Product Description:
Bosch Rexroth Indramat manufactures the MAC071C-0-NS-4-C/095-A-1. This AC servo motor belongs to the MAC AC Servo Motors series and is intended for integration with analog drive amplifiers in automated material handling, packaging, or assembly stations. Its electromechanical design converts electrical input into controlled torque and speed so positioning systems can follow command signals with minimal delay. Because it is used in closed-loop motion service, it can support repeatable starts, stops, and speed changes during normal machine cycles.
An integral blocking brake is supplied as standard; it applies a holding torque of 3 Nm to secure the load during power-off or emergency stops. This brake also helps prevent axis drift when the motor is not actively driven. Mounting concentricity is achieved through the 95 mm centering shoulder that aligns the flange to the machine frame. The motor uses size code 071 and length code C, giving a compact frame with enough active material for sustained current handling. During continuous operation, the shaft reaches 3000 rpm, which supports quick indexing and stable speed control with compatible analog amplifiers.
Heat is removed by natural convection, eliminating fans and reducing the number of moving cooling parts as long as ambient airflow is available. Natural cooling also helps keep the installation simple because no separate forced-air hardware is required. For velocity feedback, the motor supports incremental or absolute encoder tacho feedback, allowing the drive to use pulse-based feedback or absolute position information. The built-in tacho generator supplies 3 V/1000 rpm for standard regulation tasks. Power and brake conductors exit through a connector on side A, which helps when cable space is limited behind the motor. The electromagnetic circuit follows winding code NS, matching the motor to analog amplifier characteristics across its speed range.
