Product Description:

The MDD065A-N-060-N2L-095PR0 is a synchronous motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. In automated machinery, it converts commanded current from the drive into mechanical rotation, allowing coordinated axis motion over a wide speed range. This operating role supports precise speed control and repeatable positioning in machine axes that must react quickly to command changes. The design targets installations that need high spindle velocity and compact geometry while remaining compatible with the manufacturer's modular inverter families.

This model reaches a nominal speed of 6000 rpm, so the driven axis can execute rapid positioning cycles without gearing. At standstill, it supplies 0.8 Nm of continuous torque, which is the maximum continuous torque that can be applied at zero speed without overheating the windings. A centering diameter of 95 mm aligns the flange to precision mounting surfaces, and the power and feedback cables exit through a right-side connector to simplify cabinet routing. Feedback is handled by digital servo feedback; the encoder reports position to the drive for closed-loop control and eliminates a homing routine after power-up. The motor uses length code A, which indicates the shortest stator stack available in the 65 mm frame and helps reduce mass for low-inertia axes.

Standard dynamic balancing limits vibration during high-speed operation, and the standard housing withstands typical shop-floor contaminants. The output end has a shaft seal that helps prevent coolant or dust from entering the bearing chamber. Because the unit is supplied without a blocking brake, any holding function must be provided by the drive or external mechanics. The motor has a frame size of 065, and the single-ended shaft is machined with a keyway to secure pulleys or couplings. The shaft end on side B is omitted to save space behind the mounting plane in compact machine layouts.
