Product Description:

The MDD090C-N-020-N2L-130PR2 synchronous motor is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for direct coupling to digital drive controllers, the unit delivers commanded motion profiles to automated material-handling cells, gantries, and machining centers. It is intended for medium-frame servo axes that require precise velocity regulation, quick torque response, and stable tracking during repeated acceleration and deceleration. This operating profile suits coordinated machine movements in which multiple axes must start, stop, and hold position with consistent response.

The motor uses a centering seat of 130 mm, allowing rigid flange mounting and accurate alignment to the machine face. Power and feedback conductors exit on the right side, and the detachable connector arrangement simplifies cable routing where side access is preferred. Continuous torque at standstill reaches 10.4 Nm, so the axis can counter static process loads without overheating during normal holding duty. When power is removed, the integrated brake supplies 11.0 Nm of holding torque to limit drift on vertical or inclined axes. The rotor is balanced to a standard grade, the housing uses a standard enclosure, and the motor is identified by size 090 with length code C, which correspond to its flange pattern and overall body depth.

Position and velocity information is returned through Digital servo feedback (DSF), enabling closed-loop control up to a nominal speed of 2000 rpm. Torque is transmitted through a keyed shaft in a single-ended form, so there is no secondary shaft on side B. This layout leaves the rear side clear for the connection hardware and keeps the drive end dedicated to torque transfer. The output end is supplied with a shaft seal to help protect internal bearings from coolant splash and airborne particulates during routine machine operation.
