Product Description:

The MAC112D-0-ED-3-C/130-A-2 is a servo motor produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Designed for analog drives, it converts drive commands into precise shaft motion for positioning and velocity control in industrial automation cells. A heavy-duty blocking brake is integrated to hold loads whenever the drive is disabled. This arrangement is useful on transfer axes, feed systems, and handling equipment that must stop accurately and remain fixed between commanded moves.

To secure static loads, the integrated heavy-duty blocking brake delivers 60 Nm of holding torque, preventing shaft rotation during power-off states. Accurate mechanical alignment is supported by a centering diameter of 130 mm, which matches common mounting flanges on medium-frame gearboxes. Heat generated by the stator is removed through natural convection, eliminating the need for external blowers and keeping the housing sealed. The motor has length code D, which provides space for a longer active section, and frame size 112, which places it in a medium motor class for applications that need stable mounting and solid torque delivery.

During continuous operation, the rotor reaches a synchronous speed of 3000 rpm, which suits many positioning and speed-control tasks in general industrial machinery. The feedback package combines tacho feedback and a second shaft end, allowing simultaneous velocity monitoring and mechanical coupling to an auxiliary device when required. That tacho generator produces a calibration voltage of 3 V/1000 rpm, giving the drive a linear signal for analog speed loops. Winding designation ED indicates resistance and inductance values selected for high dynamic response. The tacho quality is standard, and power is introduced through a connector on side A, which can simplify cable routing when the motor is installed beside other cabinet-fed axes.
