstill, the stator can deliver 1.5 Nm of continuous torque, and the winding supports a nominal operating speed of 4000 rpm. Closed-loop regulation is achieved through digital servo feedback, which returns high-resolution position data to the drive.
For axis safety, the motor is delivered with a blocking brake that applies 3.0 Nm of holding torque when power is removed, allowing vertical loads to remain stationary without external clamps. The drive-side shaft uses a keyway to transmit torque through standard keyed couplings, and a fitted shaft seal helps prevent lubricant or coolant ingress along the journal. A standard housing encloses the laminated core and winding set while keeping mounting geometry consistent across the series. The housing also provides a rigid outer structure for the stator assembly and connection area. The brake and shaft sealing support axes that must hold position at rest and operate near coolant or lubricant exposure.
