Product Description:

The 2AD110C-B050A1-AS03-B21N is an AC induction motor built by Bosch Rexroth Indramat and assigned to the 2AD 3-Phase Induction Motors series. It is intended for three-phase mains supplies and serves as the prime mover in automated handling, material transport, and processing equipment where continuous rotation and high starting torque are required. The motor fits directly to machine frames through its front flange and, when paired with a compatible drive inverter, delivers closed-loop speed control for precise industrial positioning tasks. This arrangement supports stable operation in systems that need repeatable acceleration, steady running speed, and dependable torque delivery over long production cycles.

Heat is removed by an integrated axial blower, so the windings receive constant airflow independent of shaft speed, letting the unit hold full rating at low frequency. Rotor position and velocity are reported through high-resolution motor feedback, and the fine incremental signals improve servo loop accuracy. Mechanical attachment is standardized because the housing accepts flange mounting, aligning the centering pilot with the driven machine. The motor uses length code C, which corresponds to the active iron volume and continuous torque of this 110 mm frame. It also uses winding code AS, which corresponds to the coil impedance and voltage constant used with 300 V drives. The shaft exits the housing without a seal, so external protection is needed if liquids are present.

In installations where the inverter handles stopping, the motor arrives without a holding brake, removing residual drag during rapid cycles. Power conductors terminate on side A, simplifying wiring when that face is closest to the cabinet glands. The rear face is left without a shaft end, so only the primary output transmits torque and the overall depth is reduced. The working shaft is supplied balanced with the entire key, permitting direct coupling while keeping vibration inside ISO limits. This single-output arrangement can simplify coupling layout and leaves the non-drive end clear for compact machine installations.
