Product Description:

The MDD090B-N-020-N2L-130PR1 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into rotary motion so automated axes can follow precise speed or position profiles in machining centers, packaging equipment, and material-handling systems. The motor is supplied with a blocking brake and integral feedback so the drive can hold position and monitor rotor movement accurately during operation.

A centering pilot of 130 mm aligns the housing to the machine frame and helps reduce radial runout. Power and feedback plugs exit on the right side, allowing cleaner cable routing in compact machine layouts. A molded connector is used instead of loose terminals, which helps maintain shielding continuity and keeps wiring more secure. Continuous torque at standstill is rated at 7.2 Nm, which supports load holding while the speed loop remains closed. During operation, the rotor reaches a nominal speed of 2000 rpm. The motor size is 090, which corresponds to this frame format and mounting pattern. Standard balancing keeps vibration within normal limits, and the B length code indicates an intermediate active core depth for moderate inertia.

The blocking brake provides 6.5 Nm of holding torque so vertical axes remain locked when the controller is de-energized. Position data is returned through digital servo feedback, allowing the drive to determine commutation angle without auxiliary sensors. The output shaft uses a keyway to couple hubs or pulleys without slip, and it includes a shaft seal that helps prevent lubricant from migrating toward the encoder cavity. The standard shaft end leaves side B closed, while the aluminum housing supports heat transfer to the machine plate and preserves enclosure protection.
