Product Description:

The MDD093B-N-020-N2L-110PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into precise rotary motion for positioning, feed, and handling axes in automated machinery. Its electromagnetic layout, encoder interface, and integrated brake support smooth acceleration, controlled stopping, and accurate rotor position reporting during closed-loop operation. This motor type is commonly used on CNC axes, packaging equipment, and transfer systems where repeatable motion is required. Because feedback is integrated in the motor, the drive can monitor rotor movement directly instead of relying on external sensing hardware.

At standstill, the motor can sustain a continuous stall torque of 14.5 Nm, which indicates the load it can support continuously without thermal overload. The nominal rotational speed is 2000 rpm, giving the drive a practical operating point for common servo applications. A built-in digital servo feedback (DSF) encoder relays position data to the controller, allowing fast correction of speed and position deviations. During shutdown, the blocking brake provides 11 Nm of holding torque so vertical or suspended loads can remain stationary. A centering diameter of 110 mm helps align the motor with standard machine flanges and supports accurate shaft positioning at the mounting face.

Power and feedback cables exit on the A-side, which can simplify routing toward cabinet raceways in many machine layouts and keep cable bends more orderly near the motor. The output uses a keyway shaft for positive torque transmission with keyed couplings or pulleys. The motor has frame length B, matching the medium 093 frame configuration used for this housing size. An internal shaft seal behind the front bearing helps limit lubricant loss and reduce the entry of dust or coolant. The housing uses the standard cast style, dynamic balancing reduces residual vibration, and the shaft is single-ended so the non-drive side stays clear in tight mounting spaces. That arrangement is useful when the rear of the motor must sit close to guards, machine frames, or adjacent components.
