Product Description:
The MAC112B-0-GD-1-B-130-A-1-S05J625 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts current from a drive controller into controlled rotary motion so that machine axes can be positioned accurately or follow speed commands in industrial automation equipment. The motor combines mechanical braking, passive thermal management, and position feedback for applications that require precise torque, repeatable positioning, and dependable load holding. Its configuration is suitable for automated machinery such as material-handling systems, packaging equipment, and machine tools controlled by compatible Indramat drive modules.
The motor includes a standard blocking brake, which uses an internal friction device that engages automatically whenever control power is removed. The brake provides up to 45 Nm of holding torque, helping suspended or driven loads remain stationary during downtime or emergency stops. Heat generated during normal operation is removed through natural convection; fins on the housing transfer thermal energy to the surrounding air without fans or liquid-cooling circuits. A centering pilot measuring 130 mm aligns the motor flange accurately with a gearbox or machine mounting plate. The motor has a frame size of 112, which indicates the stator diameter associated with this housing. Its length code is B, identifying the magnetic stack depth used for the motor’s torque and inertia characteristics.
The motor uses winding code GD, which identifies the resistance, inductance, and nominal voltage required for pairing with compatible analog drive modules. Rotor position information is generated through incremental encoder feedback, allowing the drive to regulate velocity and perform homing routines without an absolute reference device. The feedback signals give the controller the position changes needed to correct motion during operation and maintain stable closed-loop performance. Power conductors exit through a connector on side A, placing the connection on the service side of the machine frame. This connector orientation provides a clear cable-routing path when the motor is installed near surrounding equipment or within a confined machine assembly.
