Product Description:

The MAC112C-0-ED-4-C/130-B-0/WI1520LV/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is classified as a motor for analog drives and converts drive commands into precise rotary motion for positioning tables, feeders, and other automation axes. The type code shows motor size 112 and length code C, placing the stator and rotor in a medium-frame housing that supports moderate continuous torque while keeping installation depth relatively compact. This layout suits machines that need consistent speed control and repeatable positioning without a large motor footprint.

At its rated operating point, the rotor turns at 3000 rpm, a nominal speed that matches common inverter frequencies used in analog servo loops. Heat developed in the windings is removed by natural convection, so no external blower or liquid circuit is needed and ambient airflow around the housing provides cooling. The flange has a 130 mm centering diameter that aligns the motor to gearboxes or machine frames with minimal radial runout. The motor uses MAC size code 112, and winding code ED indicates the phase resistance and inductance used for drive tuning. The built-in tacho generator provides speed feedback so the external controller can monitor motor speed during operation.

Electrical power is supplied through a connector on side B, allowing cable routing away from moving machine elements. The motor has no blocking brake, so holding torque must be provided by the drive or an external mechanical lock when the axis is idle. The tachogenerator outputs 3 V/1000 rpm for speed verification, a signal level recognized by legacy analog controllers. For position control, the motor carries an incremental encoder with standard mounting, which delivers quadrature pulses to external counting hardware. Separate speed and position signals allow the motor to work with control hardware that uses both tacho feedback and pulse counting.
