Product Description:

The MAC071C-0-G8-4-C/095-B-0/WI520LV is a servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog velocity and torque controllers, it accepts sinusoidal armature currents and converts them into precisely timed rotary motion for packaging, printing, and material-handling axes. The motor’s laminated stator core, rare-earth magnets, and closed-loop feedback options support stable speed regulation while maintaining compatibility with earlier drive topologies that remain in service across many automated machines. This makes the unit suitable for applications that need dependable rotary motion without requiring a more complex modern drive architecture.

Mechanical alignment relies on a 95 mm centering diameter, which seats the front flange precisely against machine surfaces. Heat is removed by natural convection, eliminating the need for external blowers and simplifying cabinet layouts. Its frame is identified as motor size 071, and the housing depth follows the motor length C code, giving the motor a balanced form factor for medium-duty axis movement. For safety stops, the unit is supplied without a blocking brake, so holding torque must be provided by the drive or by external clamps. This arrangement is useful on machines where passive cooling and straightforward mounting are preferred over added cooling hardware.

Electrical terminations are made through a connector on side B, keeping power cables clear of the driven shaft and helping maintain orderly cable routing around the motor body. Speed regulation can use a combined sensing package that provides tacho feedback with incremental or absolute encoder signals, so both velocity and position loops can reference the same motor shaft. The built-in tacho is rated as standard quality, which is suitable for general-purpose point-to-point motion where extremely high dynamic accuracy is not required. When incremental position data are needed, the motor supports a standard-mount incremental encoder, allowing analog drive amplifiers to close the position loop without additional external transducers. This feedback arrangement supports consistent motion control while keeping the overall installation compact.
