MDD065B-N-040-N2L-095GR0
The MDD065B-N-040-N2L-095GR0 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for digital drive controllers in industrial automation, the unit supplies controlled rotary motion so positioning tables, feeders, and small spindles can operate with repeatable velocity and torque. It is suited to compact servo axes that require stable response during frequent starts, stops, and short positioning moves. Its electromechanical layout supports close integration with matched drive components.
At standstill, the motor can supply a continuous torque of 1.5 Nm, allowing closed-loop drives to hold a load without overheating. During motion, its rated operating point reaches a nominal speed of 4000 rpm, a value suited to compact inverters used in packaging or textile equipment. Rotor position is returned through digital servo feedback (DSF), enabling high-bandwidth current and velocity loops. Accurate mechanical mounting is supported by a centering shoulder of 95 mm. Dynamic balance is specified as standard quality, and both power and feedback connections exit on the right side of the housing for straightforward cable routing. The motor uses a standard cast-aluminum frame, has length code B, and has a single-sided shaft configuration without an extension on side B.
System interfaces are protected by a shaft seal that helps keep lubricants and airborne debris away from the front bearing. The unit is supplied without a blocking brake, so holding torque must be provided by the controller or an external mechanism when the axis is stopped. Its frame is size 065, which gives the motor moderate rotor inertia for fast acceleration on small to medium axes. Output torque is delivered through a plain shaft that can be paired with keyed or clamping couplings. Electrical connection is made through a single multipole connector, allowing the motor to be disconnected without disturbing the mounting hardware. The electrical constants are optimized for pulse-width-modulated supplies used with digital drive controllers rather than for direct line power.
