Product Description:

The MDD090B-N-020-N2L-110GR0 is a brushless AC servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled electrical power into precise rotary motion for tooling, conveyors, and packaging axes in automated equipment. Its closed-loop servo design supports repeatable positioning and steady speed control during normal production cycles. It is suited for synchronized axes that must respond quickly to command changes while maintaining stable motion through repeated start-and-stop sequences.

At a nominal speed of 2000 rpm, the rotor maintains synchronized rotation under rated load. A continuous standstill torque of 7.2 Nm allows the axis to hold static loads during dwell periods without overheating. Precise velocity control is supplied through digital servo feedback (DSF), allowing the controller to monitor rotor position with high resolution. The motor has an MDD size 090 frame and length code B, which gives a compact profile while preserving thermal mass, and radial alignment is supported by a 110 mm centering pilot. Output torque is transmitted through a plain shaft, and a shaft seal is fitted to restrict lubricant migration toward the motor interior.

Electrical terminations use a connector that simplifies cable replacement and follows the series pin layout. The power and feedback plugs are oriented on the right side of the end bell, which helps clear vertical mounting rails and keeps bend radii inside the cabinet. Because the unit is supplied without a blocking brake, any load-holding requirement must be provided by the drive or by an external mechanical lock. The shaft is present only on the drive side, which eliminates side B overhang mass and suits installations that need clean surfaces and moderate inertial loads. This layout also keeps cable routing orderly in compact machine sections.
