Product Description:

Bosch Rexroth Indramat's MDD090A-N-020-N2L-110PL2 belongs to the MDD Synchronous Motors series and is supplied for use with digital drive controllers in general-purpose automation. It is intended for closed-loop servo applications where commanded current is converted into controlled rotary motion. The unit is built on a 090 frame size with a standard housing. It uses internal rotor balancing, comes from the compact A length group, and combines integrated digital feedback, a keyed shaft, and an installed blocking brake to deliver position-controlled motion for axes that must hold load when power is removed.

The motor reaches a nominal speed of 2000 rpm, allowing the drive to synchronize cycles that demand moderate rotational velocity. At standstill, it develops 3.7 Nm of continuous torque, and this output reflects the winding design and cooling surface of the A-length housing. Power and feedback terminations exit on the left side, and the motor uses a connector interface that keeps the connection arrangement simple. This side-mounted layout can also help when cable runs must stay clear of couplings and other moving parts. Rotor position is reported by digital servo feedback, so the associated controller can close velocity and position loops without additional sensing hardware.

For static holding and emergency stops, the integrated brake supplies 11.0 Nm of torque, removing the need for external clamping devices on vertical or suspended loads. Mechanical alignment is aided by a centering diameter of 110 mm, which mates with standardized pilot recesses in gearbox flanges and mounting plates. The motor uses frame size 090 and a keyway shaft profile for coupling, and a shaft seal helps block lubricant migration and airborne contaminants from the bearing area. The shaft seal also helps limit dust and splash entry at the shaft opening.
