Product Description:

The MAC112D-0-HD-4-C/130-A-0/WI1520LV belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a motor for analog drives that converts drive controller commands into precise rotary motion for industrial positioning tasks such as feed axes, transfer units, and similar machine movements. The unit works without a blocking brake, so any static holding force must be supplied by the external mechanics or by drive torque when the axis is stopped. Cooling is handled without an auxiliary fan, which suits installations where simple airflow management and reduced wiring are preferred.

The stator housing mates to a machine frame through a 130 mm centering diameter, and that interface matches the 112 frame size used across the series for this mechanical envelope. A compact length code D limits axial space while still supporting the magnetic stack required for the rated torque band, which helps when the motor must fit into short machine sections. Nominal output speed is 1500 rpm, which provides a practical operating speed for gearing and axis tuning in moderate-speed motion systems. Heat is removed by natural convection, so cooling takes place through surface radiation and surrounding airflow rather than with forced ventilation.

The power leads exit through a connector on side A, simplifying cable routing in cabinets where motors are installed in rows or where cable bends must be kept orderly near the mounting face. A permanent-magnet tacho generator delivers 3 V per 1000 rpm, giving the analog drive a proportional speed signal for closed-loop control and stable velocity regulation. Coil geometry follows winding code HD, so the electrical resistance and inductance align with drives that supply higher current at moderate voltage. Position feedback is handled by an incremental encoder, and the interface supports the incremental or absolute encoder feedback option.
