Product Description:

The 2AD104D-B05OB1-FS27-B2N1 is a flange-mounted actuator from Bosch Rexroth Indramat in the 2AD 3-Phase Induction Motors series. It is intended for three-phase applications that require rotary power for production lines, conveyors, and forming machines. When used with a compatible drive, the motor supports closed-loop torque and speed control for continuously running industrial equipment. This arrangement allows the drive to regulate motion while the motor supplies the mechanical output at the shaft. The design is suited to installations that need dependable operation and low routine maintenance.

Cooling is provided by an axial blower that moves ambient air across the stator laminations. This forced-air circuit is powered from a dedicated 230 V source, so the ventilation supply remains separate from the main motor feed. An electrically released brake is mounted on the non-drive end and provides up to 24 Nm of holding torque when it is de-energized. When the brake is energized, the rotor can turn normally during commanded motion. Rotor position is monitored by a multiturn absolute encoder that sends digital feedback to the drive, allowing the shaft angle to be retained after a power interruption without a homing cycle.

The mechanical layout uses size 104 with length code D, giving the motor the proportions associated with this frame. A flange mounting interface and a balanced keyed shaft support direct coupling to driven equipment, and the shaft is made without a seal. Standard-class bearings and vibration grade R support general automation loads during normal operation. Power reaches the stator through a top plug oriented toward side B, and the blower uses the same connector style. The top-mounted connection arrangement can simplify cable routing where space is limited above or behind the motor. Side B has no secondary shaft, and winding code FS is intended for inverter-controlled induction motor operation.
