Product Description:

The MAC071C-0-JS-4-C/095-B-1/AM154SG is a servo motor built by Bosch Rexroth Indramat and part of the MAC AC Servo Motors series. Delivered for analog drives, it converts controlled electrical input into rotary motion for positioning and speed tasks in industrial automation. It is suited to packaging, transfer, and handling equipment that relies on consistent servo response. The housing, winding, and feedback interfaces are sized for mid-frame machines that need closed-loop axis control while remaining compact. Integrated mounting features let the unit bolt directly into assemblies without additional adapters.

The motor uses size code 071, which balances torque capacity with installation space. Its stack length is the C variant, extending the active iron for higher continuous output without changing flange geometry. A centering pilot of 95 mm aligns the flange to gearboxes or bearing blocks and helps keep radial runout low. Thermal losses are dissipated by natural convection, so no external blower or liquid cooler is required. Electromagnetic behavior is matched to compatible drive inverters through winding code JS, which sets the phase resistance, inductance, and current rating for this rotor and stator combination.

Rated speed reaches 2000 rpm, making the motor suitable for medium-speed axes such as conveyors, tool turrets, or material handlers. A blocking brake supplies 3 Nm of holding torque to secure the load when power is removed. Power is introduced through a connector on side B, which can simplify cable routing when the driven shaft faces side A. Position information is provided by an absolute encoder, and the tacho channel outputs 3 V per 1000 rpm to support analog speed loops in legacy control platforms. This combination allows the drive to monitor shaft position while the brake holds the axis at standstill.
