Product Description:

The MAC112D-0-HD-4-C/130-B-0/WI520LV/S005 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a motor for analog drives that converts drive commands into precise mechanical rotation for positioning, conveying, or tooling axes in automated equipment. Its layout supports accurate motion control in machines that require stable speed response and repeatable axis movement during continuous operation. When paired with a compatible amplifier, it can support coordinated motion on transfer units, feeders, and other automated machine modules.

The centering flange is machined to 130 mm, allowing repeatable alignment with gearboxes or machine plates. Heat is removed through natural convection, so no external fan or coolant hookup is required. Under rated excitation, the rotor reaches 1500 rpm, which suits common 4-pole drive arrangements. Power enters through a connector on side B, which helps keep the cable run clear of the shaft end on side A. The output shaft uses a DIN 6885 keyway, providing positive torque transfer to pulleys or couplings. The motor is built in length code D and does not include a blocking brake, so holding torque must be supplied by the drive or by an external clamping device. A standard tacho generator is installed for speed feedback, and its baseline quality is suitable for general servo duty.

The tacho generator outputs 3 V/1000 rpm, giving the controller a proportional signal for closed-loop velocity regulation. Position reporting can also be provided by an incremental encoder mounted in the same housing, which preserves the standard mounting depth. The winding code HD indicates the internal electrical layout used for this motor, while the motor size code 112 refers to the frame size used within the MAC platform. This combination gives the motor a practical balance of torque density, thermal behavior, and installation space for industrial motion systems. It also allows the unit to serve both speed-controlled axes and applications that need position monitoring without changing the basic motor housing.
