Product Description:

The 1AD160M-B3R1-4A111 is a three-phase AC induction motor built by Bosch Rexroth Indramat as part of the 2AD 3-Phase Induction Motors series. Designed for industrial automation, the unit delivers constant rotary power to machine tools, handling lines, and general-purpose drives where vector-controlled speed regulation is required. Its induction rotor works with a frequency inverter that energizes the stator through three balanced phases to produce torque without permanent magnets. This motor is well suited for applications that need steady output, repeatable speed response, and continuous industrial duty.

Electrical connection options use standard delta and wye topologies. In a delta connection, the windings are rated for 127 VAC and can be driven to a synchronous shaft speed of 6000 rpm. In wye, the same windings operate at 220 VAC, which limits top speed to 4000 rpm while reducing phase current. The stator is energized through three phases, and an integrated Axial Blower pushes air along the housing to remove heat so the motor can hold continuous current in enclosed cabinets. Two mounting positions separated by 180° simplify alignment of the power box with cable runs and help the motor fit different machine layouts.

Position feedback is provided by an incremental encoder, allowing the drive to close the speed loop with fine resolution during operation. A shaft-mounted electrically engaged clamp brake locks the rotor during standby to prevent load drift on vertical axes or other loads that must remain fixed at rest. Thermal monitoring comes from a thermistor embedded in the stator, giving the inverter early warning before insulation limits are reached and allowing protective action when temperatures rise. The motor uses a 4-pole design that balances torque production with moderate inertia, and the size 160 frame accommodates flange or foot mounting without additional adapters.
