Product Description:

The MAC071C-2-GS-4-C/095-A-0/WI520LV/S001 AC servo motor is produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is a motor for analog drives that generates controlled torque and speed in industrial positioning axes and tooling spindles. By combining a permanent-magnet rotor with integrated tachometer feedback, the unit supports rapid response and accurate velocity regulation in automated machinery. Its design uses external drive amplification rather than embedded power electronics, which keeps the motor itself compact. This arrangement lets the paired amplifier handle current control while the motor focuses on electromechanical output.

Mechanical fit is governed by a centering pilot of 95 mm and by a DIN 6885 keyed shaft that secures torque transfer to the load. Cooling is provided by axial surface cooling, and a dedicated blower running at AC 115 V moves air across the housing fins to maintain thermal limits during continuous duty. The motor uses winding code GS, which corresponds to the electrical characteristics required by the matching drive. Under rated conditions, the rotor reaches a nominal speed of 6000 rpm, allowing high operating speeds for grinders or pick-and-place stations. Because no blocking brake is fitted, static holding must be provided by the drive or by external mechanical restraint when power is removed.

The built-in tachometer outputs 1.5 V/1000 rpm, providing an analog speed signal that the drive electronics can use for closed-loop control. Position feedback is handled by an incremental encoder with standard mounting, which supports consistent speed monitoring and position tracking during operation. Power is supplied through a connector on side A, which keeps cabling on the driven end of the machine frame. The motor has size 071 and length code C, giving it a compact form that fits installations with limited axial space. The short housing can leave more room for nearby couplings, pulleys, or other drivetrain components.
