Product Description:

The MDD071A-N-040-N2T-095GL0 is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is specified as a motor for digital drive controllers, meaning it receives regulated current from a drive and supplies precise rotary motion for position or speed control in automated stations. A 071 frame coupled with the A length code gives a short mechanical envelope, allowing installation in compact machinery while still delivering the dynamic response needed for repetitive industrial cycles.

A centering diameter of 95 mm sets the location reference for coupling the housing to adjacent fixtures, ensuring concentric alignment with driven shafts. At standstill, the motor can hold or slowly accelerate loads with 2.2 Nm of continuous torque under rated cooling and winding temperature. Once energized to its nominal point, the rotor can reach 4000 rpm, providing a wide speed range before field weakening is required. Rotor position is reported by an integrated multiturn absolute encoder, and this sensor counts multiple shaft revolutions so the control system knows the mechanical angle after power loss. Position data is transmitted to the drive through Digital servo feedback (DSF), which carries high-resolution information for tight loop closure and reduces cabling complexity compared with analog feedback formats.

Power and signal terminations face the operator because the connection hardware is on the left side, and a keyed circular connector simplifies cable attachment without rewiring. Shaft output is delivered through a plain shaft that mates to couplings or pulleys without keyways, minimizing imbalance when paired with the motor’s standard dynamic balancing. Mechanical holding is supplied by external devices since the unit is shipped without a blocking brake. To limit lubricant loss and protect the internal bearings, a shaft seal is fitted as standard, helping restrict dust and fluid ingress during continuous service.
