Product Description:

The MAC112A-0-ZD-4-C/130-A-0/DI520LX/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive systems, it converts electrical input from a matched controller into controlled rotary motion for precise positioning and stable speed control on industrial machine axes. Because the motor does not include a blocking brake, holding force at standstill must be provided by the drive or by external mechanical hardware. This makes the unit suitable for applications that prioritize controlled motion during operation rather than load holding after power is removed.

The motor has a nominal speed of 1500 rpm, which sets its standard operating speed for matched drive combinations. Its flange uses a 130 mm centering diameter to align the housing accurately with machine interfaces, gearboxes, or mounting fixtures. Cooling is provided by natural convection, so the motor does not require a separate blower or liquid-cooling connection during normal use. Power conductors terminate at a connector on side A, which can simplify cable routing where one-sided access is preferred. Torque is transmitted through a DIN 6885 keyway, allowing the shaft to couple with common pulleys, hubs, or similar driven components.

The ZD winding code matches the resistance and inductance values used by compatible analog drive amplifiers, and the motor size 112 frame provides continuous torque suitable for mid-range axes. Speed feedback is supplied by a tacho generator with a tacho voltage of 3 V/1000 rpm, which gives the drive a linear signal for regulation across the operating range. Position data is provided by an incremental encoder with shock-damped mounting that resists vibration and supports precise axis control. This feedback combination allows the drive to monitor both speed and position without adding separate external sensing devices.
