Product Description:

The MAC160D-0-ED-1-B/250-A-1/J1250/S01 is a three-phase servo motor from Bosch Rexroth Indramat’s MAC AC Servo Motors series. Intended for analog drive systems, it converts commanded current or velocity signals into controlled rotary motion for positioning tables, forming machinery, and other automated equipment that rely on tight speed regulation and repeatable torque delivery. Its configuration suits applications that need stable servo response with external analog control rather than integrated digital drive functions. A standard blocking brake is built in so the shaft can be held when power is removed.

Under continuous duty, the motor can supply 84 Nm of mechanical torque while drawing a steady 69 A. This combination shows the long-term load the motor can carry without exceeding its thermal limits. The ED winding variant gives a torque constant of 1.360 Nm/A, so the drive can relate output torque to phase current. Rated mechanical speed reaches 1500 min⁻¹, allowing direct coupling to gearboxes or slow-running loads. Dynamic response is influenced by the rotor inertia of 0.1150 kg·m², which moderates acceleration peaks and helps the control loop remain stable when large inertia loads are attached.

A centering diameter of 250 mm aligns the housing with machine frames and supports concentric mounting. Heat is removed through natural convection, eliminating the need for external blowers and simplifying airflow around the motor. Position and velocity are returned to the drive using incremental encoder feedback, so the controller receives real-time shaft angle information without absolute reference data. Power conductors reach the stator via a connector on side A, which keeps cable routing directed to one side of the assembly and can simplify harness layout in multi-axis machines.
