Product Description:
The MAC112B-1-LD-4-C/130-A-1/DI524LX is a servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive current into rotational motion for positioning tasks in automated machinery, material-handling axes, and packaging modules. Its design combines tachometer feedback with encoder-based position sensing so the associated drive controller can regulate speed and position in closed-loop mode during continuous operation. This arrangement supports repeatable motion in systems that need stable speed control and accurate axis response.
The integrated blocking brake provides 45 Nm of holding torque, allowing vertical or load-bearing axes to remain fixed when power is off. An external blower rated at AC 230 V forces air over the housing fins, and the motor uses axial surface cooling so heat is carried along the length of the housing rather than collecting near one end. With a centering shoulder of 130 mm, the flange aligns precisely to gearboxes or machine frames and helps maintain accurate mounting geometry. At a nominal speed of 2000 rpm, the winding layout supports the intended operating range for analog drive systems. The motor uses frame size 112, which sets the shaft height, mounting hole pattern, and magnetic stack length.
Speed information is furnished by a tachogenerator that outputs 3 V per 1000 rpm, and this low-level signal lets analog velocity loops respond directly without digital conversion. For position data, the motor carries an incremental encoder with shock-damped mounting, which helps protect the sensing elements from vibration transmitted through the machine frame. Coil characteristics grouped under winding code LD match the motor to standard MAC drives, balancing inductance and resistance so current rise times remain compatible with analog control amplifiers. The feedback devices are integrated into the motor housing, which helps keep the installation compact and reduces the need for additional external components.
