2AD104D-B05OB1-ES16-A2N1
2AD 3-Phase Induction Motors
The Bosch Rexroth Indramat 2AD104D-B05OB1-ES16-A2N1 from the 2AD 3-Phase Induction Motors series is a high-performance AC Induction Motor designed for demanding industrial applications. This model features a Motor Size Code 104 frame and a Motor Length Code D, offering a balanced power-to-weight ratio for its class. It adopts a housing structure with a short-circuit rotor and is surface ventilated via solidly connected axial or radial fan units. Versatile installation is supported by flange mounting and a smooth Shaft Type without seal, ensuring compatibility across various machine designs.
Thermal management and connectivity are addressed through an integrated Axial Blower Voltage 230V system and a detachable Power Plug (Blower with plug) at the Top position, providing efficient airflow and serviceability. The unit employs Digital servo feedback with absolute accuracy of 0.02°, paired with Winding Code ES windings to guarantee precise speed and position control. Mechanical integrity is reinforced by Standard bearings and a Vibration Grade R rating, supporting continuous operation up to the specified service life. The absence of a Shaft End (Side B) simplifies coupling arrangements, while the robust enclosure resists environmental stressors.
Stopping dynamics are governed by an Electrically engaged (clamp) Brake delivering a holding torque of 30 Nm with a Nominal Terminal Voltage 24+-10% V and brake current 0.9 A. The brake system is characterized by a MOMENT OF INERTIA OF HOLDING BRAKE 0.0007 kgm2, MAX. BREAKING ENERGY 20,000 Ws, and fast response with both CLAMPING DELAY 50 ms and RELEASE DELAY 50 ms. This motor is rated for a MECHANICAL SERVICE LIFE 20,000 hours under normal operating conditions, making it an ideal choice for applications demanding reliable starting, precise positioning, and extended maintenance intervals.
