Product Description:

The 1AD160L-B302-4A111 is a three-phase induction motor built by Bosch Rexroth Indramat for the 2AD 3-Phase Induction Motors series. It serves as the prime mover in automated machine tools, material-handling stations, and packaging systems, supplying continuous rotary motion that can be speed regulated by an inverter drive. The motor couples electrical input to mechanical torque without brushes, making it suitable for continuous-duty industrial automation tasks.

The motor has a frame size of 160, providing mounting dimensions compatible with IEC 160 housings. Its stator uses a 4-pole configuration, so synchronous frequency limits align with standard 50/60 Hz mains. The motor can be wired in a wye connection for nominal operation at 220 VAC, delivering up to 4000 rpm, or in a delta connection at 127 VAC to reach higher spindle speeds. When driven through an inverter, the rotor can accelerate to a maximum of 6000 rpm in the delta circuit while staying within mechanical balance limits and bearing ratings. These electrical options allow one machine frame to support both high-torque, low-speed duties and higher-speed applications.

Controlled operation begins at 20 rpm, enabling low-speed threading or indexing without encoder loss of lock. Rotor slip is permitted up to 150 rpm under heavy load before torque degrades, giving the drive a predictable speed-torque curve for closed-loop control. The cast-aluminum housing has an ingress rating of IP54, which shields the windings from dust and splashing fluids, while the external axial blower mounted on top is rated IP24, so cooling air can pass through the ducts while avoiding direct water exposure. Forced ventilation keeps stator temperature within limits across the speed range, and an electrically engaged clamp brake holds the shaft when power is removed to prevent drift on vertical axes.
