Product Description:

The MDD090B-N-020-N2L-130GB2 is a synchronous AC servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for packaging equipment, transfer axes, and other automated machinery. The motor uses a standard housing with standard rotor balancing, which supports consistent mechanical integration in common machine layouts. This operating role suits axes that require accurate acceleration, deceleration, and stable motion during repeated production cycles. Its design supports repeatable torque delivery while the drive manages closed-loop speed and position control through the feedback system.

A centering diameter of 130 mm positions the motor accurately in the mounting interface and helps maintain shaft alignment at the coupling. The motor can produce a continuous standstill torque of 7.2 Nm, giving the axis holding capability during low-speed or stationary operation without excessive thermal stress. Its rated speed is 2000 rpm, which suits applications that need steady shaft velocity rather than very high spindle speed. Electrical connections leave from side B through a single connector, keeping power, brake, and feedback wiring grouped at one end of the motor.

An integrated blocking brake provides 11.0 Nm of holding torque so the shaft can remain secured when drive power is removed, and a shaft seal helps limit contamination at the output end. Position and speed signals are returned through digital servo feedback, allowing the controller to monitor rotor movement continuously during closed-loop operation. The motor uses motor size 090 with length code B, which gives it a compact housing for installations where space is limited. A plain shaft is used at the output, and the single-ended layout suits direct couplings or gearbox inputs that do not require an auxiliary output shaft.
