MDD041B-N-100-N2K-050PB0
The MDD041B-N-100-N2K-050PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It works with digital drive controllers to convert commanded current into precise rotary motion, allowing automation equipment to maintain accurate speed and position profiles during repeated cycling. Frame designation 041 and length code B describe a compact housing size that fits small transfer stations, electronics assembly heads, and feeder mechanisms where installation space is limited. This motor is intended for applications that need quick response, repeatable motion, and stable servo performance in a small mechanical envelope.
A centering diameter of 50 mm positions the motor accurately in the machine housing and helps keep alignment consistent during mounting. Power and feedback conductors exit on Side B, which can simplify cable routing when the driven side faces the machine. A single Connector carries the motor phases, resolver signals, and protective earth through one interface, which keeps external wiring straightforward. Continuous torque at standstill is 1.35 Nm, providing stable low-speed or holding performance when controlled by the drive. The motor is supplied without a blocking brake, so any power-off holding function must be provided by the machine or by maintained drive torque.
The motor has a nominal speed of 10000 rpm, which suits high-speed axes such as indexing wheels or directly coupled spindle-style mechanisms. Position information is returned through Resolver feedback, allowing the controller to close torque, speed, and position loops reliably even where electrical noise is present. The output shaft uses a keyway so couplings or drive elements can be secured with positive engagement during torque transmission. It also includes a shaft seal to help limit contamination or lubricant entry at the shaft opening. The motor uses a standard shaft end on the drive side only, leaving the rear area clear for nearby machine components without requiring an additional shaft extension.
