Product Description:

The MAC160D-0-ED-1-B/250-A-0/J1250/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat as a member of the MAC AC Servo Motors series. Designed for use in industrial automation cells, this unit converts electrical energy into controlled mechanical rotation so that analog drive controllers can position tooling, conveyors, or material-handling axes with consistent accuracy. It works with an external analog controller to translate electrical commands into predictable rotary motion during starting, stopping, and speed changes. That operating role makes it suitable for packaging equipment, transfer systems, and other machines that rely on repeatable axis movement.

The rotor seats against a centering register that measures 250 mm, establishing the alignment reference for heavy flange assemblies. Heat produced by copper losses is removed through natural convection, so no external blower or liquid circuit is required. Position and speed feedback are produced by incremental encoder feedback, allowing the drive to close velocity and position loops with fine control. The stator windings use three-phase excitation for balanced torque generation and reduced vibration in precision equipment. For thermal safeguarding, an internal thermostat can switch auxiliary circuitry at up to 220 V AC, 1 A max if winding temperature rises above a safe limit.

The motor has no blocking brake, so static load retention must be supplied by external means or by drive torque. Without an onboard brake, the surrounding machine must provide a separate method of holding any load that cannot drift at standstill. Power is introduced through a connector on side A, which can simplify cable routing when the motor is mounted with its fan end toward service aisles. The ED winding sets the electrical characteristics expected by matching analog amplifiers. This configuration identifies the unit as a motor for analog drives rather than a motor intended for a fully digital fieldbus interface.
