Product Description:

The MDD093A-N-020-N2M-130GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into precise rotary motion for positioning tasks in automated equipment. This type of motor is commonly used where the drive must maintain smooth response during repeated starts, stops, and short positioning moves. The 093 frame size with A length gives the unit a compact housing, while standard housing construction and standard rotor balancing support direct installation in typical machine layouts. Power and feedback leads exit on the right side, which helps route cables cleanly beside adjacent control hardware and reduces sharp bends near the motor.

The motor uses a centering diameter of 130 mm, providing a reference surface that aligns the mounting face with gearboxes or adapter plates. This centering feature also helps maintain consistent alignment between the motor shaft and the driven load, which reduces coupling stress. At standstill, it can deliver 9.2 Nm of continuous torque for holding force during low-speed or stationary operation. The rotor reaches a nominal speed of 2000 rpm, and closed-loop control is supported through digital servo feedback (DSF) for accurate speed and position monitoring. Electrical and signal conductors terminate on a connector, which provides a secure interface and helps preserve shielding integrity.

An integrated blocking brake provides 11 Nm of torque to hold vertical or suspended loads when power is removed. Position data is supplied by an integrated multi-turn absolute encoder, so the controller can retain axis position information after shutdowns. The brake and feedback package make the motor suitable for axes that must restart without a homing cycle after normal power loss. Torque is transmitted through a plain shaft, which is suited for clamping elements or shrink discs rather than keyed couplings. The drive end also includes a shaft seal, which helps limit contamination at the front bearing.
