Product Description:

The MAC071C-0-NS-3-C/095-B-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is supplied as a motor for analog drives and converts regulated three-phase power into controlled rotary motion for positioning tasks in machine tools, material-handling axes, and packaging stations. Its role is to translate amplifier current commands into smooth shaft rotation so the connected axis can accelerate, regulate speed, and settle accurately during repetitive cycles. By working with legacy analog amplifiers, the unit provides precise velocity and torque response without requiring a digital interface. This makes it suitable for established automation systems that continue to use analog motion control hardware.

Mechanically, the motor centers on a 95 mm centering diameter, allowing accurate shaft alignment against gearboxes or flanges. This centering feature helps the motor seat consistently during mounting, which supports coupling alignment and reduces unnecessary shaft loading. Thermal energy is removed through natural convection, so no auxiliary fan or liquid circuit is needed. The frame uses the 071 size code, and the C body length increases the active winding length for moderate torque output in a compact housing. Under nominal conditions, the rotor reaches 3000 rpm, a speed suited to standard spindle and conveyor applications. Power conductors terminate on a connector on side B, which helps with cable routing in confined machine spaces.

Signal feedback completes the control loop through tachofeedback with a second shaft end, enabling voltage-based speed detection and an auxiliary mechanical interface. The second shaft end can support auxiliary coupling where an external device must be driven from the rear of the motor. The built-in tachogenerator outputs 3 V/1000 rpm, giving the analog controller a proportional speed reference across the operating range. Magnetic characteristics follow the NS winding, which balances current demand and available torque for mid-range duty. Because the motor has no blocking brake, load holding or stopping at standstill must be handled by external hardware or by drive-produced torque. This arrangement is appropriate where the axis does not require an onboard holding device.
