Product Description

MAC112B-1-LD-4-C/180-A-2/AM164SG/S029 is a servo motor. It is part of Bosch Rexroth?s MAC motor series. Salient features of MAC motors include support for tacho feedback, IP65 rated motor housing, multiple cooling methods including convection cooling and surface cooling, electronic commutation, low rotor inertia, and optional blocking brakes. Typical MAC motor applications include transfer facilities, handling equipment, machine tools and printing presses. The MAC112B-1-LD-4-C/180-A-2/AM164SG/S029 motor has a special centering diameter of 180 millimeters. Benefits of a larger centering diameter include more precise motor alignment, enhanced stability and rigidity, uniform load distribution, simple assembly and easier maintenance. The motor shaft includes a keyway and is suited to form-fitting shaft-hub connections. MAC112 AC motors are available with a special winding design that provides a highly smooth run. These motor are especially well-suited for applications such as grinding machines and precision lathes.

The MAC112B-1-LD-4-C/180-A-2/AM164SG/S029 motor is equipped with a heavy duty blocking brake. Technical specifications for the brake include 60 Nm holding torque, 24 Volts DC nominal voltage, 1.35 Amps nominal current, 150 milliseconds release delay, 30 milliseconds clamping delay and 3.5 kilograms weight. Performance specifications for the motor include 2000 RPM nominal speed rating, 29 NM continuous torque at standstill and 43.5 Nm continuous current at standstill. The motor supports surface cooling and comes with a factory-installed axial cooling fan. This fan requires 230 Volts AC external power supply. Optimal ambient temperature for the motor is 0 to 45 degrees Celsius. The optimal site elevation is 0 to 1000 meters. Unused MAC motors must be kept in storage where they are safe from dust, corrosive elements and strong shocks that could damage the motor. Only trained personnel should work with MAC motors
