Product Description:
The Bosch Rexroth Indramat MAC112B-1-PD-4-C/130-B-1/WI522LX belongs to the MAC AC Servo Motors series and is supplied as a motor for analog drives used in machine-tool and general automation axes. This model is a brushless AC servo unit designed to deliver controlled torque and speed to a matched drive controller, enabling closed-loop positioning, contouring, or spindle functions on production equipment. An integrated blocking brake is provided as standard to secure loads when the axis is idle.
A forced-air thermal design is built around axial surface cooling, and the external blower runs on 230 V AC, so cabinet air does not have to be diverted for motor ventilation. Under rated excitation, the rotor reaches 1500 rpm, a speed that aligns with gear ratios typically found on cutting or forming machines. A mechanical interface with a 130 mm centering diameter simplifies concentric mounting to precision gearboxes or flanges. For holding static loads, the integrated blocking brake supplies 45 Nm of torque, allowing vertical axes to remain stationary when power is removed. The overall motor length is coded as B, and the frame size is 112, balancing inertia and dynamic response.
Electrical terminations follow the series convention, with the power connection made through a connector on side B, which provides clearance when the motor is installed in tight enclosures. The stator winding marked PD establishes electrical constants compatible with Indramat analog drive amplifiers. Rotor position is reported by an incremental encoder with standard mounting, and the auxiliary tachogenerator outputs 3 V/1000 rpm. This standard signal assists the drive in detecting speed discrepancies at low revolutions. Tacho feedback quality is standard, and the combined encoder-tacho arrangement uses the WI522LX interface format.
