Product Description:

The 2AD104B-B050B1-CS06-B2N1 is an AC induction motor produced by Bosch Rexroth Indramat for the 2AD 3-Phase Induction Motors series. As a drive element, it couples with Rexroth converters to provide constant torque for machine tools, printing lines, and packaging axes. The unit has motor size 104 and length code B, giving it a medium frame that balances torque density with the available thermal surface area. Its induction design supports controlled speed and torque when connected to a compatible converter.

The blower receives 230 V, allowing it to be powered directly from a standard industrial control circuit. Cooling is provided by an external axial blower that moves air along the motor housing and removes heat generated by stator losses. This forced airflow allows continuous operation at rated current without relying solely on natural convection. Position information is returned through digital servo feedback, enabling the drive to monitor rotor speed without an external encoder. The motor uses flange mounting, which mates with an IEC B5 flange and aligns the housing concentrically with the driven machine. Electrical power and blower wiring are routed through a single power plug, reducing the number of separate connections and protecting the conductors against vibration.

The motor is supplied without a holding brake, so dynamic stopping must be performed by the inverter or an external mechanical device. The three-phase terminals are oriented toward Side B, keeping high-current cabling clear of coolant manifolds that may be installed on the opposite side. Dynamically balanced rotor components support vibration grade R, which limits radial oscillation in precision spindle applications. The primary shaft end is keyed and balanced with the entire key, while the opposite end has no shaft extension. Because the shaft is supplied without a shaft seal, an external sealing arrangement may be required when the motor is exposed to contaminants or fluids. Standard bearings carry the permitted radial and axial loads, and winding code CS identifies the installed stator winding arrangement.
