Product Description:

The MDD065B-N-040-N2L-095GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit converts regulated electrical power into controlled rotary motion for positioning and velocity tasks in automated machinery. It is intended for axes that need repeatable speed control, responsive acceleration, and consistent stopping behavior in assembly cells, packaging equipment, and compact handling systems. This arrangement is commonly used where a motor must follow frequent command changes without losing positional consistency.

Its mechanical interface begins with a centering diameter of 95 mm, allowing precise alignment inside the machine frame. Power and feedback lines exit on side B, so the cable direction should be considered when the motor is mounted in tight spaces. At standstill, the motor can deliver 1.5 Nm of continuous torque, and a blocking brake supplies a holding torque of 3.0 Nm when power is removed. During operation, the rotor can reach a nominal speed of 4000 rpm, enabling rapid indexing cycles. Motion commands are closed through digital servo feedback, giving the drive the position information needed for accurate loop control. Standard balancing, a B-length frame, and a standard housing support stable operation while heat is dissipated through natural convection. The holding brake also helps keep the axis stationary after shutdown.

Size code 065 sets the stator diameter for this motor frame, while a plain shaft transfers torque through a friction-based coupling instead of a keyed connection. A removable field wiring connector simplifies attachment of the motor leads, and a fitted shaft seal helps keep dust or coolant away from the front bearing area. The smooth shaft can reduce backlash associated with keyed hubs when a proper clamping element is used. The non-drive-end shaft extension is omitted, which reduces overall length where space is limited. The motor is suited to compact installations that use compatible Rexroth power modules and require clean cable routing at the connection point.
