MDD041B-N-100-N2G-050PB0
The MDD041B-N-100-N2G-050PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled current into high-speed rotary motion for positioning axes and light spindle duties in industrial automation. Size code 041 and length code B give the unit a compact profile that fits tight machine envelopes while still supporting rapid acceleration. Its synchronous design helps deliver repeatable motion on small axes used in electronic assembly lines, textile equipment, and compact machining centers.
Its mounting face includes a centering pilot of 50 mm, which helps keep the stator coaxial with adjoining mechanical frames during installation. Cabling exits toward the rear because the connectors are placed on Side B. A pluggable connector permits quick cable changes without rewiring the motor. The rotor supplies a continuous standstill torque of 1.35 Nm, allowing the axis to hold loads during dwell periods without excessive heating. When driven by a matched inverter, the motor reaches a nominal speed of 10000 rpm, which supports short cycle times in pick-and-place heads, textile spindles, and compact tool changers.
The motor is supplied without a blocking brake, so load holding during power-off states must rely on drive torque or an external locking mechanism. Position and velocity feedback are provided through resolver feedback, which supplies analog sine-cosine signals that remain reliable under thermal stress and electrical noise. This feedback arrangement allows the drive to monitor rotor position continuously during speed regulation and positioning tasks. Torque is transmitted through a single shaft with a keyway, and the front bearing region is fitted with a shaft seal to help limit contaminant ingress in enclosed industrial environments.
